  \title Introducing Qt Creator

    Qt Creator is an integrated development environment (IDE) that provides you with
    tools to design and develop complex applications for multiple desktop and mobile
    platforms.

    \image qtcreator-overview.png "Qt Creator overview"

    \section1 Cross-platform Development

    One of the major advantages of Qt Creator is that it allows a team of developers
    to share a project across different development platforms with a common tool
    for development and debugging.

    The recommended way to build a project is to use a version control system.
    Store and edit only project source files and the .pro and .pri files (for qmake)
    or CMakeLists.txt and *.cmake files (for CMake). Do not store
    files generated by the build system or Qt Creator, such as makefiles,
    .pro.user, and object files. Other approaches are possible,
    but we recommend that you do not use network resources, for example.

    Qt Creator allows you to specify separate build settings
    for each development platform. By default, \l{glossary-shadow-build}{shadow builds} are used to
    keep the build specific files separate from the source.

    You can create separate versions of project files to keep platform-dependent
    code separate. You can use qmake
    \l{http://qt.nokia.com/doc/4.7/qmake-tutorial.html#adding-platform-specific-source-files}{scopes}
    to select the file to process depending on which platform qmake is run on.

    Items such as open files, breakpoints, and watches are stored in
    sessions. They are not considered to be part of the
    information shared across platforms.

    Qt Creator is integrated with cross-platform systems for build automation:
    qmake and CMake. In addition, you can import generic projects that do not use qmake
    or CMake, and specify that Qt Creator ignores your build system.

    In addition to Qt libraries, you can link your application to other
    libraries, such as system libraries or your own libraries. Further, your
    own libraries might link to other libraries. To be able to compile your
    project, you must add the libraries to your project. This also enables
    code completion and syntax highlighting for the libraries.
    The procedure of adding a library to a project depends on the the build
    system that you use.

    Qt Creator provides support for building and running Qt applications for
    desktop environment and mobile devices. When you install the \QSDK,
    the build and run settings for the Maemo and Symbian targets are set up
    automatically. However, you need to install and configure some additional software
    on the devices.

    \note The only supported build system for mobile applications in Qt
    Creator is qmake.

    Once your mobile application is ready, you can test it in the Qt Simulator.
    You can also connect Maemo and Symbian devices to your development PC and
    debug applications on the devices. After you have tested the application,
    you can deploy it on mobile devices.

    Developing applications for mobile devices is different from developing
    desktop applications. For more information, see
    \l{Optimizing Applications for Mobile Devices}.

    \section1 Projects

    But why do you need projects? To be able to build and run applications,
    Qt Creator needs the same information as a compiler would need. This information
    is specified in the project build and run settings.

    Creating a project allows you to:

        \list

            \o Group files together

            \o Add custom build steps

            \o Include forms and resource files

            \o Specify settings for running applications

        \endlist

    You can either create a project from scratch or import an existing
    project. Qt Creator generates all the necessary files, depending on the type of
    project you create. For example, if you choose to create a graphical user
    interface (GUI) application, Qt Creator generates an empty .ui file
    that you can modify with the integrated \QD.

    Qt Creator is integrated with cross-platform systems for build automation: qmake and
    CMake. In addition, you can import generic projects that do not use qmake or CMake,
    and specify that Qt Creator ignores your build system.

    \section1 Editors

    Qt Creator comes with a code editor and two integrated visual editors for designing
    and building
    graphical user interfaces (GUIs) from Qt widgets.

    \section2 Code Editor

    As an IDE, Qt Creator differs from a text editor in that it knows how to build and run
    applications. It understands the C++ and QML languages as code, not just as plain text. This allows
    it to:

    \list

        \o Enable you to write well formatted code

        \o Anticipate what you are going to write and complete the code

        \o Display inline error and warning messages

        \o Enable you to semantically navigate to classes, functions, and symbols

        \o Provide you with context-sensitive help on classes, functions, and symbols

        \o Rename symbols in an intelligent way, so that other symbols with the same name
         that belong to other scopes are not renamed

        \o Show you the locations in code where a function is declared or called

    \endlist

    \section2 UI Designer

    Qt Creator provides two integrated visual editors, \QD and \QMLD.

    \QD is a tool for designing and building graphical user interfaces (GUIs) from
    Qt widgets. You can compose and customize your widgets or dialogs and test
    them using different styles and resolutions.

    Widgets and forms created with \QD are integrated seamlessly with programmed code,
    using the Qt signals and slots mechanism, that lets you easily assign behavior to
    graphical elements. All properties set in \QD can be changed dynamically within the code.
    Furthermore, features like widget promotion and custom plugins allow you to use your
    own widgets with \QD.

    UIs that use widgets are clearly structured and enforce a platform look and feel,
    which makes them useful for traditional applications. However, they are static, and
    do not fully make use of the large high-resolution screens, touch input, and significant
    graphics power that are becoming common in portable consumer devices, such as mobile
    phones, media players, set-top boxes, and netbooks.

    \QMLD allows you to easily develop animations by using a declarative programming
    language called \l {http://doc.qt.nokia.com/4.7/qtquick.html}{QML}.
    In QML, a user interface is specified as a tree of objects with properties.

    You use a visual editor to create items, screens, and applications, as well as define changes
    in their state, transitions from one state to another, and user actions that change the
    states. \QMLD generates the necessary code for you.

    You can use Qt or JavaScript to implement the application logic.

      \section1 Languages

    You can use the code editor to write code in Qt C++ or in the
    \l {http://doc.qt.nokia.com/4.7/qtquick.html}{QML} declarative
    programming language.

    \section2 QML

    You can use QML to build highly dynamic, custom user interfaces from a rich set
    of QML elements. Qt Quick helps programmers and designers collaborate to build the
    fluid user interfaces that are becoming common in portable consumer devices, such as
    mobile phones, media players, set-top boxes and netbooks.

    QML is an extension to JavaScript, that provides a mechanism to declaratively build
    an object tree of QML elements. QML improves the integration between JavaScript and
    Qt's existing QObject based type system, adds support for automatic property bindings
    and provides network transparency at the language level.

    \section1 Targets

    Qt Creator provides support for building and running Qt applications for
    desktop environment (Windows, Linux, and Mac OS) and mobile devices (Symbian, Maemo,
    and MeeGo). Build settings allow you to quickly switch between build targets.

    When you build an application for a mobile device target with a device
    connected to the development PC, Qt Creator generates an installation package,
    installs in on the device, and executes it.

    You can publish the installation packages on the \l{https://publish.ovi.com/info/}{Ovi Store}.
    For Symbian devices, the packages must be signed.

    \section1 Tools

    Qt Creator is integrated with a set of helpful tools, such as version control
    systems and Qt Simulator.

    \section2 Version Control Systems

    Qt Creator uses the version control system's command line clients to access
    your repositories. The following version control systems are supported:

    \list

        \o Git

        \o Subversion

        \o Perforce

        \o CVS

        \o Mercurial

    \endlist

    The functions available to you in Qt Creator depend on the version control
    system. Basic functions are available for all the supported systems. They include
    comparing files with the latest versions stored in the repository and displaying the
    differences, viewing versioning history and change details, annotating files,
    and committing and reverting changes.

    \section2 Qt Simulator

    You can use the Qt Simulator to test Qt applications that are intended
    for mobile devices in an environment similar to that of the device. You
    can change the information that the device has about its configuration
    and environment.

    The Qt Simulator is installed as part of the \QSDK. After it is
    installed, you can select it as a build target in Qt Creator.

    \section1 Debuggers

    Qt Creator does not include a debugger. It provides a debugger plugin that acts
    as an interface between the Qt Creator core and external native debuggers:

    \list

        \o GNU Symbolic Debugger (gdb)

        \o Microsoft Console Debugger (CDB)

        \o internal JavaScript debugger

    \endlist

    You can use the Qt Creator \gui Debug mode to inspect the state of your
    application while debugging. You can interact with the debugger in several
    ways, including the following:

    \list
        \o Go through a program line-by-line or instruction-by-instruction.
        \o Interrupt running programs.
        \o Set breakpoints.
        \o Examine the contents of the call stack.
        \o Examine and modify registers and memory contents of
           the debugged program.
        \o Examine and modify registers and memory contents of
           local and global variables.
        \o Examine the list of loaded shared libraries.
        \o Create snapshots of the current state of the debugged program
           and re-examine them later.
    \endlist

    Qt Creator displays the raw information provided by the native debuggers
    in a clear and concise manner with the goal to simplify the debugging process
    as much as possible without losing the power of the native debuggers.

    In addition to the generic IDE functionality provided by stack view, views for
    locals and watchers, registers, and so on, Qt Creator includes
    features to make debugging Qt-based applications easy. The debugger
    plugin understands the internal layout of several Qt classes, for
    example, QString, the Qt containers, and most importantly QObject
    (and classes derived from it), as well as most containers of the C++
    Standard Library and some gcc and Symbian extensions. This
    deeper understanding is used to present objects of such classes in
    a useful way.

    If you install Qt Creator as part of a \QSDK, the GNU Symbolic Debugger
    is installed automatically and you should be ready to start debugging after
    you create a new project. However, you can change the setup to use debugging
    tools for Windows, for example.

    You can connect mobile devices to your development PC and debug processes
    running on the devices.

    \title Qt Creator User Interface

    \image qtcreator-breakdown.png

    When you start Qt Creator, it opens to the \gui Welcome mode, where you can:

    \list

        \o Open tutorials and example projects

        \o View tips and hints on using Qt Creator

        \o Create and open projects

        \o Send feedback to the development team

        \o Open recent sessions and projects

        \o Read news from the Qt labs

        \o Ask for support

    \endlist

    You can use the mode selector to change to another Qt Creator mode.

    Qt Creator has been localized into several languages. If the system language
    is one of the supported languages, it is automatically selected. To change
    the language, select \gui {Tools > Options > Environment} and select a language
    in the \gui Language field. The change takes effect after you restart Qt Creator.

    \section1 Qt Creator Modes

    The mode selector allows you to quickly switch between tasks such as
    editing project and source files, designing application UIs,
    configuring how projects are built and
    executed, and debugging your applications. To change modes, click the
    icons, or use the \l{keyboard-shortcuts}{corresponding keyboard shortcut}.

    You can use Qt Creator in the following modes:

    \list
        \o \gui{\l{Using the Editor}{Edit}} mode for editing project and source files.
        \o \gui{\l{Developing Application UI}{Design}} mode for designing and developing
           application user interfaces. This mode is available for UI files (.ui or
           .qml).
        \o \gui{\l{Debugging}{Debug}} mode for inspecting the state of your program while
           debugging.
        \o \gui{\l{Managing Projects}{Projects}} mode for configuring project building and
           execution. This mode is available when a project is open.
        \o \gui{\l{Getting Help}{Help}} mode for viewing Qt documentation.
    \endlist

    Certain actions in Qt Creator trigger a mode change. Clicking on
    \gui {Debug} > \gui {Start Debugging} > \gui {Start Debugging}
    automatically switches to \gui {Debug} mode.


    \section1 Browsing Project Contents

    The sidebar is available in the \gui Edit and \gui Debug modes.
    Use the sidebar to browse projects, files, and bookmarks, and to view
    the class hierarchy.
    \image qtcreator-sidebar.png

    You can select the content of the sidebar in the sidebar menu:
    \list
        \o \gui Projects shows a list of projects open in the current
           session.
        \o \gui{Open Documents} shows currently open files.
        \o \gui Bookmarks shows all bookmarks for the current session.
        \o \gui{File System} shows all files in the currently selected
            directory.
        \o \gui {Class View} shows the class hierarchy of the currently
            open projects.

    \title Developing Application UI

    You can use the integrated \QD to design and build graphical user interfaces (GUIs) from
    Qt widgets. You can compose and customize your widgets or dialogs and test
    them using different styles and resolutions.

    Widgets and forms created with \QD are integrated seamlessly with programmed code,
    using the Qt signals and slots mechanism, that lets you easily assign behavior to
    graphical elements. All properties set in \QD can be changed dynamically within the code.
    Furthermore, features like widget promotion and custom plugins allow you to use your
    own widgets with \QD.

    UIs that use widgets are clearly structured and enforce a platform look and feel,
    which makes them useful for traditional applications. However, they are static, and
    do not fully make use of the large high-resolution screens, touch input, and significant
    graphics power that are becoming common in portable consumer devices, such as mobile
    phones, media players, set-top boxes, and netbooks.

    You can easily develop animations by using a declarative programming
    language called \l {http://doc.qt.nokia.com/4.7/qtquick.html}{QML}.
    In QML, a user interface is specified as a tree of objects with properties.
    You can edit QML code in the code editor or in the integrated \QMLD. You
    can use Qt or JavaScript to implement the application logic.

    The integration includes project management and code completion.

    The following sections describe how to develop application UI:

       \list

    \title Using the Editor

    Qt Creator's code editor is designed to aid you in creating, editing and
    navigating code.  Qt Creator's code editor is fully equipped with syntax
    checking, code completion, context sensitive help and in-line error
    indicators while you are typing.

    \section1 Using the Editor Toolbar

    The editor toolbar is located at the top of the editor view. The editor
    toolbar is context sensitive and shows items relevant to the file currently
    open in the editor.

    \image qtcreator-editortoolbar-symbols.png

    Use the toolbar to navigate between open files and symbols in use.
    To browse forward or backward through your location history, click
           \inlineimage qtcreator-back.png
           and \inlineimage qtcreator-forward.png
           .

    To go to any open file, select it from the \gui{Open files} drop-down menu.
    Right-click the menu title and select \gui {Copy Full Path to Clipboard} to
    copy the path and name of the current file to the clipboard.

    To jump to any symbol used in the current file, select it from the
    \gui Symbols drop-down menu. By default, the symbols are displayed in the
    order in which they appear in the file. Right-click the menu title and select
    \gui {Sort Alphabetically} to arrange the symbols in alphabetic order.

    \section1 Splitting the Editor View

    Split the editor view when you want to work on and view multiple files on
    the same screen.

    \image qtcreator-spliteditorview.png

    You can split the editor view in the following ways:
    \list
        \o To split the editor view into a top and bottom view, select
           \gui Window > \gui Split or press \key{Ctrl+E, 2}.

           Split command creates views below the currently active editor view.
        \o To split the editor view into adjacent views, select
           \gui Window > \gui{Split Side by Side} or press
           \key{Ctrl+E, 3}.

           Side by side split command creates views to the right of the
           currently active editor view.
    \endlist

    To move between split views, select \gui Window >
    \gui{Go to Next Split} or press \key{Ctrl+E, O}.

    To remove a split view, place the cursor within the view you want to
    remove and select \gui Window > \gui{Remove Current Split} or press
    \key{Ctrl+E, 0}. To remove all but the currently selected split view,
    select \gui Window > \gui{Remove All Splits} or press \key{Ctrl+E, 1}.

    \section1 Semantic Highlighting

    Qt Creator understands the C++ and QML languages as code, not as plain text.
    It reads the source code, analyzes it, and highlights it based on the
    semantic checks that it does for the following code elements:

    \list

        \o Types (such as classes, structs, and type definitions)

        \o Local variables

        \o Class fields

        \o Virtual methods

    \endlist

    To specify the color scheme to use for semantic highlighting, select
    \gui {Tools > Options... > Text Editor > Fonts & Color}.

    Qt Creator supports syntax highlighting also for other types of files than
    C++ or QML. For more information, see \l{Generic Highlighting}.

    \section1 Highlighting and Folding Blocks

    Use block highlighting to visually separate parts of the code that belong
    together. For example, when you place the cursor within the braces,
    the code enclosed in braces is highlighted.

    \image qtcreator-blockhighlighting.png

    To enable block highlighting, select \gui Tools > \gui{Options...} >
    \gui{Text Editor} > \gui Display > \gui{Highlight blocks}.

    Use the folding markers to collapse and expand blocks of code within
    braces. Click the folding marker to collapse or expand a block. In the
    figure above, the folding markers are located between the line number and
    the text pane.

    To show the folding markers, select \gui Tools > \gui{Options...} >
    \gui{Text Editor} > \gui Display > \gui{Display folding markers}. This
    option is enabled by default.

    When the cursor is on a brace, the matching brace is animated
    by default. To turn off the animation and just highlight the block and
    the braces, select \gui {Tools > Options... > Text Editor > Display} and
    deselect \gui {Animate matching parentheses}.


    \section1 Checking Code Syntax

    As you write code Qt Creator checks code syntax. When Qt Creator spots a
    syntax error in your code it underlines it and shows error details when you
    move the mouse pointer over the error.
    \list
        \o Syntax errors are underlined in red.

           In the following figure, a semicolon is missing at the end of the
           line.

           \image qtcreator-syntaxerror.png
        \o Semantic errors and warnings are underlined in olive.

           In the following figure, the type is unknown.

           \image qtcreator-semanticerror.png
    \endlist


    \section1 Completing Code

    As you write code, Qt Creator suggests properties, IDs, and code
    snippets to complete the code. It provides a list of context-sensitive
    suggestions to the statement currently under your cursor.

    \image qtcreator-codecompletion.png

    To open the list of suggestions at any time, press \key{Ctrl+Space}.
    If only one option is available, Qt Creator inserts it automatically.

    When completion is invoked manually, Qt Creator completes the common prefix
    of the list of suggestions. This is especially useful for classes with
    several similarly named members. To disable this functionality, uncheck
    \gui{Autocomplete common prefix} in the code completion preferences.
    Select \gui Tools > \gui{Options...} > \gui{Text Editor} > \gui Completion.

    By default, code completion considers only the first letter case-sensitive.
    To apply full or no case-sensitivity, select the option in the
    \gui {Case-sensitivity} field.

    \section2 Summary of Available Types

    The following table lists available types for code completion and icon
    used for each.

    \table
        \header
            \o Icon

    \title Pasting and Fetching Code Snippets

    In Qt Creator, you can paste snippets of code to a server or fetch
    snippets of code from the server. To paste and fetch snippets of code,
    Qt Creator uses the following:
    \list
        \o \gui{CodePaster}
        \o \gui{Pastebin.Com}
        \o \gui{Pastebin.Ca}
    \endlist

    To configure the server, select \gui{Tools} > \gui{Options...} >
    \gui{Code Pasting}.

    To paste a snippet of code onto the server, select \gui{Tools} >
    \gui{Code Pasting} > \gui{Paste Snippet...} or press \key{Alt+C,Alt+P}.

    To fetch a snippet of code from the server, select \gui{Tools} >
    \gui{Code Pasting} > \gui{Fetch Snippet...} or press \key{Alt+C,Alt+F}.

    \note To use \gui{Pastebin.Com}, configure the domain
    prefix in \gui{Tools} > \gui{Options...} > \gui{Code Pasting} >
    \gui{Pastebin.com}.

    For example, you might ask colleagues to review a change that you plan to
    submit to a version control system. If you use the Git version control system,
    you can create a \e{diff} view by selecting \gui{Tools} > \gui{Git} >
    \gui{Diff Repository}. You can then upload its contents to the server by choosing
    \gui{Tools} > \gui{Code Pasting} > \gui{Paste Snippet...}. The reviewers can retrieve
    the code snippet by selecting \gui{Tools} > \gui{Code Pasting} > \gui{Fetch Snippet...}.
    If they have the project currently opened in Qt Creator, they can apply and test
    the change by choosing \gui{Tools} > \gui{Git} > \gui{Apply Patch}.

    \title Using an External Editor

    To open the file you are currently viewing in an external editor, select
    \gui Edit > \gui Advanced > \gui{Open in External Editor}.

    To use the external editor of your choice:
    \list 1
        \o Add the editor path to the \c{PATH} environment variable of your
           operating system.
        \o In Qt Creator select \gui Tools > \gui Options... >
           \gui Environment > \gui General.
        \o In \gui{External editor} enter the name of the application followed
           by \key Space and \tt{\bold %f}. For example, to open the file in
           Smultron, enter \tt{\bold{smultron %f}}.

           To further define how to open the file in the external editor, you
           can use the following variables separated by a space:
           \list
            \o Current line number \tt{\bold %l}
            \o Current column number \tt{\bold %c}
            \o Editor's x position on the screen \tt{\bold %x}

    \title Configuring the Editor

    Qt Creator allows you to configure the text editor to suit your specific
    needs. To configure the editor, select  \gui Tools > \gui{Options...} >
    \gui{Text Editor}.

    \image qtcreator-font-colors.png "Text editor options"

    You can perform the following configuration actions:
    \list
        \o Set the font preferences and apply color schemes for syntax highlighting in
           \gui{Font & Colors}.
        \o Specify definition files for syntax highlighting for other types of files than
             C++ or QML in \gui{Generic Highlighter}.
        \o Set tabs, indentation, the handling of whitespace, and mouse operations in
           \gui Behavior.
        \o Set various display properties, for example,
           \l{Highlighting and folding blocks}{highlighting and folding blocks},
           text wrapping or \l{Moving to symbol definition or declaration}
           {moving to symbol definition or declaration}
           in \gui Display.
        \o Configure \l{Completing Code}{code completion} in \gui Completion.
    \endlist

    \section2 Configuring Fonts

    You can select the font family and size. You can specify a zoom setting in
    percentage for viewing the text. You can also zoom in or out by pressing
    \key {Ctrl++} or \key {Ctrl +-}, or by pressing \key Ctrl and rolling
    the mouse button up or down. To disable the mouse wheel function, select
    \gui {Tools > Options... > Text Editor > Behavior} and deselect the
    \gui {Enable scroll wheel zooming} check box.

    Antialiasing is used by default to make text look smoother and more
    readable on the screen. Deselect the \gui Antialias check box to
    turn off antialiasing.

    \section2 Defining Color Schemes

    You can select one of the predefined color schemes for syntax highlighting
    or create customized color schemes. The color schemes apply to highlighting
    both C++ and QML files and generic files.

    To create a color scheme:

    \list 1

        \o Select \gui {Tools > Options... > Text Editor > Fonts & Color > Copy}.

        \o Enter a name for the color scheme and click \gui OK.

        \o In the \gui Foreground field, specify the color of the selected
        code element.

        \o In the \gui Background field, select the background
        color for the code element.

        The backgound of the \gui Text element determines the background of the
        code editor.

    \endlist

    When you copy code from Qt Creator, it is copied in both plain text and HTML
    format. The latter makes sure that syntax highlighting is preserved when
    pasting to a rich-text editor.

    \section2 Generic Highlighting

    Generic highlighting is based on highlight definition files that are provided by the
    \l{http://kate-editor.org/2005/03/24/writing-a-syntax-highlighting-file/}{Kate Editor}.
    You can download highlight definition files for use with Qt Creator.

    If you have a Unix installation that comes with the Kate Editor, you might already
    have the definition files installed. Typically, the files are in a read-only directory,
    and therefore, you cannot manage them. Qt Creator can try to locate them and use them
    as fallback files, when the primary location does not contain the definition for the
    current file type. You can also specify the directory that contains preinstalled
    highlight definition files as the primary location.

    When you open a file for editing and the editor cannot find the highlight definition
    for it, an alert appears. You can turn off the alerts. You can also specify patterns
    for ignoring files. The editor will not alert you if highlight definitions for the
    ignored files are not found.

    To download highlight definition files:

    \list 1

        \o Select \gui {Tools > Options... > Text Editor > Generic Highlighter}.

        \image qtcreator-generic-highlighter.png "Generic Highlighter options"

        \o In the \gui Location field, specify the path to the primary location for
        highlight definition files.

        \o Click \gui {Download Definitions} to open a list of highlight definition files available for
        download.

        \image qtcreator-manage-definitions.png "Download Definitions dialog"

        \o Select highlight definition files in the list and click \gui{Download Selected
        Definitions}.

        \o Select the \gui {Use fallback location} check box to specify the secondary location
        where the editor will look for highlight definition files.

        \o Click \gui Autodetect to allow Qt Creator to look for highlight definition
        files on your system, or click \gui Browse to locate them in the file system
        yourself.

        \o In the \gui {Ignored file patterns} field, specify file patterns. You will not
        receive alerts if the highlight definitions for the specified files are not found.

        \o Click \gui OK to save your changes.

    \endlist


    \section2 Indenting Code

    \image qtcreator-indentation.png "Text Editor Behavior options"

    When you type code, it is indented automatically according to the selected
    options. Select a block to indent it when you press \key Tab.
    Press \key {Shift+Tab} to decrease the indentation.

    When you press \gui Backspace the indentation is decreased by one level,
    instead of one space, by default.

    By default, the tab-length in code editor is 8 spaces, but you can change
    it. The code editor can also determine whether tabs or spaces are used
    on the previous or next line and copy the style.

    You can determine whether the block indent style includes braces,
    or you can use the GNU indent style. The GNU style places braces on a separate
    line, indented by 2 spaces, except when they open a function definition, where
    they are not indented.

    You can also specify whether continuation lines are aligned with the previous
    code or just indented to the logical depth. You can always use spaces for
    alignment or use spaces or tabs depending on the other options you selected.

    The following code snippet illustrates excluding braces from the indented block:

    \code

    void foobar(bool zoo)
    {
        if (zoo)
        {
            foo();
        }
    }

    \endcode

    The following code snippet illustrates including braces in the indented block:

    \code

    void foobar(bool zoo)
    {
        if (zoo)
            {
            foo();
            }
    }

    \endcode

    The following code snippet illustrates the GNU style:

    \code

    void foobar(bool zoo)
    {
      if (zoo)
        {
          foo();
        }
    }

    \endcode

    \title Refactoring

    Code refactoring is the process of changing the code without modifying the
    existing functionality of your application. By refactoring your code you
    can:
    \list
        \o Improve internal quality of your application
        \o Improve performance and extensibility
        \o Improve code readability and maintainability
        \o Simplify code structure
    \endlist

    \section1 Finding Symbols

    To find the use of a specific symbol in your project:

        \o In the editor place the cursor on the symbol and select \gui Tools
           > \gui C++ > \gui{Find Usages} or press
           \key Ctrl+Shift+U.

           Qt Creator looks for the symbol in the following locations:
           \list
            \o Files listed as a part of the project
            \o Files directly used by the project files (for example, generated
               files)
            \o Header files of used frameworks and libraries
           \endlist

        \note You can also select \gui{Edit > Find/Replace > Advanced Find >
        C++ Symbols} to search for classes, methods, enums, and declarations
        either from files listed as part of the project or from all files that
        are used by the code, such as include files.

        \image qtcreator-search-cpp-symbols.png

        \o The \gui{Search Results} pane opens and shows the location and
           number of instances of the symbol in the current project.

           \image qtcreator-refactoring-find.png
    \endlist

    You can browse the search results in the following ways:
    \list

        \o To clear the search results, click \inlineimage qtcreator-clear.png
           .
    \endlist

    \section1 Renaming Symbols

    The functions available for renaming symbols depend on whether you are
    writing C++ or QML code. For QML, you can only rename IDs.

    To rename a specific symbol in a Qt project:
    \list 1
        \o In the editor, place the cursor on the symbol you would like to
           change and select \gui Tools > \gui C++ >
           \gui{Rename Symbol Under Cursor} or press \key Ctrl+Shift+R.

           The \gui{Search Results} pane opens and shows the location and
           number of instances of the symbol in the current project.

           \image qtcreator-refactoring-replace.png
        \o To replace all selected instances, enter the name of the new symbol
           in the \gui{Replace with} text box and click \gui Replace.

           To omit an instance, uncheck the check-box next to the instance.

           \note This action replaces all selected instances of the symbol in
           all files listed in the \gui{Search Results} pane. You cannot
           undo this action.
    \endlist

    \note Renaming local symbols does not open the \gui{Search Results} pane.
    The instances of the symbol are highlighted in code and you can edit the
    symbol. All instances of the local symbol are changed as you type.

    To rename an ID in a Qt Quick project:

    \list 1

        \o Right-click an ID in the QML code and select
        \gui {Rename id}.

        \o In the \gui {Rename id} field, enter the new ID.

    \endlist

    \section1 Applying Refactoring Actions

    Qt Creator allows you to quickly and conveniently apply actions to refactor
    your code by selecting them in a context menu. The actions available depend on
    the position of the cursor in the code editor and on whether you are writing
    C++ or QML code.

    To apply refactoring actions to C++ code, right-click an operand, conditional
    statement, string, or name to open a context menu. In QML code, click an element
    ID or name.

    In the context menu, select \gui {Refactoring} and then select a refactoring action.

    You can also press \gui {Alt+Enter} to open a context menu that contains refactoring
    actions.

   \section2 Refactoring C++ Code

   You can apply the following types of refactoring actions to C++ code:

   \list

        \o Change binary operands

        \o Simplify if and when conditions (for example, move declarations out of
        if conditions)

        \o Modify strings (for example, set the encoding for a string to Latin-1, mark
         strings translatable, and convert strings to camel case)

        \o Create variable declarations

        \o Create method declarations and definitions

   \endlist

   \section2 Refactoring QML Code

   You can apply the following types of refactoring actions to QML code:

   \list

        \o Rename IDs

        \o Split initializers

        \o Move a QML element into a separate file to reuse it in other
        .qml files

   \endlist

    \title Managing Projects

    One of the major advantages of Qt Creator is that it allows a team of
    developers to share a project across different development platforms with a common
    tool for development and debugging.

    The following sections describe how to manage projects:

    \list
        \o \l{Creating a Project}
        \o \l{Setting Up a qmake Project}
        \o \l{Adding Libraries to qmake Projects}
        \o \l{Setting Up a CMake Project}
        \o \l{Setting Up a Generic Project}
        \o \l{Setting Up Development Environment for Maemo}
        \o \l{Setting Up Development Environment for Symbian}
        \o \l{Managing Sessions}
        \o \l{Adding New Custom Wizards}
    \endlist

    \title Creating a Project

    You use wizards to create and import several types of projects and files, such
    as Qt GUI or console applications and Qt Quick applications.
    You can use wizards also to add individual files to your projects.

    The wizards prompt you to enter the settings needed
    for that particular type of project and create the necessary files for you.
    To display other types of files in the \gui Projects pane, specify them in
    the project file.

    \image qtcreator-new-project.png

    To change the location of the project directory, and to make changes in
    the build and run settings, select \gui{Tools} > \gui{Options...} >
    \gui{Projects} > \gui{General}.

    \section1 Using Project Wizards

    To create a new project:
    \list 1
        \o Select \gui File > \gui{New File or Project} and select the type of your
           project.

           The contents of the following dialogs depend on the project type.
           Follow the instructions of the wizard.
           This example uses \gui {Qt Gui Application}.

        \o Name the project and set its path, and then click \gui Next.

           Do not use spaces and special characters in the project name and
           path.

           \image qtcreator-intro-and-location.png

        \o Select the Qt versions to use as build targets for your project, and click
           \gui{Next}.

           \image qtcreator-new-project-qt-versions.png "Qt Versions dialog"

           \note If you have only one Qt version installed, this dialog is skipped.

        \o Specify the name of the class you want to create and using the
           drop-down menu select its base class type.

           Note that the \gui{Header file}, \gui{Source file} and
           \gui{Form file} fields are automatically updated as you name your
           class.

           \image qtcreator-class-info.png
        \o Review the project settings.

           To create the project, click \gui Finish.

           \image qtcreator-new-project-summary.png
    \endlist

    \section1 Adding Files to Projects

    You can create the following types of files:

    \list

        \o Qt resource files, which allow you to store binary files in the
        application executable

        \o \QD forms and Qt QML files, which specify parts of application user
        interfaces

        \o C++ class, source, or header files

        \o Text files

    \endlist

    \section2 Creating C++ Classes

    The \gui {C++ Class Wizard} allows you to create a C++ header and source file for
    a new class that you can add to a C++ project. Specify the class name, base
    class, and header and source files for the class.

    The  wizard supports namespaces. To use a namespace, enter a qualified
    class name in the \gui {Class name} field. For example:
    MyNamespace::MySubNamespace::MyClass.

    \image qtcreator-cpp-class-wizard.png "Enter Class Name dialog"

    The names of the header and source file are based on the class name. To change the
    default suffix of a file, click \gui Configure.

    You can create your own project and class wizards. For more information,
    see \l{Adding New Custom Wizards}.

    \section2 Displaying Additional File Types in Projects Pane

    Qt Creator determines whether to display files from the project folder
    in the \gui Projects pane depending on the file type (.pro, .pri, .cpp,
    .h, .ui, .qrc, and so on). To display other types of files, edit the the
    project file. Add filenames as values of the \c {OTHER_FILES} variable.
    You can also use wildcards.

    For example, the following code specifies that text files are displayed
    in the \gui Projects pane:

    \code

    OTHER_FILES += *.txt

    \endcode

    This also makes the files available in the \gui Locator.

    \section1 Adding Subprojects to Projects

    When you create a new project, you can add it to another project as a subproject
    in the \gui{Project Management} dialog. However, you first have to edit the
    .pro file of the parent project to specify that qmake uses the \c subdirs template
    to build the project.

    The \c subdirs template creates a Makefile for building subprojects. They can be
    located either in subdirectories of the project directory or in any other directory.
    The location of the targets is specified using the SUBDIRS variable. If the project file
    has the same name as the directory, you can just specify the directory name. If the project
    name and directory name are different, you must specify the project file name (.pro).

    For more information on the SUBDIRS variable, see the
    \l{http://doc.qt.nokia.com/4.7/qmake-variable-reference.html#subdirs}{qmake Variable Reference}.

    For example, the following code specifies that plugin_coreplugin/plugin_coreplugin.pro
    and mylogin.pro belong to the project:

    \code
    TEMPLATE  = subdirs

    SUBDIRS = plugin_coreplugin \
    ../another/plugin/myplugin.pro
    \endcode

    To specify dependencies, use the \gui{Add Library} wizard. For more information,
    see \l{Adding Libraries to qmake Projects}.

    \title Adding New Custom Wizards

    If you have a team working on a large application or several applications,
    you might want to standardize the way the team members create projects
    and classes.

    You can copy the wizard templates in the template folders
    to create your own project and class wizards. They are displayed in the
    \gui New dialog that opens when you choose \gui {File > New File or Project}.

    In a project wizard, you can specify the files needed in a project.
    You can add wizard pages to allow developers to specify settings for the
    project.

    In a class wizard, you can allow developers to specify the class name, base
    class, and header and source files for the class.

    To see how this works, rename wizard_example.xml as wizard.xml in the helloworld
    and listmodels folders. After you restart Qt Creator, the \gui {Custom Classes}
    and \gui {Custom Projects} categories appear in the \gui New dialog.

    \image qtcreator-custom-project-wizards.png "The New dialog with custom projects and classes"

    \section1 Overview of Custom Wizards

    A custom wizard defines the user interface of a wizard page. The values the user enters
    in the wizard are assigned field names. Field name and value pairs are then passed to
    the file creation process. File creation can happen in the following ways:

    \list 1

        \o Template-based, where source files that contain placeholders for
        the field names are provided. During processing, the placeholders are replaced
        by the values from the wizard page. Optionally, modifier
        characters are applied. For more information, see \l{Processing Template Files}.

        \o Generator script, where a script is called to create the files.

        \note This option mainly exists to accommodate existing generator scripts or
        cases where complicated algorithmic logic is required when generating files. Writing
        cross-platform scripts is inherently difficult, and therefore, it is not recommended
        for new wizards. For more information, see \l{Using Generator Scripts}.

    \endlist

    Custom wizards are located in subdirectories of the following directories:

    \list

        \o \c{share/qtcreator/templates/wizards}

        \o the local user's configuration folder,
        \c{$HOME/.config/Nokia/qtcreator/templates/wizards}

        \o \c{%APPDATA%\Nokia\qtcreator\templates\wizards}

    \endlist

    They contain an XML configuration file called wizard.xml, the
    template source files, and optionally, the generator script.

    \section1 Creating Project Wizards

    To create a project wizard:

    \list 1

        \o Make a copy of the \c {share/qtcreator/templates/wizards/helloworld} or
        \c {share/qtcreator/templates/wizards/listmodel} folder.

        \o Modify the wizard_example.xml file.

        \o The following code determines the type of the wizard and its place
        in the \gui New dialog:

        \code

        <wizard version="1" kind="project"
        class="qt4project" firstpage="10"
        id="A.HelloWorld" category="B.CustomProjects">

        \endcode

        \list

            \o \c version is the version of the file contents. Do not modify this value.

            \o \c kind specifies the type of the wizard: \c project or \c class.

            \o \c class specifies the type of the project. Currently the only available
            type is \c qt4project, which specifies a Qt console project.

            \o \c firstpage specifies the place of the new page in the standard project
            wizard. The value 10 ensures that the custom page appears after the standard
            pages, as the last page of the wizard.

            \o \c id is the unique identifier for your wizard. The letter specifies the
            position of the wizard within the \c category. The HelloWorld wizard appears
            as the first wizard in the second category in the \gui New dialog.

            \o \c category is the category in which to place the wizard in the list.
            The letter specifies the position of the category in the list in the \gui New
            dialog.

        \endlist

        \o The following code specifies the icon and text that appear in the \gui New
         dialog:

        \code

        <icon>console.png</icon>
        <description>Creates a hello-world-project with custom message.</description>
        <description xml:lang="de">Erzeugt ein Hello-Welt-Projekt mit einer Nachricht.</description>
        <displayname>Hello World</displayname>;
        <displayname xml:lang="de">Hallo Welt</displayname>;
        <displaycategory>Custom Projects</displaycategory>
        <displaycategory xml:lang="de">Benutzerdefinierte Projekte</displaycategory>

        \endcode

        \list


            \o \c icon appears next to the \c displayName.

            \o \c description appears at the bottom of the \gui New dialog when you
            select the display name.

            \o \c displayName appears in the \gui New dialog, under the
            \c displayCategory.

            You can add translations as values for the text elements. Specify the target
            language as an attribute for the element. Use locale names (QLocale).
            For example, \c {xml:lang="de"}.

        \endlist

        \o Files to be added to the project:

        \list
            \o Template-based: The following code specifies the files to add to the project:
            \code
        <files>
            <file source="main.cpp" openeditor="true" />
            <file source="project.pro" target="%ProjectName%.pro" openproject="true" />
            <file source="icon.png" target="%ProjectName%.png" binary="true" />
        \endcode
            \list

                \o \c source specifies the file to copy to the project. The files must be
                located in the wizard folder.

                \o \c openeditor indicates that the file is to be opened in an editor after
                the wizard has finished.

                \o \c binary indicates that the file is a binary file (for example, an
                image file). It is to be copied to the target folder as is. Placeholders
                are not replaced with values.

                \o \c target specifies the new filename for the file. The \c {%ProjectName%}
                variable is replaced with the string that users specify in the \gui Name
                field on the first page of the wizard.

                \o \c openproject indicates that the file is a project file which is to be opened
                after the wizard has finished.

            \endlist

            See also \l{Processing Template Files}.

            \o Generator-script: The following code specifies that the script \c generate.pl is to be used
               to create the files:
            \code
            <generatorscript binary="generate.pl">
                <argument value="--class-name=%ClassName%"/>
                <argument value="--project-name=%ProjectName%"/>
                <argument value="--header-suffix=%CppHeaderSuffix%" omit-empty="true"/>
                <argument value="--source-suffix=%CppSourceSuffix%" omit-empty="true"/>
                <argument value="--description=%Description%" omit-empty="true" write-file="true"/>
            </generatorscript>
            \endcode
            In each argument, the field placeholders are replaced by the field
            values. There are additional boolean attributes which give fine-grained control:

            \list
            \o \c omit-empty specifies that complete argument is to be omitted when all
               placeholders expand to empty values. In the above example,
               the option \c --source-suffix will not be passed to the script if the value is empty.

             \o \c write-file indicates that instead of the expanded value,
                the value will be written to a temporary file and its file name will be
                passed to the script instead. This is useful for multi-line text fields.
            \endlist

             See also \l{Using Generator Scripts}.
        \endlist

        \o The following code creates a page that specifies settings for the project:

        \code

        <!-- Create a 2nd wizard page with parameters -->
        <fieldpagetitle>Hello World Parameters</fieldpagetitle>
        <fieldpagetitle xml:lang="de">Hallo Welt Parameter</fieldpagetitle>
        <fields>
            <field mandatory="true" name="MESSAGE">
                <fieldcontrol class="QLineEdit" validator='^[^"]+$'  defaulttext="Hello world!" />
                <fielddescription>Hello world message:</fielddescription>
                <fielddescription xml:lang="de">Hallo-Welt-Nachricht:</fielddescription>
            </field>
        </fields>

        \endcode

        \list

            \o \c fieldpagetitle specifies the title of the page.

            \o \c field specifies whether the field is mandatory (\c true or \c false).
            You can use the value of the \c name field as a variable in other files (for
            example, \c {%MESSAGE%}.

            \o \c fieldcontrol specifies the field. \c class specifies the field type.
            You can use interface objects from the QWidget class to create fields. This
            example uses QLineEdit to create an input field.

            \o \c validator specifies a regular expression to check the characters allowed in
            the field.

            \o \c defaulttext specifies text that appears in the field by default.

            \o \c fielddescription specifies the field name that appears on the wizard page.

         \endlist

    \endlist

    \section1 Creating Class Wizards

    The widget.xml file for a class wizard is very similar to that for a project
    wizard. The differences are discussed below.

    To create a class wizard:

    \list 1

        \o The following code specifies settings for the wizard:

        \code

        <wizard version="1" kind="class" id="A.ListModel" category="B.CustomClasses">

           <description>Creates a QAbstractListModel implementation.</description>
           <description xml:lang="de">Erzeugt eine Implementierung von QAbstractListModel.</description>

           <displayname>QAbstractListModel implementation</displayname>
           <displayname xml:lang="de">Implementierung von QAbstractListModel</displayname>

           <displaycategory>Custom Classes</displaycategory>
           <displaycategory xml:lang="de">Benutzerdefinierte Klassen</displaycategory>

        \endcode

        For more information about the elements and their values, see
        \l {Creating Project Wizards}.

        \o The following code specifies the files to add to the project:

        \code

        <files>
            <file source="listmodel.cpp" target="%ClassName:l%.%CppSourceSuffix%"  openeditor="true" />
            <file source="listmodel.h" target="%ClassName:l%.%CppHeaderSuffix%"  openeditor="true" />
        </files>

        \endcode

        Here, \c target contains the following variables that are used to construct
        the filename:

        \list

        \o \c {%ClassName:l%} is replaced with the value of the \c ClassName field.
        The modifier \c l converts the string to lower case, to observe Qt
        conventions.

        \o \c {%CppSourceSuffix%} and \c {%CppHeaderSuffix%} are pre-defined.
        For more information, see \l{Pre-defined Standard Variables}.

        \endlist

        \code

        <!-- Create parameter wizard page -->

        <fieldpagetitle>ListModel parameters</fieldpagetitle>
        <fieldpagetitle xml:lang="de">Parameter des ListModel</fieldpagetitle>
        <fields>
            <field name="ClassName">

                <fieldcontrol class="QLineEdit" validator="^[a-zA-Z0-9_]+$" defaulttext="MyListModel" />

                <fielddescription>Class name:</fielddescription>
                <fielddescription xml:lang="de">Klassenname:</fielddescription>
            </field>
            <field name="Datatype">

                <fieldcontrol class="QComboBox" combochoices="QString,int" defaultindex="0" />

                <fielddescription>Data type:</fielddescription>
                <fielddescription xml:lang="de">Datentyp:</fielddescription>
            </field>
        </fields>

        \endcode

        In addition to QLineEdit, QComboBox is used in the class wizard to create
        a field. \c combochoices specifies the options in the combobox and
        \c defaultindex specifies that QString is the default value.

    \endlist

    \section1 Processing Template Files

    When processing a template source file, placeholders specifying the field names
    in the format \c{%FIELDNAME%} are replaced by the values entered by the user.
    In addition, modifier characters are supported. For example, \c{%FIELDNAME:u%}
    specifies that the value is converted to upper case. This enables generating header
    guards for C++ header files.

    The following modifier characters are supported:

    \list
    \o \c{l} for lower case.
    \o \c{u} for upper case.
    \o \c{c} for upper case initial letter ("project" > "Project").
    \endlist

    You can use conditions to add sections of the file depending on field values.
    Use a syntax that is similar to C++ preprocessing, as demonstrated in
    the profile of the \c{helloworld} example:

    \code

    @if "%SCRIPT%" == "true"
    QT += script
    @endif

    \endcode

    The value of the Boolean (QCheckBox) field labeled \c{SCRIPT} determines
    whether the script module is added. The expressions must expand to valid
    Javascript expressions after field replacement.

    \section1 Pre-defined Standard Variables

    In addition to the field values entered by the user, you can use
    the following pre-defined standard values:

    \list

    \o \c {%ProjectName%} is replaced by the name of the project in the case
    of project wizards.

    \o \c {%Path%} is replaced by the path to the target directory.
    For classes, this is the directory, where the files
    are created. For project wizards, an additional subdirectory
    named after the project is created.

    \o \c {%TargetPath%} is replaced by the path to the directory where the actual files
    are created. For non-project wizards, it is identical to \c %Path%.
    For project wizards, it is \c %Path%/%ProjectName%.

    \o \c {%CppSourceSuffix%} is replaced by the default source suffix, which
    is defined in Qt Creator in \gui {Tools > Options... > C++ > File Naming}.
    For example, if users enter \bold MyClass, the filename becomes myclass.cpp
    when the project is created.

    \o \c {%CppHeaderSuffix%} is replaced by the default header suffix, which
    is also defined in \gui {File Naming}.

    \endlist

    \section1 Validating User Input

    You can specify validation rules for user input. The rules consist of a Boolean
    JavaScript expression and an error message. The placeholders in them are
    replaced with values before they are evaluated or displayed.

    Consider the following rule used in the \l{Creating Class Wizards} example:

    \code
    <validationrules>
        <validationrule condition='"%ClassName%" != "QAbstractListModel"'>
            <message>%ClassName% cannot be used as class name.</message>
            <message xml:lang="de">%ClassName% kann nicht als Klassenname verwendet werden.</message>
        </validationrule>
    </validationrules>
    \endcode

    It ensures that the class name entered by the user does not match the name of
    the base class. If the validation fails, a red label displaying the message appears
    at the bottom of the wizard page.

    \section1 Using Generator Scripts

    The values entered in the wizard page are passed to the script
    as command line arguments as defined by the wizard configuration file.

    In addition, the script must implement a \c{--dry-run} command line option.

    Qt Creator needs to know the file names before the files are created to check
    whether files with identical names already exist, for example. Therefore,
    script file generation is a two-step process:

    \list 1

    \o  Determine file names and attributes: The script is called with the command line
        \c{--dry-run} option and the field values. It then prints the relative path
        names of the files it intends to create, followed by comma-separated attributes
        matching those of the \c{<file>} element, for example:

        \code
        myclass.cpp,openeditor
        myclass.h,openeditor
        myproject.pro,openproject
        \endcode

    \o Create files: The script is called with the parameters only in the working directory.
       It then actually creates the files. If directories are needed, the script
       should create them, too.

   \endlist

   The \c{scriptgeneratedproject} sample wizard illustrates the usage.
   A typical script invocation for this example (obtained by running Qt Creator with
   \c{--customwizard-verbose}) looks as follows:

   \code
   generate.pl --class-name=TestClass --project-name=TestProject --header-suffix=h --source-suffix=cpp --description=/tmp/qtcreatorj26629.txt
   \endcode

   By default, the scripts are run in the directory corresponding to
   \c %TargetPath%. This can be overriden by specifying the
   attribute \c workingdirectory on the element \c generatorscript.
   For example, if the script creates the project directory by itself,
   %Path% can be specified. In that case, \c --dry-run should output
   the correct relative paths or absolute paths constructed using the value of
   \c %Path%.

    \title Setting Up a qmake Project

    The qmake tool helps simplify the build process for development projects
    across different platforms. qmake automates the generation of makefiles
    so that only a few lines of information are needed to create each makefile.
    qmake can be used for any software project, whether it is written in Qt or not.

    The qmake tool generates a makefile based on the information in a project
    file that is generated by Qt Creator. It can generate makefiles for MinGW,
    Microsoft Visual studio, and CSL ARM in Windows, and GNU Compiler Collection
    (GCC) in Linux and Mac OS X.

    For more information about qmake, see the
    \l{http://qt.nokia.com/doc/4.7/qmake-manual.html}{qmake Manual}.

    \section1 Selecting the Qt Version

    Qt Creator allows you to have multiple versions of Qt installed on
    your development PC and use different versions for each of your projects.

    If Qt Creator finds \bold qmake in the \c{PATH} environment variable, it uses
    that version. The \l{glossary-system-qt}{ qmake version of Qt} is referred
    to as \bold{Qt in PATH}. If you intend to use only one version of Qt and it
    is already in the \c{PATH} and correctly set up for command line use, you do
    not need to manually configure your Qt version.

    \section2 Compiling Projects with MinGW in Windows

    To add a Qt version for \bold MinGW:
    \list 1
        \o Select \gui Tools > \gui Options... > \gui Qt4 >
           \gui{Qt Versions}.
        \o Click \inlineimage qtcreator-windows-add.png
           and enter the name of the version in the \gui{Version name} field.
        \o Enter the qmake binary path in the \gui{qmake location} field.
        \o Enter the MinGW installation path in the \gui{MinGW directory} field.

           \image qtcreator-qt4-qtversions-win-mingw.png
    \endlist

    \section3 Troubleshooting MinGW Compilation Errors

    If error messages displayed in the \gui {Compile Output} pane contain
    paths where slashes are missing (for example, C:QtSDK),
    check your PATH variable. At the command line, enter the following commands:

    \code
        where sh.exe
        where make.exe
        where mingw32-make.exe
    \endcode

    If these commands show paths, they have been added to the global PATH variable
    during the installation of a toolkit based on Cygwin or MinGW, even though
    this is against Windows conventions.

    To keep working with the third-party toolkit, create a new shell link
    that adds the required paths (as Visual Studio and Qt do). The shell link
    must point to cmd.exe, as illustrated by the following example:

    \c {C:\Windows\System32\cmd.exe /K C:\path_to\myenv.bat}

    where the /K parameter carries out the command specified in the bat file.

    Create the myenv.bat file at \e path_to, which should be in a convenient location.
    In the file, specify the paths to the toolkits. For example,

    \c  {set PATH=C:\path1;C:\path2;%PATH%}

    where \e path1 and \e path2 are paths to the toolkits.

    Finally, remove the paths from the global PATH, reboot the computer, and
    run the \c where commands again to verify that the global PATH is now clean.

    You can use the shell link to run the tools in the third-party toolkits.

    \section2 Compiling Projects with Microsoft Visual C++

    To add a Qt version for a \bold{Microsoft Visual C++} compiler:
    \list 1
        \o Select \gui Tools > \gui Options... > \gui Qt4 >
           \gui{Qt Versions}.
        \o Qt Creator automatically sets the correct environment variables for
           compilation. Select the internal version number of the installed
           Microsoft Visual C++ tool chain in the \gui Toolchain list.

           \image qtcreator-qt4-qtversions-win-msvc.png

        \o If the \gui {Debugging helper} is not in use, click \gui Rebuild
        to take it to use. For more information, see \l{Using Debugging Helpers}.

    \endlist

    \section2 Compiling Qt for Symbian Projects

    If you are using \bold{Qt for Symbian} and your Symbian SDK is registered
    with devices.exe, Qt Creator automatically detects the Qt version. To add a
    Qt for Symbian version:
    \list 1
        \o Select \gui Tools > \gui Options... > \gui Qt4 >
           \gui{Qt Versions}.
        \o Select the \gui{S60 SDK} you want the Qt Creator to use.

           \image qtcreator-qt4-qtversions-win-symbian.png
        \o To build an application for your device using GCCE, enter the path
           to the CSL ARM toolchain directory in
           \gui{CSL\\GCCE Directory}.

           You do not need to specify this path if the compiler is included in
           the \c{PATH} environment variable.
        \o To build an application for the emulator (WINSCW toolchain), enter
           the path to your Carbide C++ installation directory in
           \gui{Carbide directory}.

           \note You need to have Carbide C++ version 2.0 or later installed.
    \endlist

    \section2 Compiling Projects With Linux

    To compile a project in Qt Creator, Linux uses GNU Compiler Collection
    (GCC). Intel Compiler Collection (ICC) is supported as a drop-in
    replacement for GCC.

    To add a Qt version:
    \list 1
        \o Select \gui Tools > \gui Options... > \gui Qt4 >
           \gui{Qt Versions}.
        \o Click \inlineimage qtcreator-linux-add.png
           and enter the name of the version in \gui{Version Name}.
        \o Enter the path to the qmake binary in \gui{Path to qmake}.
    \endlist

    \section2 Compiling Projects With Mac OS X

    To compile a project in Qt Creator, Mac OS X uses GNU Compiler Collection
    (GCC), which is part of Xcode.

    To add a Qt version:
    \list 1
        \o Select \gui{Qt Creator} > \gui Preferences... > \gui{Qt Versions}.
        \o Click \inlineimage qtcreator-macosx-add.png
           and enter the name of the version in \gui{Version Name}.
        \o Enter the path to the qmake binary in \gui{Path to Qmake}.

    \nextpage creator-project-cmake.html

    \title Adding Libraries to qmake Projects

    In addition to Qt libraries, you can add other libraries to your projects.
    The way the library is added depends on whether it is a system library or
    your own library or a 3rd party library located in the build tree of the
    current project or in another build tree.

    \image qtcreator-add-library-wizard.png "Add Library wizard"

    Because system libraries do not typically change and are often found by
    default, you do not need to specify the path to the library or to its includes
    when you add it.

    For your own libraries and 3rd party libraries, you need to specify
    the paths. Qt Creator tries to quess the include path for an external library,
    but you need to check it and modify it if necessary. Qt Creator automatically
    adds the include path for an internal library.

    For all libraries, select the target platforms for the application, library,
    or plugin.

    Specify whether the library is statically or dynamically linked. For a
    statically linked internal library, Qt Creator adds dependencies
    (PRE_TARGETDEPS) in the project file.

    Depending on the development platform, some options might be detected
    automatically. For example, on Mac OS, the library type (\gui Library or
    \gui Framework) is detected automatically and the option is hidden. However,
    if you develop on another platform than Mac OS and want to build your
    project for the Mac OS, you must specify the library type.

    The default convention on Windows is that the debug and release versions
    of a library have the same name,
    but are placed in different subdirectories, usually called \e debug and
    \e release. If the library path does not contain either of these folders,
    you cannot select the option to place the libraries in separate
    folders.

    Alternatively, the letter \e d can be added to the library name for the debug
    version. For example, if the release version is called example.lib, the
    debug version is called exampled.lib. You can specify that the letter
    is added for the debug version and removed for the release version.
    If the library name ends in \e d, deselect the \gui {Remove "d" suffix
    for release version} option.

    Qt Creator supports code completion and syntax highlighting for the added
    libraries once your project successfully builds and links to them.

    \section1 To Add Libraries

    \list 1

        \o In the \gui Projects pane, open the project file (.pro).

        \o Right-click in the code editor to open the context menu and select
        \gui {Add Library...}.

        \o Follow the instructions of the wizard.

    \endlist

    For more information about the project file settings, see
    \l{http://doc.qt.nokia.com/4.7/qmake-project-files.html#declaring-other-libraries}{Declaring other Libraries}.

    \section1 Example of Adding Internal Libraries

    The following example describes how to add a statically linked internal
    library to your project.

    \list 1

        \o Choose \gui {File > New File or Project... > Other Projects >
        C++ Library} to create the library.

        The \gui {Introduction and Product Location} dialog opens.

        \image qtcreator-add-library-wizard-ex-1.png "Introduction and Product Location dialog"

        \o In the \gui Type field, select \gui {Statically Linked Library}.

        \o In the \gui Name field, give a name for the library. For example,
        \bold mylib.

        \o Follow the instructions of the wizard until you get to the
        \gui {Project Management} dialog. In the \gui {Add to project}
        list, select a project. For example, \bold myapp.

        \o In the \gui Projects pane, open the project file (.pro).
        For example, \bold myapp.pro.

        \o Right-click in the code editor to open the context menu and select
        \gui {Add Library... > Internal Library > Next}.

        \o In the \gui Library field, select \bold mylib and click \gui Next.

        \o Click \gui Finish to add the following library declaration to the
        project file:

        \code
        win32:CONFIG(release, debug|release): LIBS += -L$$OUT_PWD/../../../projects/mylib/release/ -lmylib
        else:win32:CONFIG(debug, debug|release): LIBS += -L$$OUT_PWD/../../../projects/mylib/debug/ -lmylib
        else:symbian: LIBS += -lmylib
        else:unix: LIBS += -L$$OUT_PWD/../../../projects/mylib/ -lmylib

        INCLUDEPATH += $$PWD/../../../projects/mylib
        DEPENDPATH += $$PWD/../../../projects/mylib

        win32:CONFIG(release, debug|release): PRE_TARGETDEPS += $$OUT_PWD/../../../projects/mylib/release/mylib.lib
        else:win32:CONFIG(debug, debug|release): PRE_TARGETDEPS += $$OUT_PWD/../../../projects/mylib/debug/mylib.lib

    \title Building and Running Applications

    Qt Creator provides support for building and running Qt applications for
    desktop environment and mobile devices. When you install the \QSDK,
    the build and run settings for the Maemo and Symbian targets are
    set up automatically.

    You can add a target if the necessary tool chain is installed on the
    development PC and the Qt version is configured. Click
    \inlineimage qtcreator-qt4-addbutton.png "Add Target button"
    and select from a list of available
    targets. To remove a target, select it and click
    \inlineimage qtcreator-target-remove.png "Remove Target button"
    .

    You can select the targets and click the \gui Run button to build and
    run the applications on the targets. You can click the \gui {Build All}
    button to build all open projects, one after another.

     \section1 Setting Up a Project

    To view and modify the settings for currently open projects, switch to the
    \gui Projects mode by pressing \key Ctrl+5.

    \image qtcreator-projectpane.png

    The project pane consists of the following tabs:
    \list
       \o \l{Building for and Running on Multiple Targets}{Targets}
       \note If you have installed only one tool chain, the \gui Targets
       tab is replaced by a \gui {Build and Run} tab.
       \o \l{Specifying Editor Settings}{Editor Settings}
       \o \l{Specifying Dependencies}{Dependencies}
    \endlist

    Use the \gui Build and \gui Run buttons to switch between
    the build and run settings for the active project.

    If you have multiple projects open in Qt Creator, use
    \gui{Select a Project} option at the top to navigate between different
    project edits.

    \title Building for and Running on Multiple Targets

    You can build your application for multiple targets and run and debug it
    on the desktop and mobile devices. When you run the application on the
    \gui{Maemo} or \gui {Symbian Devices} target, Qt Creator copies the necessary
    files to the device that is connected to the deveopment PC. In addition, Qt
    Creator generates an installation package in the build directory. You can
    specify settings for deploying the files and creating the installation package.

    \section1 Building for and Running on Desktop

    \list 1

        \o Select \gui Desktop as the target.

        \o Click the \gui Run button.

    \endlist

    \section1 Building for and Running on Qt Simulator

    You can use the Qt Simulator to test Qt applications that are intended
    for mobile devices in an environment similar to that of the device. You
    can change the information that the device has about its configuration
    and environment.

    \list 1

        \o Select \gui {Qt Simulator} as the target.

        \o Click the \gui Run button.

    \endlist

    For more information about using the Qt Simulator, see the
    \l{http://doc.qt.nokia.com/qt-simulator-beta/index.html}{Qt Simulator Manual}.

    \section1 Building for and Running on Maemo

    \list 1

        \o Build and run the application for \l{Building for and Running on Qt Simulator}{Qt Simulator}.

        \o Build and run the application for \l{Using the Maemo Emulator}{Maemo Emulator}.

        \o Alternatively, you can build and run the application for a device:

        \list 1

        \o Set up the MADDE development environment and specify a connection
        to the device. For more information, see
        \l{Setting Up Development Environment for Maemo}.

        \o Connect the device to the development PC.

        \o Click the \gui Run button.

        \endlist

    \endlist

        Qt Creator uses the compiler specified in the MADDE toolchain to
        build the application.

        Qt Creator generates an installation package, installs it on the device,
        and executes the selected application.
        The application views are displayed on the Nokia N900.
        Command-line
        output is visible in the Qt Creator \gui {Application Output} view.

        Choose \gui {Projects > Maemo Run} to view the settings for deploying the
        application on the connected device and creating the installation package.
        For more information, see \l{Specifying Run Settings for Maemo Devices}.

        Debugging also works transparently.

    \section1 Building for and Running on Symbian

    \list 1

        \o Build and run the application for \l{Building for and Running on Qt Simulator}{Qt Simulator}.

        \o If no problems are found, build and run the application for a device.

        \o To test functionality that uses Symbian APIs, you can build and
        run the application for Symbian Emulator.

    \endlist

    The build configuration for the \gui{Symbian Device} target
    uses the GCCE tool chain by default. If you want to build
    for the device using RVCT, select it in the \gui {Tool chain} field
    in the \gui{General} section.

    \section2 Building and Running for a Device

    \list 1

        \o Install the required software on the device. For more information, see
        \l{Setting Up Development Environment for Symbian}.

        \o Connect the device to the development PC through a USB cable.
        The target selector displays a green check mark when a
        device is connected.

        \image qtcreator-qt4-symbian-device-connected.png

        The tool tip of the target selector shows more details about the actual
        device that will be used when you run your application.

        \o Start the \gui{App TRK} application on your device.

        \o Click the \gui Run button.

    \endlist

    You can connect several devices to your development PC simultaneously.
    In the details of the run configuration for the \gui{Symbian Device} target,
    select the device to run your application on.

    When you build the application for the \gui{Symbian Device} target, Qt
    Creator automatically generates a Symbian installation system (SIS) file
    in the project folder. You can deliver the installation file to users for
    installation on Symbian devices.

    When your application is ready for delivery to users, specify run settings
    for creating the final SIS installation packages. For more information,
    see \l{Creating SIS Installation Packages}.

    \section2 Building and Running for Symbian Emulator

    Select
    the \gui{Symbian Emulator} target as the active one, and build and run your
    project.

    \section2 Troubleshooting

    If you cannot build the application, check if:
     \list
        \o You selected the Symbian Device target for building the application.
        \o The settings for the Qt version you use to build your project are
           correct. The path to the Symbian SDK must point to the Symbian SDK
           installation directory.  Select \gui Tools > \gui Options...
           > \gui Debugger > \gui{Symbian TRK} and check if it points to the
           debugger toolchain.
     \endlist
    If you cannot run the application on a device, check if:
     \list
        \o The device is connected through the USB cable in \e{PC Suite} mode.
        \o \gui{App TRK} is running on the device, using the USB connection,
           with the status \e connected.
        \o The device is detected and selected in the run configuration
           details.
     \endlist

    If you cannot run the application in the emulator, check if:
     \list
        \o You selected the \gui{Symbian Emulator} target for your application.

        \o If you cannot select \gui {Symbian Emulator} as target, check that
        Carbide.c++ is installed correctly and that the path to the Carbide.c++
        installation directory is specified in the \gui{Carbide directory} field
        in the build settings.

        \o If the emulator process cannot be started, try closing Qt Creator and
           starting the application directly from your file manager. Having
           done this, Qt Creator should be able to run your projects in the
           emulator.

     \endlist

     \note Qt Creator does not create release configurations for the
     \gui {Symbian Emulator} target, because Symbian Emulator supports only debug
     builds.

    If this does not help to solve your problem, search the qt-creator@trolltech.com
    mailing list archives or provide feedback to us via the methods described on the
    \l{http://qt.gitorious.org/qt-creator/pages/Home}{Qt Creator Development Wiki}.


    \section1 Building with Remote Compiler

    The \gui {Remote Compiler} target is an interface to a compilation service at
    Forum Nokia. It provides a simple, standardized environment for building Qt
    applications and creating installation packages for Symbian and Maemo devices
    when you do not have the necessary tool chains and SDKs installed or they are
    not supported on the development PC. You can choose from a set of supported
    devices, such as S60 3rd Edition or S60 5th Edition devices.

    \note Remote Compiler is an experimental component that you must install
    separately from the package that is included in the \QSDK.

    \list 1

        \o In the \QSDK installation directory, double-click
        SDKMaintenanceTool.exe to install \gui {Experimental APIs}.

        \o In Qt Creator, choose \gui {Tools > Options > Projects > Remote Compiler}

    \title Specifying Build Settings

    Different build configurations allow you to quickly switch between
    different build settings. By default, Qt Creator creates \bold debug
    and \bold release build configurations.

    You specify build settings in the \gui Projects mode.

    \image qtcreator-projectpane.png

    To add a new build configuration, click \gui Add and select the type of
    configuration you would like to add. You can add as many build
    configurations as you need.

    To delete the build configuration currently selected, click \gui Remove.

    \section1 Editing Build Configurations

    To edit a build configuration:
    \list 1
        \o Select the build configuration you want to edit in
           \gui{Edit Build Configuration}.
        \o In section \gui General, you can specify:
        \list
            \o The \l{glossary-project-qt}{Qt version} you want to use to
               build your project. For more information, see
               \l{Selecting the Qt version}.
            \o The tool chain required to build the project.
            \o By default, projects are built in a separate directory
               from the source directory, as \l{glossary-shadow-build}{shadow builds}.
               This keeps the files generated for each target platform separate.

               \note Shadow building is not supported by the Symbian build system.
               Also, shadow building on Windows is not supported for Maemo.
               If you only build for one target platform, you can deselect
               the \gui{Shadow build} checkbox.
        \endlist
    \endlist

    \section1 Build Steps

    The build system of Qt Creator is built on qmake and make. In
    \gui{Build Steps} you can change the settings for qmake and make. Qt
    Creator runs the make command using the Qt version defined for the current
    build configuration.

    \image qtcreator-build-steps.png "Build steps"

    \section2 Adding Custom Build Steps

    To add custom steps to the build settings, select \gui {Add Build Step >
    Custom Process Step}.

    By default, custom steps are disabled. To activate a custom step, select
    the \gui{Enable custom process step} check-box.

    \image qtcreator-build-steps-custom.png "Custom Process Step"

    You can use any environment variables as values in the fields. For a list
    of variable names, click \gui {Build Environment > Details}. Variables are
    referenced using the platform's native syntax: $VARNAME or ${VARNAME} on
    Unix and %VARNAME% on Windows.

    \section1 Clean Steps

    You can use the cleaning process to remove intermediate files. This process
    might help you to fix obscure issues during the process of building a
    project.

    \image qtcreator-clean-steps.png "Clean steps"

    You can define the cleaning steps for your builds in the \gui{Clean Steps}:
    \list
        \o To add a clean step using make or a custom process, click
           \gui{Add Clean Step} and select the type of step you want to add.

           By default, custom steps are disabled. To activate a custom step,
           select the \gui{Enable custom process step} check-box.
        \o To remove a clean step, click \gui{Remove Item}.
        \o To change the order of steps, click
           \inlineimage qtcreator-movestep.png
           .
    \endlist

    \section1 Build Environment

    You can specify the environment you want to use for building in the
    \bold{Build Environment} section. By default, the environment in which Qt
    Creator was started is used and modified to include the Qt version.
    Depending on the selected Qt version, Qt Creator automatically sets the
    necessary environment variables. You can edit existing environment
    variables or add, reset and unset new variables based on your project
    requirements.

    \page creator-run-settings.html
    \nextpage creator-editor-settings.html

    \title Specifying Run Settings

    Qt Creator automatically creates run configurations for your project.
    To view and modify the settings, select \gui {Projects > Run}.

    The settings to specify depend on the type of the project: qmake project
    or Qt Quick project.

    Click \gui Add to add run settings for a project and \gui Remove to remove
    the current settings.

    \section1 Specifying Run Settings for qmake Projects

    The run configurations for qmake projects derive their executable from the parsed .pro
    files.

    \section2 Specifying Run Settings for Desktop Targets

    You can specify command line arguments to be passed to the executable
    and the working directory to use. The working directory defaults to
    the directory of the build result.

    For console applications, check the \gui{Run in Terminal} check box.
    If you need to run with special environment variables set up, you
    also do it in the run configuration settings.

    \image qtcreator-pprunsettings.png

    You can also create custom executable run configurations where you
    can set the executable to be run. For more information, see
    \l{Specifying a Custom Executable to Run}.

    \section2 Specifying Run Settings for Symbian Devices

    Qt Creator automatically detects Symbian devices that are connected to
    the development PC with an USB cable.
    If only one device is detected, the application is deployed
    and run on it. If multiple devices are connected to the PC,
    make sure that the correct device is selected in the
    \gui {Symbian Device} run settings for your project.

    You can also pass command line arguments to your application on the device.
    Press the \gui{Device info button} to get more information about the selected
    device, such as the CPU type and the running TRK version.

    \image qtcreator-symbian-run-settings.png "Run settings for Symbian devices"

    \section3 Creating SIS Installation Packages

    When you build the application for the \gui{Symbian Device} target, Qt
    Creator automatically generates a Symbian installation system (SIS) file
    in the project folder. You can deliver the installation file to users for
    installation on Symbian devices.

    The name of the installation file is displayed in the \gui {Installation file}
    field. In the \gui {Installation drive} field, select the drive on the device
    to install the application to. To suppress notifications on the device during the
    installation, select the \gui {Silent installation} check box. If the silent
    installation fails, Qt Creator attempts installation again, this time displaying
    notifications and error messages.

    Only installation files signed with a certificate and private key are
    allowed to be installed onto Symbian devices. By default, Qt Creator
    self-signs the installation file. This self-signing allows you to install
    the application on a mobile  device but places limits on what you can do
    with the installation file, including:
    \list
       \o  Self-signed applications cannot access the more sensitive
           \l{Capabilities and Signing}{capabilities} of the mobile device.
       \o  Security warnings will be displayed when you install the self-signed
           application on a mobile device.
       \o  Self-signed applications cannot be distributed commercially on Ovi
           Store.
    \endlist

    To get around these limitations, you need to go through the Symbian Signed
    process. The Symbian Signed organisation manages a public key
    infrastructure to provide public authentication of the information in the
    application signing certificates. Their security partner can validate your
    certificate and give you a Publisher ID. Then, when you sign an
    application, other people can be confident that the information in your
    certificate is correct and that the application does actually come from you.

    There are also options that do not require you to get a Publisher ID. For
    more detail about how the Symbian Signed process works, see
    \l{http://developer.symbian.org/wiki/index.php/Complete_Guide_To_Symbian_Signed}
    {Complete Guide to Symbian Signed}.

    When you have your own certificate and private key, you can specify them in
    the \gui{Create SIS Package} step in the run settings.

    \image qtcreator-qt4-symbian-signing.png


    If your private key is protected by a passphrase, Qt Creator asks you for the
    passphrase when the package is signed and offers to store it. However, storing
    passphrases in Qt Creator presents a security risk. To make Qt Creator forget
    all saved passphrases, click \gui {Reset Passphrases}.

    \section3 Capabilities and Signing

    Capabilities allow the Symbian platform to control access by applications to
    the functionality provided by the platform APIs. Access to capabilities is
    determined by the device configuration and how the application has been signed.

    Symbian Signed offers the following signing options depending on the
    capabilities that the application accesses:

    \list

        \o \bold{Express signed} for applications that access only user and system
        capabilities.

        \o \bold{Certified signed} for applications that access also restricted or
        device manufacturer capabilities.

        \note You need to request the rights to access device manufacturer
        capabilities from the manufacturer.

    \endlist

    For more information about how to choose the appropriate signing option, see
    \l{http://developer.symbian.org/wiki/index.php/Symbian_Signed_For_Distributing_Your_Application}{Symbian Signed For Distributing Your Application}.

    If you select a signing option that does not allow the application to access
    the defined capabilities, installing the application on mobile devices
    fails. To avoid problems, only define capabilities and link libraries to a project
    if you really need them.

    For more information about capabilities and how you can check which ones you
    need, see
    \l{http://developer.symbian.org/wiki/index.php/Capabilities_(Symbian_Signed)}{Capabilities (Symbian Signed)}
    and
    \l{http://doc.qt.nokia.com/4.7/platform-notes-symbian.html#required-capabilities}{Required Capabilities for Qt Applications}.

    For more information on how to define capabilities for a project, see
    \l{http://doc.qt.nokia.com/4.7/qmake-platform-notes.html#capabilities}{Capabilities}.

    \section3 Creating Smart Installer for Symbian Packages

    To deploy Qt applications on Symbian devices, you must install the software that Qt applications
    require, typically Qt, QtWebkit, and Open C. Nokia Smart Installer for Symbian makes it easier
    for users to install Qt applications to Symbian phones by checking whether the device contains
    the necessary software and by installing the missing pieces.

    For this to work, the Nokia Smart Installer must be packaged with the Qt application. The
    application SIS file must first be Symbian Signed. The capabilities used in the applications
    determine, which signing option must be selected. The wrapper package must be signed using
    either the same option or a more extensive option than the application SIS.

    To package Nokia Smart Installer with the application, select the \gui {Create Smart Installer
    package} check box. This ensures that up-to-date and appropriate versions of Qt and its
    dependencies are installed on devices. Further, it reduces the file size of the application you
    publish, because you do not have to deliver the required applications.

    For more information about the Nokia Smart Installer, see the \e {Nokia Smart Installer for
    Symbian Manual}.

    Note: Nokia Smart Installer for Symbian is only available on Windows.

    \section3 Application UID

    A UID is a globally unique identifier that is used to
    uniquely identify, for example, an object or file type. In Symbian development,
    objects are identified by compound identifiers that are constructed from three
    UIDs, namely UID1, UID2, and UID3. UID1 and UID2 specify the category of an
    object, whereas UID3 identifies a particular object, such as an application.

    When you create a \gui {Mobile Qt Application}, Qt Creator adds a UID3 suitable for
    development and debugging automatically to the application .pro file. However, to
    distribute your application and get it Symbian signed, you must apply for a UID
    from Symbian Signed, which manages the allocation of UIDs. You can request UIDs either one
    at a time or as preallocated blocks on the \l{https://www.symbiansigned.com/app/page}{Symbian Signed}
    web site.

    Replace the testing UID with the distribution UID in the .pro file before you
    build the final installation package. For more information, see
    \l{http://doc.qt.nokia.com/4.7/qmake-platform-notes.html#unique-identifiers}{Unique Identifiers}.

    \section2 Specifying Run Settings for Maemo Devices

    To run an application on a Maemo device, create and select
    a device configuration in the Maemo run settings for your project.
    You can also pass command line arguments to your application.

    \image qtcreator-screenshot-run-settings.png "Run settings for Maemo devices"

    \section3 Deploying Applications to Maemo Devices

    You can specify settings for deploying applications to Maemo devices in the
    project .pro file. You can view the settings in the \gui {Run Settings}.

    The files to be installed are listed in the
    \gui {Deploy to Device} step, the \gui {Files to install} field. The
    \gui {Local File Path} field displays the location of the file on the development
    PC. The \gui {Remote Directory} field displays the folder where the file is installed on
    the device.

    \image qtcreator-maemo-deployment.png "Deploy to device"

    If you develop your own libraries, Qt Creator needs to be able to access them
    during compilation. When you install MADDE, an instance of the device file
    system, called sysroot, is installed to the development PC. Libraries are copied to
    sysroot if the \gui {Also deploy to sysroot} check box is selected.

    \section3 Creating Debian Installation Packages

    When you run the application on the \gui{Maemo} target, Qt Creator generates
    a debian installation package in the build directory by default. You can deliver
    the installation package to users for installation on Maemo devices that are of
    the same type and run the same firmware as the connected device.

    \image qtcreator-maemo-deb-package.png "Create installation package"

    The name of the installation package is displayed in the \gui {Create Package}
    field in the \gui {Run Settings}. You can change the version number in the \gui {Version number} field.

    Qt Creator provides templates for a set of files that must be included
    in debian packages. To edit the files, select a file in \gui {Adapt debian
    file} and click \gui Edit. The file opens in the text editor.

    The debian control file contains an application icon in encoded form. To add the
    application icon to the file, select it in the \gui {Package manager icon} field.
    For more information about icon files and adding them manually, see
    \l{ http://wiki.maemo.org/Packaging#Displaying_an_icon_in_the_Application_Manager_next_to_your_package}{Displaying an icon in the Application Manager next to your package}.

    \note Qt Creator automates this process for you.

    \section1 Specifying a Custom Executable to Run

    If you use cmake or the generic project type in Qt Creator, or want
    to run a custom desktop executable, create a \gui {Custom Executable}
    run configuration for your project.

    Specify the executable to run, command line arguments, working directory,
    and environment variables to use.

    \image qmldesigner-run-custom-exe.png "Run settings for custom executables"

    \section1 Specifying Run Settings for Qt Quick Projects

    Select run settings in the \gui {Run configuration} field. The settings
    are specified automatically and, you mostly need to change them if you
    develop applications that use both C++ and QML:

    \list

        \o \gui {Custom QML Viewer} is the path to the \QQV executable.
        Qt Creator ships with a specific version of \QQV and imported
        modules, which is used by default. If you develop Qt Quick applications
        that contain C++ plugins, you must select the \QQV version
        shipped with your Qt version here.

        \o \gui {QML Viewer arguments} sets arguments for running \QQV.
        The \c{-I <directory>} argument searches for C++ or QML plugins from
        the project folder. For a list of available arguments, enter \c {qml --help}
        on the command line.

        \o \gui {Main QML file} is the Qt Quick project file.

        \o \gui Debugger allows you to select the languages to debug:
        \gui{C++} and \gui QML. \gui {Debug port} is the port to access \QQV.
        You can use any free port in the registered port range.

    \endlist

    \note Opening a socket at a well-known port presents a security risk. Anyone
    on the Internet could connect to the application that you are debugging and
    execute any JavaScript functions. Therefore, you must make sure that the port
    is properly protected by a firewall.

    \title Creating a Mobile Application with Qt SDK

    \note To complete this tutorial, you must install \QSDK.
    The installation program installs and configures the necessary tool chains
    for mobile application development.

    This tutorial describes how to use Qt Creator to create a small Qt
    application, Battery Indicator, that uses the System Information
    Mobility API to fetch battery information from the device.

    \image qtcreator-batteryindicator-screenshot.png

    \section1 Creating the Battery Indicator Project

    \note Create the project with the \gui{Help} mode active so that you can follow
    these instructions while you work.

    \list 1

        \o Select \gui{File > New File or Project > Qt C++ Project > Mobile Qt
        Application > Choose}.

        \image qtcreator-new-mobile-project.png "New File or Project dialog"

        The \gui{Introduction and Project Location} dialog opens.

        \image qtcreator-mobile-intro-and-location.png "Introduction and Project Location dialog"

        \o In the \gui{Name} field, type \bold {BatteryIndicator}.

        \o In the \gui {Create in} field, enter the path for the project files. For example,
        \c {C:\Qt\examples}, and then click \gui{Next}.

        The \gui{Qt Versions} dialog opens.

        \image qtcreator-mobile-project-qt-versions.png "Qt Versions dialog"

        \o Select \gui Maemo, \gui {Qt Simulator}, and \gui {Symbian Device} targets,
        and click \gui{Next}.

        \note Targets are listed if you installed the appropriate development
        environment, for example, as part of the \QSDK. You can add targets
        later in the \gui Projects mode.

        The \gui {Application Options} dialog opens.

        \image qtcreator-mobile-project-app-options.png "Application Options dialog"

        \o In the \gui {Orientation behavior} field, determine how the application
        behaves when the orientation of the device display rotates between portrait
        and landscape, and then click \gui{Next}.

        \note Qt Creator contains a default program icon and generates a UID for testing
        the application on a device. You only need to specify the \gui {Symbian Specific}
        and \gui {Maemo Specific} settings if you deliver the application for public use.

        The \gui{Project Management} dialog opens.

        \image qtcreator-mobile-project-summary.png "Project Management dialog"

        \o Review the project settings, and click \gui{Finish} to create the project.

    \endlist

    The BatteryIndicator project now contains the following files:

    \list

        \o BatteryIndicator.pro
        \o main.cpp
        \o BatteryIndicator.svg
        \o BatteryIndicator.png
        \o BatteryIndicator.desktop
        \o deployment.pri
        \o mainwindow.cpp
        \o mainwindow.ui
        \o mainwindow.h
        \o templates for debian deployment files

    \endlist

    \image qtcreator-mobile-project-contents.png "Project contents"

    The files come with the necessary boiler plate code that you must
    modify, as described in the following sections.

    \section1 Declaring the Qt Mobility API

    To use the Qt Mobility APIs or develop applications for Symbian
    devices, you must modify the .pro file to declare the Qt Mobility APIs
    that you use.

    This example uses the System Info API, so you must declare it, as
    illustrated by the following code snippet:

    \code

    CONFIG += mobility
    MOBILITY = systeminfo

    \endcode

    Each Mobility API has its corresponding value that you have to add
    as a value of MOBILITY to use the API. For a list of the APIs and the
    corresponding values that you can assign to MOBILITY, see the
    \l {http://doc.qt.nokia.com/qtmobility-1.0/quickstart.html}{Quickstart Example}.

    \section1 Designing the User Interface

    \list 1

        \o In the \gui{Editor} mode, double-click the mainwindow.ui
        file in the \gui{Projects} view to launch the integrated \QD.

        \o Drag and drop a \gui{Progress Bar} (\l{http://doc.qt.nokia.com/4.7/qprogressbar.html}{QProgressBar})
        widget to the form.

        \image qtcreator-mobile-project-widgets.png "Adding widgets to the UI"

        \o In the \gui Properties pane, change the \gui objectName to
        \bold batteryLevelBar.

        \o Right-click the \gui MainWindow object and select
        \gui {Lay Out > Lay Out Horizontally} to ensure that the battery
        indicator widget size is adjusted correctly on Maemo devices.

    \endlist

    \section1 Completing the Header File

    The mainwindow.h file contains some of the necessary #includes, a
    constructor, a destructor, and the \c{Ui} object. You must include
    the System Info header file, add a shortcut to the mobility name
    space, and add a private function to update the battery level value in
    the indicator when the battery power level changes.

    \list 1

        \o In the \gui{Projects} view, double-click the \c{mainwindow.h} file
        to open it for editing.

        \o Include the System Info header file, as illustrated by the following
        code snippet:

        \snippet examples/batteryindicator/mainwindow.h 1

        \o Add a shortcut to the mobility name space, as illustrated by the
        following code snippet:

        \snippet examples/batteryindicator/mainwindow.h 2

        \o Declare a private function in the \c{private} section, after the
        \c{Ui::MainWindow} function, as illustrated by the following code
        snippet:

        \snippet examples/batteryindicator/mainwindow.h 3

    \endlist

    \section1 Completing the Source File

    Now that the header file is complete, move on to the source file,
    mainwindow.cpp.

    \list 1

        \o In the \gui{Projects} view, double-click the mainwindow.cpp file
        to open it for editing.

        \o Create a QSystemDeviceInfo object and set its value. Then connect the signal
        that indicates that battery level changed to the \c setValue
        slot of the progress bar. This is illustrated by the following code snippet:

        \snippet examples/batteryindicator/mainwindow.cpp 1

        \o Use the constructor to set initial values and make sure that the
         created object is in a defined state, as illustrated by the following
         code snippet:

         \snippet examples/batteryindicator/mainwindow.cpp 2

    \title Creating a Qt Quick Application

    \note To complete this tutorial, you must have Qt 4.7 or later installed.

    This tutorial uses basic elements and illustrates basic concepts of the
    \l {http://doc.qt.nokia.com/4.7/qtquick.html}{QML declarative language}.

    This tutorial describes how to use the Qt Creator to implement the
    \l{http://doc.qt.nokia.com/4.7-snapshot/declarative-animation-states.html}
    {states and transitions example application}. The example application displays a user
    icon that moves between three rectangles on the page when you click them.

    \image qmldesigner-tutorial.png "States and transitions example"

    \section1 Creating the Project

    \list 1

        \o Select \gui{File > New File or Project > Qt Quick Project > Qt Quick UI >
        Choose}.

        \o Follow the instructions of the wizard to create a project called Transitions.

        \o Press \key {Ctrl+R} to run the application in the QML Viewer.

    \endlist

    Qt Creator generates a default QML file that you can modify to create the main view
    of the application.

    \image qmldesigner-tutorial-project.png "Transitions project in Edit mode"

    \section1 Creating the Main View

    The main view of the application displays a user icon in the top left corner of the
    screen and two empty rectangles.

    To use the user.png image in your application, you must copy it to the project
    directory from the \c {\qt\examples\declarative\animation\states} directory in the
    Qt installation directory. For example:
    \c {C:\Qt\2010.05\qt\examples\declarative\animation\states}. The image appears
    in the \gui Resources pane. You can also use any other image or a QML element, instead.

    \list 1

        \o In the \gui Projects view, double-click the main .qml file (Transitions.qml)
        to open it in the code editor.

        \o Click \gui Design to open the file in \QMLD.

        \image qmldesigner-tutorial-desing-mode.png "Transitions project in Design Mode"

        \o In the \gui Navigator pane, select \gui Text and press \key Delete to delete it.

        \o Select \gui Rectangle to edit its properties.

        \image qmldesigner-tutorial-page.png "Page properties"

        \list a

            \o In the \gui Id field, enter \e page, to be able to reference the rectangle
            from other places.

            \o In the \gui Size field, set \gui W to 640 and \gui H to 480.

            \o In the \gui Colors tab, \gui Rectangle field, set the color to #343434.

        \endlist

        \o Drag and drop user.png from \gui Resources to the canvas.

        \o In the \gui Id field, enter \e userIcon.

        \image qmldesigner-tutorial-user-icon.png "User icon properties"

        \o Drag and drop a \gui Rectangle element to the canvas, and edit its properties.

        \image qmldesigner-tutorial-topleftrect.png "Rectangle properties"

        \list a

            \o In the \gui Id field, enter \e topLeftRect.

            \o In the \gui Size field, set \gui W and \gui H to 64, for the rectangle size
            to match the image size.

            \o In the \gui Colors tab, \gui Rectangle field, click the
            \inlineimage qmldesigner-transparent-button.png
            button to make the rectangle transparent.

            \o In the \gui Border field, set the border color to #808080.

            \o In the \gui Rectangle tab, \gui Border field, set the border width to
            1.

            \o In the \gui Radius field, select 6 to create rounded corners for the
            rectangle.

            \o Click \gui {Layout}, and then click the top and left anchor buttons
            to anchor the rectangle to the top left corner of the page.

            \image qmldesigner-tutorial-topleftrect-layout.png "Layout tab"

            \o In the \gui Margin field for the top anchor, select 20.

        \endlist

        \o Drag and drop a \gui {Mouse Area} element on top of the rectangle,
        and edit its properties:

        \list a

            \o Click \gui {Layout}, and then click the
            \inlineimage qmldesigner-anchor-fill-screen.png
            button to anchor the mouse area to the rectangle.

            \o In the code editor, add a pointer to a clicked expression to the mouse
            area element, as illustrated by the following code snippet:

            \code

            MouseArea {
                id: mouse_area1
                anchors.fill: parent
                onClicked: page.state = ''
            }

            \endcode

            The expression sets the state to the base state and returns the image to
            its initial position.

        \endlist

    \o To make sure that the user icon appears within the rectangle even if the screen
    size changes, you can anchor the icon to the x and y coordinates of the rectangle:

        \list a

        \o In the \gui Navigator, select userIcon.

        \o In the \gui Geometry tab, \gui {Position X} field, open the menu and select
        \gui {Set Expression}.

        \o Enter the following expression: \c {topLeftRect.x}

        \o In the \gui Y field, set the following expression: \c {topLeftRect.y}

        \endlist

    \o Copy topLeftRect (by pressing \key {Ctrl+C}) and paste it to the canvas twice
    (by pressing \key {Ctrl+V}). Qt Creator renames the new instances of the element
    topLeftRect1 and topLeftRect2.

    \o Select topLeftRect1 and edit its properties:

        \list a

            \o In the \gui Id field, enter \e middleRightRect.

            \o In \gui {Layout}, select the right and vertical center anchor buttons to
            anchor the rectangle to the middle right margin of the screen.

            \o In the code editor, modify the pointer to the clicked expression in the
            mouse area element. The following expression sets the state to \e State1:

            \c {onClicked: page.state = 'State1'}

            You will create State1 later.

        \endlist

    \o Select topLeftRect2 and edit its properties:

        \list a

            \o In the \gui Id field, enter \e bottomLeftRect.

            \o In \gui {Layout}, select the bottom and left anchor buttons to
            anchor the rectangle to the bottom left margin of the screen.

            \o In the code editor, modify the pointer to a clicked expression in the
            mouse area element. The following expression sets the state to \e State2:

            \c {onClicked: page.state = 'State2'}

            You will create State2 later.

        \endlist

    \o Press \key {Ctrl+R} to run the application in the QML Viewer.

    \endlist

    \image qmldesigner-tutorial.png "States and transitions example"

    You should see the user icon in the top left rectangle, and two additional
    rectangles in the center right and bottom left of the screen.

    You can now create additional states to add views to the application.

    \section1 Adding Views

    In the .qml file, you already created pointers to two additional states:
    State1 and State2. To create the states:

    \list 1

        \o Click the empty slot in the \gui States pane to create State1.

        \o Drag and drop the user icon on top of middleRightRect.

        \image qmldesigner-tutorial-state1.png "State 1"

        \o Click the empty slot in the \gui States pane to create State2.

        \o Drag and drop the user icon on top of bottomLeftRect.

    \o Press \key {Ctrl+R} to run the application in the QML Viewer.

    \endlist

    Click the rectangles to move the user icon from one rectangle to another.

    \section1 Adding Animation to the View

    Add transitions to define how the properties change when the user icon moves
    between states. The transitions apply animations to the user icon. For example,
    the user icon bounces back when it moves to the middleRightRect and eases into
    bottomLeftRect. Add the transitions in the code editor.

    \list 1

        \o In the code editor, add the following code to specify that when moving to
        State1, the x and y coordinates of the user icon change linearly over a duration
        of 1 second:

        \code

        transitions: [
            Transition {
                from: "*"; to: "State1"
                NumberAnimation {
                    properties: "x,y";
                    duration: 1000
                }
            },

        \endcode

        \o You can use the Qt Quick toolbar for animation to change the easing curve
        type from linear to OutBounce:

        \list a

            \o Select NumberAnimation and click
            \inlineimage qml-toolbar-indicator.png
            to open the toolbar:

            \image qmldesigner-tutorial-quick-toolbar.png "Qt Quick toolbar for animation"

            \o In the \gui Easing field, select \gui Bounce.

            \o In the \gui Subtype field, select \gui Out.

        \endlist

        \o Add the following code to specify that when moving to State2, the x and y
        coordinates of the user icon change over a duration of 2 seconds,
        and an InOutQuad easing function is used:

        \code

        Transition {
            from: "*"; to: "State2"
            NumberAnimation {
                properties: "x,y";
                easing.type: Easing.InOutQuad;
                duration: 2000
            }
        },

        \endcode

        \o Add the following code to specify that for any other state changes, the x
        and y coordinates of the user icon change linearly over a duration of 200
        milliseconds:

        \code

        Transition {
            NumberAnimation {
                properties: "x,y";
                duration: 200
            }
        }

        \endcode

        \o Press \key {Ctrl+R} to run the application in the QML Viewer.

    \endlist

    Click the rectangles to view the animated transitions.

    \section1 Deploying the Application to Mobile Devices

    To deploy the application to mobile devices, use the \gui {Qt Quick Application} wizard
    to convert it into a Qt Quick application. For more information, see

    \title Creating a Qt C++ Application

    This tutorial describes how to use Qt Creator
    to create a small Qt application, Text Finder. It is a simplified version of the
    QtUiTools \l{http://doc.qt.nokia.com/4.7/uitools-textfinder.html}{Text Finder}
    example.

    \image qtcreator-textfinder-screenshot.png

    \section1 Creating the Text Finder Project

    \note Create the project with two instances of Qt Creator open and the \gui{Help} mode
    active in one of them so that you can follow
    these instructions while you work.

    \list 1

        \o Select \gui{File > New File or Project > Qt C++ Project > Qt Gui
        Application > Choose}.

           \image qtcreator-new-project.png "New File or Project dialog"

        The \gui{Introduction and Project Location} dialog opens.

        \image qtcreator-intro-and-location.png "Introduction and Project Location dialog"

        \o In the \gui{Name} field, type \bold {TextFinder}.


        \o In the \gui {Create in} field, enter the path for the project files. For example,
        \c {C:\Qt\examples}, and then click \gui{Next}.

        The \gui {Qt Versions} dialog opens.

        \image qtcreator-new-project-qt-versions.png "Qt Versions dialog"

        \o Select the Qt versions to use as build targets for your project, and click
        \gui{Next}.

        \note If you have only one Qt version installed, this dialog is skipped.

        The \gui{Class Information} dialog opens.

        \image qtcreator-class-info.png "Class Information dialog"

        \o In the \gui{Class name} field, type \bold {TextFinder} as the class name.

        \o In the \gui{Base class} list, select \bold {QWidget} as the base class type.

           \note The \gui{Header file}, \gui{Source file} and
           \gui{Form file} fields are automatically updated to match the name of the
           class.

        \o Click \gui{Next}.

        The \gui{Project Management} dialog opens.

        \image qtcreator-new-project-summary.png "Project Management dialog"

        \o Review the project settings, and click \gui{Finish} to create the project.


    \endlist



    The TextFinder project now contains the following files:

    \list
        \o textfinder.h
        \o textfinder.cpp
        \o main.cpp
        \o textfinder.ui
        \o textfinder.pro
    \endlist

    \image qtcreator-textfinder-contents.png "TextFinder project contents"

    The .h and .cpp files come with the necessary boiler plate code.
    The .pro file is complete.

    \section1 Filling in the Missing Pieces

    Begin by designing the user interface and then move on to filling
    in the missing code. Finally, add the find functionality.

    \section2 Designing the User Interface

    \image qtcreator-textfinder-ui.png "Text Finder UI"

    \list 1

    \o In the \gui{Editor} mode, double-click the textfinder.ui file in the \gui{Projects}
    view to launch the integrated \QD.

    \o Drag and drop the following widgets to the form:

    \list
    \o \gui{Label} (QLabel)
    \o \gui{Line Edit} (QLineEdit)
    \o \gui{Push Button} (QPushButton)

    \endlist

    \image qtcreator-textfinder-ui-widgets.png "Adding widgets to Text Finder UI"

    \note To easily locate the widgets, use the search box at the top of the
    \gui Sidebar. For example, to find the \gui Label widget, start typing
    the word \bold label.

    \image qtcreator-texfinder-filter.png "Filter field"

    \o Double-click the \gui{Label} widget and enter the text \bold{Keyword}.

    \o Double-click the \gui{Push Button} widget and enter the text \bold{Find}.

    \o In the \gui Properties pane, change the \gui objectName to \bold findButton.

    \image qtcreator-textfinder-objectname.png "Changing object names"

    \o Press \key {Ctrl+A} to select the widgets and click \gui{Lay out Horizontally}
    (or press \gui{Ctrl+H}) to apply a horizontal layout
    (QHBoxLayout).

    \image qtcreator-texfinder-ui-horizontal-layout.png "Applying horizontal layout"

    \o Drag and drop a \gui{Text Edit} widget (QTextEdit)
    to the form.

    \o Select the screen area and click \gui{Lay out Vertically} (or press \gui{Ctrl+L})
    to apply a vertical layout (QVBoxLayout).

    \image qtcreator-textfinder-ui.png "Text Finder UI"

    Applying the horizontal and vertical layouts ensures that the application UI scales to different
    screen sizes.

    \o To call a find function when users press the \gui Find button, you use the Qt signals
    and slots mechanism. A signal is emitted when a particular event occurs and a slot is
    a function that is called in response to a particular signal. Qt widgets have predefined
    signals and slots that you can use directly from \QD. To add a slot for the find function:

        \list

            \o Right-click the \gui Find button to open a context-menu.
            \o Select \gui {Go to Slot > clicked()}, and then select \gui OK.

            A private slot, \c{on_findButton_clicked()}, is added to the header file,
            textfinder.h and a private function, \c{TextFinder::on_findButton_clicked()},
            is added to the source file, textfinder.cpp.

        \endlist

    \o Press \gui{Ctrl+S} to save your changes.

    \endlist

    For more information about designing forms with \QD, see the
    \l{http://doc.qt.nokia.com/4.7/designer-manual.html}{Qt Designer Manual}.

    \section2 Completing the Header File

    The textfinder.h file already has the necessary #includes, a
    constructor, a destructor, and the \c{Ui} object. You need to add a private
    function, \c{loadTextFile()}, to read and display the
    contents of the input text file in the
    QTextEdit.

    \list 1

    \o In the \gui{Projects} pane in the \gui {Edit view}, double-click the \c{textfinder.h} file
    to open it for editing.

    \o Add a private function
    to the \c{private} section, after the \c{Ui::TextFinder} pointer, as
    illustrated by the following code snippet:

    \snippet examples/textfinder/textfinder.h 0

    \endlist

    \section2 Completing the Source File

    Now that the header file is complete, move on to the source file,
   textfinder.cpp.

    \list 1

    \o In the \gui{Projects} pane in the \gui Edit view, double-click the textfinder.cpp file
    to open it for editing.

    \o Add code to load a text file using
    QFile, read it with QTextStream, and
    then display it on \c{textEdit} with
    \l{http://doc.qt.nokia.com/4.7/qtextedit.html#plainText-prop}{setPlainText()}.
    This is illustrated by the following code snippet:

    \snippet examples/textfinder/textfinder.cpp 0

    \o To use QFile and QTextStream, add the
    following #includes to textfinder.cpp:

    \snippet examples/textfinder/textfinder.cpp 1

    \o For the \c{on_findButton_clicked()} slot, add code to extract the search string and
    use the \l{http://doc.qt.nokia.com/4.7/qtextedit.html#find}{find()} function
    to look for the search string within the text file. This is illustrated by
    the following code snippet:

    \snippet examples/textfinder/textfinder.cpp 2

    \o Once both of these functions are complete, add a line to call \c{loadTextFile()} in
    the constructor, as illustrated by the following code snippet:

    \snippet examples/textfinder/textfinder.cpp 3

    \endlist

    The \c{on_findButton_clicked()} slot is called automatically in
    the uic generated ui_textfinder.h file by this line of code:

    \code
    QMetaObject::connectSlotsByName(TextFinder);

    \section2 Creating a Resource File

    You need a resource file (.qrc) within which you embed the input
    text file. The input file can be any .txt file with a paragraph of text.
    Create a text file called input.txt and store it in the textfinder
    folder.

    To add a resource file:
    \list 1
        \o Select \gui{File > New File or Project > Qt > Qt Resource File > Choose}.
    \image qtcreator-add-resource-wizard.png "New File or Project dialog"

    The \gui {Choose the Location} dialog opens.

        \image qtcreator-add-resource-wizard2.png "Choose the Location dialog"

        \o In the \gui{Name} field, enter \bold{textfinder}.
        \o In the \gui{Path} field, enter \c{C:\Qt\examples\TextFinder},
        and click \gui{Next}.

        The \gui{Project Management} dialog opens.

        \image qtcreator-add-resource-wizard3.png "Project Management dialog"


        \o In the \gui{Add to project} field, select \bold{TextFinder.pro}
        and click \gui{Finish} to open the file in the code editor.

        \o Select \gui{Add > Add Prefix}.
        \o In the \gui{Prefix} field, replace the default prefix with a slash (/).
        \o Select \gui{Add > Add Files}, to locate and add input.txt.

    \title Using Version Control Systems

    Version control systems supported by Qt Creator are:
    \table
        \header
            \i \bold{Version Control System}
            \i \bold{Address}
            \i \bold{Notes}
        \row
            \i  \bold{Git}
            \i  \l{http://git-scm.com/}
            \i
        \row
            \i  \bold{Subversion}
            \i  \l{http://subversion.tigris.org/}
            \i
        \row
            \i  \bold{Perforce}
            \i  \l{http://www.perforce.com}
            \i  Server version 2006.1 and later
        \row
            \i  \bold{CVS}
            \i  \l{http://www.cvshome.org}
            \i
        \row
            \i  \bold{Mercurial}
            \i  \l{http://mercurial.selenic.com/}
            \i  Qt Creator 2.0 and later
    \endtable


    \section1 Setting Up Version Control Systems

    Qt Creator uses the version control system's command line clients to access
    your repositories. To allow access, make sure that the command line clients
    can be located using the \c{PATH} environment variable or specify the path to
    the command line client executables in \gui{Tools} > \gui{Options...} >
    \gui {Version Control}.

    After you set up the version control system, use the command line to check
    that everything works (for example, use the status command). If no issues arise,
    you should be ready to use the system also from Qt Creator.

    \section2 Using msysGit on Windows

    If you configure Git for use with \c {git bash}, only, and use SSH
    authorization, Git looks for the SSH keys in the directory where the
    \c HOME environment points to. The variable is always set by \c {git bash}.

    However, the variable is typically not set in a Windows command prompt.
    When you run Git from a Windows command prompt, it looks for the SSH keys in its
    installation directory, and therefore, the authorization fails.

    You can set the \c HOME environment variable from Qt Creator. Select \gui {Tools >
    Options... > Version Control > Git}. Select the \gui {Environment Variables}
    and the \gui {Set "HOME" environment variable} check boxes. \c HOME is set to
    \c %HOMEDRIVE%%HOMEPATH% when the Git executable is run and authorization works
    as it would with \c {git bash}.

    \section1 Setting Up Common Options

    Select \gui{Tools} > \gui{Options...} > \gui{Version Control} > \gui{Common}
    to specify settings for submit messages:
    \list
       \o   \gui{Submit message check script} is a script or program that
             can be used to perform checks on the submit message before
             submitting. The submit message is passed in as the script's first
             parameter. If there is an error, the script should output a
             message on standard error and return a non-zero exit code.

       \o    \gui{User/alias configuration file} takes a file in mailmap format
             that lists user names and aliases. For example:

             \code
             Jon Doe <Jon.Doe@company.com>
             Hans Mustermann <Hans.Mustermann@company.com> hm <info@company.com>
             \endcode

             \note The second line above specifies the alias \e{hm} and the
             corresponding email address for \e{Hans Mustermann}. If the
             user/alias configuration file is present, the submit editor
             displays a context menu with \gui{Insert name...} that pops up a
             dialog letting the user select a name.

       \o    \gui{User fields configuration file} is a simple text file
             consisting of lines specifying submit message fields that take
             user names, for example:

             \code
             Reviewed-by:
             Signed-off-by:
             \endcode
    \endlist

    The fields above appear below the submit message. They provide completion
    for the aliases/public user names specified in the
    \e{User/alias configuration file} as well as a button that opens the
    aforementioned user name dialog.

    \section1 Creating VCS Repositories for New Projects

    Qt Creator allows for creating VCS repositories for version
    control systems that support local repository creation, such as
    Git or Mercurial.
    When creating a new project by selecting \gui File >
    \gui{New File or Project...}, you can choose a version
    control system in the final wizard page.

    \section1 Using Version Control Systems

    The \gui{Tools} menu contains a submenu for each supported version
    control system.

    The \gui{Version Control} output pane displays the commands
    that are executed, a timestamp, and the relevant output.
    Select \gui {Window > Output Panes > Version Control} to open
    the pane.


    \image qtcreator-vcs-pane.png


    \section2 Adding Files

    When you create a new file or a new project, the wizard displays a page
    asking whether the files should be added to a version control system.
    This happens when the parent directory or the project is already
    under version control and the system supports the concept of adding files,
    for example, Perforce and Subversion. Alternatively, you can
    add files later by using the version control tool menus.

    With Git, there is no concept of adding files. Instead, all modified
    files must be staged for a commit.


    \section2 Viewing Diff Output

    All version control systems provide menu options to \e{diff} the current
    file or project: to compare it with the latest version stored in the
    repository and to display the differences. In Qt Creator, a diff is
    displayed in a read-only editor. If the file is accessible, you can
    double-click on a selected diff chunk and Qt Creator opens an editor
    displaying the file, scrolled to the line in question.

    \image qtcreator-vcs-diff.png


    \section2 Viewing Versioning History and Change Details

    Display the versioning history of a file by selecting \gui{Log}
    (for Git and Mercurial) or \gui{Filelog} (for CVS, Perforce, and
    Subversion). Typically, the log output contains the date, the commit
    message, and a change or revision identifier. Click on the identifier to
    display a description of the change including the diff.
    Right-clicking on an identifier brings up a context menu that lets you
    show annotation views of previous versions (see \l{Annotating Files}).

    \image qtcreator-vcs-log.png


    \section2 Annotating Files

    Annotation views are obtained by selecting \gui{Annotate} or \gui{Blame}.
    Selecting \gui{Annotate} or \gui{Blame} displays the lines of the file
    prepended by the change identifier they originate from. Clicking on the
    change identifier shows a detailed description of the change.

    To show the annotation of a previous version, right-click on the
    version identifier at the beginning of a line and choose one of the
    revisions shown at the bottom of the context menu. This allows you to
    navigate through the history of the file and obtain previous versions of
    it. It also works for Git and Mercurial using SHA's.

    The same context menu is available when right-clicking on a version
    identifier in the file log view of a single file.


    \section2 Committing Changes

    Once you have finished making changes, submit them to the version control
    system by choosing \gui{Commit} or \gui{Submit}. Qt Creator displays a
    commit page containing a text editor where you can enter your commit
    message and a checkable list of modified files to be included.

    \image qtcreator-vcs-commit.png

    When you have finished filling out the commit page information, click on
    \gui{Commit} to start committing.

    The \gui{Diff Selected Files} button brings up a diff view of the
    files selected in the file list. Since the commit page is just another
    editor, you can go back to it by closing the diff view. You can also check
    a diff view from the editor combo box showing the \gui{Opened files}.

    \section2 Reverting Changes

    All supported version control system support reverting your project to
    known states. This functionality is generally called \e reverting.

    The changes discarded depend on the version control system.

    A version control system can replace the \gui Revert menu option with other
    options.

    \section3 Reverting Changes Using Git

    The Git version control system has an index that is used to stage
    changes. The index is commited on the next commit. Git allows you to revert
    back to the state of the last commit as well as to the state staged in the
    index.

    \list

        \o \gui{Undo Unstaged Changes} reverts all changes and resets the working
        directory to the state of the index.

        \o \gui{Undo Uncommitted Changes} reverts all changes, discarding the index.
        This returns your working copy to the state it was in right after the last commit.

    \endlist

    \section2 Using Additional Git Functions

    Git is a fast decentralized version control system. Git is available
    for Windows, Linux and Mac.

    The \gui Git submenu contains the following additional items:

    \table

        \row
            \i  \gui {Patch > Apply from Editor/Apply from File...}
            \i  Patches are rewriting instructions that can be applied to a set of files.
                You can either apply a patch file that is open in Qt Creator or select
                the patch file to apply from the file system.
        \row
            \i  \gui{Pull}
            \i  Pull changes from the remote repository. If there are locally
                modified files, you are prompted to stash those changes. Select \gui{Tools >
                Options... > Version Control > Git} and select the \gui {Pull with rebase}
                check box to perform a rebase operation while pulling.

        \row
            \i  \gui{Clean.../Clean Project...}
            \i  All files that are not under version control (with the exception
                of patches and project files) are displayed in the \gui {Clean Repository}
                dialog. Select the files to delete and click \gui Delete. This allows you to
                clean a build completely.

        \row
            \i  \gui{Branches...}
            \i  Display the \gui Branch dialog that shows the local branches at the
                top and remote branches at the bottom. To switch to a local branch,
                double-click it. Double-clicking on a remote branch first creates a local
                branch with the same name that tracks the remote branch, and then switches
                to it.

                \image qtcreator-vcs-gitbranch.png

        \row
            \i  \gui {Stage File for Commit}
            \i  Mark new or modified files for committing to the repository.
                To undo this function, select \gui {Unstage File from Commit}.
        \row
            \i  \gui{Show Commit...}
            \i  Select a commit to view. Enter the SHA of the commit
                in the \gui Change field.
    \endtable

    \section3 Using Stashes

    With Git, you can put your current set of changes onto a virtual shelf called a \e stash.
    Stashes are useful, for example, to put aside a set of changes to work on higher
    priority tasks or to pull in new chages from another repository.

    Qt Creator exposes this functionality in the \gui{Tools > Git > Stash} menu.

    \table
        \row
            \i  \gui{Stashes...}
            \i  Display a dialog that shows all known stashes with options to restore,
                display or delete them.
        \row
            \i  \gui{Stash}
            \i  Stash all local changes. The working copy is then reset to
                the state it had right after the last commit.
        \row
            \i  \gui{Stash Snapshot...}
            \i  Save a snapshot of your current work under a name for later reference. The
                working copy is unchanged.

                For example, if you want to try something and find out later that it does not work,
                you can discard it and return to the state of the snapshot.
        \row
            \i  \gui{Stash Pop}
            \i  Remove a single stashed state from the stash list and apply it on
                top of the current working tree state.
    \endtable

    \section2 Using Additional Mercurial Functionality

    The \gui Mercurial submenu contains the following additional items:

    \table
        \row
            \i  \gui{Import}
            \i  Apply changes from a patch file.
        \row
            \i  \gui{Incoming}
            \i  Monitor the status of a remote repository by listing
                the changes that will be pulled.
        \row
            \i  \gui{Outgoing}
            \i  Monitor the status of a remote repository by listing
                the changes that will be pushed.
        \row
            \i  \gui{Pull}
            \i  Pull changes from the remote repository.
        \row
            \i  \gui{Update}
            \i  Look at an earlier version of the code.
    \endtable

    \section2 Using Additional Perforce Functions

    When you start Qt Creator, it looks for the executable specified
    in the \gui{P4 command} field in \gui{Tools > Options... > Version
    Control > Perforce}. If you do not use Perforce and want to turn
    off the check, clear this field.

    The \gui Perforce submenu contains the following additional items:

    \table
        \row
            \i  \gui{Describe...}
            \i  View information about changelists and the files in them.
        \row
            \i  \gui{Edit File}
            \i  Open a file for editing.
        \row
            \i  \gui{Opened}
            \i  List files that are open for editing.
        \row
            \i  \gui{Pending Changes...}
            \i  Group files for commit.
        \row
            \i  \gui{Update All/Update Current Project}
            \i  Fetch the current version of the current project or all
            projects from the repository.

    \endtable

    \section2 Using Additional Subversion Functions

    The \gui Subversion submenu contains the following additional items:

    \table
        \row
            \i  \gui{Describe...}
            \i  Display commit log messages for a revision.
        \row
            \i  \gui{Update Project/Update Repository}
            \i  Update your working copy.
    \endtable

    \title Searching With the Locator

    The locator provides one of the easiest ways in Qt Creator to browse
    through projects, files, classes, methods, documentation and file systems.
    You can find the locator in the bottom left of the Qt Creator window.

    To activate the locator, press \key Ctrl+K (\key Cmd+K on Mac OS
    X) or select \gui Tools > \gui Locate....

    \image qtcreator-locator.png

    To edit the currently open project's main.cpp file using the locator:
    \list 1
        \o Activate the locator by pressing \key Ctrl+K.
        \o Enter \tt{main.cpp}.

           \image qtcreator-locator-open.png
        \o Press \key Return.

           The main.cpp file opens in the editor.
    \endlist

    It is also possible to enter only a part of a search string.
    As you type, the locator shows the occurrences of that string regardless
    of where in the name of an component it appears.

    To narrow down the search results, you can use the following wildcard
    characters:
    \list
        \o To match any number of any or no characters, enter \bold{*}.
        \o To match a single instance of any character, enter \bold{?}.
    \endlist

    \section1 Using the Locator Filters

    The locator allows you to browse not only files, but any items
    defined by \bold{locator filters}. By default, the locator contains
    filters which locate:
    \list
        \o  Any open document
        \o  Files anywhere on your file system
        \o  Files belonging to your project, such as source, header resource,
            and .ui files
        \o  Class and method definitions in your project or anywhere referenced
            from your project
        \o  Help topics, including Qt documentation
        \o  Specific line in the document displayed in your editor
    \endlist

    To use a specific locator filter, type the assigned prefix followed by
    \key Space. The prefix is usually a single character.

    For example, to locate symbols matching
    QDataStream:
    \list 1
        \o Activate the locator.
        \o Enter \tt{\bold{: QDataStream}} (: (colon) followed by a
           \key Space and the symbol name (QDataStream)).

           The locator lists the results.

           \image qtcreator-navigate-popup.png
    \endlist

    By default the following filters are enabled and you do not need to use
    their prefixes explicitly:
    \list
        \o Going to a line in the current file (l).
        \o Going to an open file (o).
        \o Going to a file in any open project (a).
    \endlist

    \section2 Using the Default Locator Filters

    The following locator filters are available by default:

    \table
        \header
            \o  Function
            \o  Enter in locator
            \o  Example
        \row
            \o  Go to a line in the current file.
            \o  \tt{\bold{l \e{Line number}}}
            \o  \image qtcreator-locator-line.png
        \row
            \o  Go to a symbol definition.
            \o  \tt{\bold{: \e{Symbol name}}}
            \o  \image qtcreator-locator-symbols.png
        \row
            \o  Go to a help topic.
            \o  \tt{\bold{? \e{Help topic}}}
            \o  \image qtcreator-locator-help.png
        \row
            \o  Go to an open file.
            \o  \tt{\bold{o \e{File name}}}
            \o  \image qtcreator-locator-opendocs.png
        \row
            \o  Go to a file in the file system (browse the file system).
            \o  \tt{\bold{f \e{File name}}}
            \o  \image qtcreator-locator-filesystem.png
        \row
            \o  Go to a file in any project currently open.
            \o  \tt{\bold{a \e{File name}}}
            \o  \image qtcreator-locator-files.png
        \row
            \o  Go to a file in the current project.
            \o  \tt{\bold{p \e{File name}}}
            \o  \image qtcreator-locator-current-project.png
        \row
            \o  Go to a class definition.
            \o  \tt{\bold{c \e{Class name}}}
            \o  \image qtcreator-locator-classes.png
        \row
            \o  Go to a method definition.
            \o  \tt{\bold{m \e{Method name}}}
            \o  \image qtcreator-locator-methods.png
    \endtable

    \section2 Creating Locator Filters

    To quickly access files not directly mentioned in your project, you can
    create your own locator filters. That way you can locate files in a
    directory structure you have defined.

    To create a locator filter:
    \list 1
        \o In the locator, click \inlineimage qtcreator-locator-magnify.png
           and select \gui Configure.... to open the \gui Locator options.

           \image qtcreator-locator-customize.png

        \o Click \gui Add.
        \o In the \gui{Filter Configuration} dialog:
        \list
            \o Name your filter.
            \o Select at least one directory. The locator searches directories
               recursively.
            \o Define the file pattern as a comma separated list. For example,
               to search all .h and .cpp files, enter \bold{*.h,*.cpp}
            \o Specify the prefix string.

               To show only results matching this filter, select
               \gui{Limit to prefix}.

               \image qtcreator-navigate-customfilter.png
        \endlist
        \o Click OK.
    \endlist

    \section3 Configuring the Locator Cache

    The locator searches the files matching your file pattern in the
    directories you have selected and caches that information. The cache for
    all default filters is updated as you write your code. By default,
    Qt Creator updates the filters created by you once an hour.

    To update the cached information manually, click
    \inlineimage qtcreator-locator-magnify.png
    and select \gui Refresh.

    To set a new cache update time:
    \list 1
        \o Select \gui Tools > \gui Options... > \gui Locator.
        \o In \gui{Refresh interval}, define new time in minutes.
    \endlist

    \title Managing Sessions

    When you exit Qt Creator, a snapshot of your current workspace is stored
    as a \e session. A session is an arbitrary collection of:

    \list
        \o Open projects with their dependencies (including SUBDIRS projects)
        \o Open editors
        \o Breakpoints and watches
        \o Bookmarks
    \endlist

    A session is  personal, that is, not meant to be shared. It is not
    supposed to reflect the project structure. It contains personal data, such as
    bookmarks and breakpoints that are usually not of interest to other developers
    working on the same projects.

    For example, if you work on a project and need to switch to another project for a
    while, you can save your workspace as a session. This makes it easier
    to return to working on the first project later.

    To create a new session or remove existing sessions, select \gui File >
    \gui Sessions > \gui{Session Manager}.

    \image qtcreator-session-manager.png

    To switch between sessions, choose
    \gui File > \gui Session. If you do not create or select a session,
    Qt Creator always uses the default session, which was created the
    last time you exited Qt Creator.

    When you launch Qt Creator, a list of existing sessions is displayed on the
    \gui{Welcome screen}.

    \title Debugging

    Qt Creator does not include a debugger. It provides a debugger plugin that acts
    as an interface between the Qt Creator core and external native debuggers
    such as the GNU Symbolic Debugger (gdb), the Microsoft Console Debugger (CDB),
    and a QML/JavaScript debugger.

    The following sections describe debugging with Qt Creator:

    \list

        \o \l{Debugging the Example Application} uses an example application to illustrate
        how to debug Qt C++ applications in the \gui Debug mode.

        \o \l{Interacting with the Debugger} describes the views and functions available
        in the \gui Debug mode.

        \o \l{Setting Up Debugger} summarizes the support for debugging C++ code and
        requirements for installation. Typically, the interaction between Qt Creator
        and the native debugger is set up automatically and you do not need to do anything.

        \o \l{Debugger Modes of Operation} describes the operating modes in which the
        debugger plugin runs, depending on where and how the process is started and run.

        \o \l{Using Debugging Helpers} describes how to get more detailed data
        on complex data.

        \o \l{Debugging Qt Quick Projects} describes how to debug Qt Quick projects.

    \title Debugger Modes of Operation

    The debugger plugin runs in different operating modes depending on where and
    how the process is started and run. Some of the modes are only available for
    a particular operating system or platform.

    You can launch the debugger in the following modes:

    \list

       \o \bold Plain to debug locally started applications, such as a
        Qt based GUI application.

       \o \bold Terminal to debug locally started processes that need a
       console, typically without a GUI.

       \o \bold Attach to debug local processes started outside Qt Creator.

       \o \bold Remote to debug a process running on a different machine.

       \o \bold Core to debug crashed processes on Unix.

       \o \bold Post-mortem to debug crashed processes on Windows.

       \o \bold TRK to debug processes running on a Symbian device.

    \endlist

    \note Debugging QML and JavaScript is supported only in plain mode.

    When you click the \gui {Start Debugging} button, the debugger is launched
    in the appropriate operating mode (plain, terminal, or TRK), based on the
    build and run settings for the active project. Select \gui Debug menu options
    to launch the debugger in the other modes.

    \section2 Plain Mode

    To launch the debugger in the plain mode, click the \gui {Start Debugging}
    button for the active project, or choose
    \gui {Debug > Start Debugging > Start and Debug External Application...}
    and specify an executable.

    \section2 Terminal Mode

    To launch the debugger in the terminal mode, select \gui {Projects > Run Settings}
    and select the \gui {Run in terminal} check box. Then click the
    \gui {Start Debugging} button for the active project.

    \section2 Attach Mode

    To launch the debugger in the attach mode, select
    \gui {Debug > Start Debugging >  Attach to Running External Application...},
    and then select a process by its name or process ID to attach to.

    \section2 Remote Mode

    The remote mode uses a \e{gdbserver} daemon that runs on the remote machine.

    To launch the debugger in the remote mode, select
    \gui {Debug > Start Debugging > Start and Attach to Remote Application...}.

    \section2 Core Mode

    The core mode is available only in Unix. It debugs crashed processes using
    the \e {core} files (crash dumps) that are generated if the setting
    is enabled in the shell.

    To enable the dumping of core files, enter the following command in the
    shell from which the application will be launched:

    \code
    ulimit -c unlimited
    \endcode

    To launch the debugger in the core mode, select
    \gui{Debug > Start Debugging >  Attach to Core...}.

    \section2 Post-Mortem Mode

    The post-mortem mode is available only on Windows, if you have installed
    the debugging tools for Windows.

    The Qt Creator installation program asks you whether you want to
    register Qt Creator as a post-mortem debugger. To change the setting, select
    \gui{Tools > Options...  > Debugger > Common > Use Creator for post-mortem debugging}.

    You can launch the debugger in the post-mortem mode if an application crashes
    on Windows. Click the \gui {Debug in Qt Creator} button in the error message
    that is displayed by the Windows operating system.

    \section2 TRK Mode

    The TRK mode is a special mode available only for Symbian. It
    debugs processes running on a Symbian
    device using the App TRK application that runs on the device.

    To launch the debugger in the TRK mode, open the project, select Symbian as the
    target, and click the \gui {Start Debugging} button.

    For more information on setting up Symbian projects, see
    \l{Setting Up Development Environment for Symbian}.

    \title Setting Up Debugger

    \note The information in this section applies only to debugging the C++
    language.

    Typically, the interaction between Qt Creator and the native debugger is set
    up automatically and you do not need to do anything. However, you might have an
    unsupported gdb version installed, your Linux environment might not have gdb
    installed at all, or you might want to use the debugging tools for Windows.

    \note To use the debugging tools for Windows, you must install them and add the
    Symbol Server provided by Microsoft to the symbol search path of the debugger.
    For more information, see \l{Setting the Symbol Server in Windows}.

    This section explains the
    options you have for debugging C++ code and provides installation notes for the
    supported native debuggers.

    \section1 Supported Native Debugger Versions

    The debugger plugin supports different builds of the gdb debugger, both
    with and without the ability to use Python scripting. The Python enabled
    versions are preferred, but they are not available on Mac and on older
    versions of Linux.
    On Windows, Symbian, and Maemo, only the Python version is supported.

    The non-Python versions use the compiled version of the debugging helpers,
    that you must enable separately. For more information, see
    \l{Debugging Helpers Based on C++}.

    The Python version uses a script version of the debugging helpers
    that does not need any special setup.

    The CDB native debugger has similar funtionality to the non-Python gdb debugger
    engine. Specifically, it also uses compiled C++ code for the debugging
    helper library.

    The following table summarizes the support for debugging C++ code:

    \section2 Gdb Adapter Modes

    [Advanced Topic]

    The gdb native debugger used internally by the debugger plugin runs in
    different adapter modes to cope with the variety
    of supported platforms and environments. All gdb adapters inherit from
    AbstractGdbAdapter:

    \list

       \o PlainGdbAdapter debugs locally started GUI processes.
       It is physically split into parts that are relevant only when Python is
       available, parts relevant only when Python is not available, and mixed code.

       \o TermGdbAdapter debugs locally started processes that need a
       console.

       \o AttachGdbAdapter debugs local processes started outside Qt Creator.

       \o CoreGdbAdapter debugs core files generated from crashes.

       \o RemoteGdbAdapter interacts with the gdbserver running on Linux.

       \o TrkGdbAdapter interacts with Symbian devices. The gdb protocol and
       the gdb serial protocol are used between gdb and the adapter. The TRK
       protocol is used between the adapter and AppTRK running on the device.

     \endlist

     \endomit

    \section1 Installing Native Debuggers

    There are various reasons why the debugger plugin may fail to automatically
    pick up a suitable native debugger. The native debugger might be missing
    (which is usually the case for the CDB debugger on Windows which always
    needs to be installed manually by the user) or the installed version is not
    supported.
    Check the table below for the supported versions and other important
    information about installing native debuggers.

    \table
        \header
            \o Native Debugger
            \o Notes
        \row
            \o Gdb
            \o On Linux, install version 6.8, 7.0.1 (version 7.0 is not supported),
            7.1, or later. On Mac OS X, install Apple gdb version 6.3.50-20050815
            (build 1344) or later.

        \row
            \o Debugging tools for Windows
            \o Using this engine requires you to install the
               \e{Debugging tools for Windows}
               \l{http://www.microsoft.com/whdc/devtools/debugging/installx86.Mspx}{32-bit}
               or
               \l{http://www.microsoft.com/whdc/devtools/debugging/install64bit.Mspx}{64-bit}
               package (Version 6.11.1.404 for the 32-bit or the 64-bit version of Qt Creator, respectively),
               which is freely available for download from the
               \l{http://msdn.microsoft.com/en-us/default.aspx}
               {Microsoft Developer Network}. The Qt Creator help browser does
               not allow you to download files, and therefore, you must copy the above links to
               a browser.

               \note Visual Studio does not include the Debugging tools needed,
               and therefore, you must install them separately.

               The pre-built \QSDK for Windows makes use
               of the library if it is present on the system. When manually building Qt
               Creator using the Microsoft Visual C++ Compiler, the build process checks
               for the required files in \c{"%ProgramFiles%\Debugging Tools for Windows"}.

               It is highly recommended that you add the Symbol Server provided by Microsoft to the symbol
               search path of the debugger. The Symbol Server provides you
               with debugging informaton for the operating system libraries for debugging
               Windows applications. For more information, see
               \l{Setting the Symbol Server in Windows}.

       \row
           \o Debugging tools for Mac OS X
           \o The Qt binary distribution contains both debug and release
              variants of the libraries. But you have to explicitly tell the
              runtime linker that you want to use the debug libraries even if
              your application is compiled as debug as release is the default
              library.

              If you use a qmake based project in Qt Creator,  you can set a
              flag in your run configuration, in \gui Projects mode. In the run
              configuration, select \gui{Use debug version of frameworks}.

              For more detailed information about debugging on the Mac, see:
              \l http://developer.apple.com/mac/library/technotes/tn2004/tn2124.html

        \note The Mac OS X Snow Leopard (10.6) has a bug, that can be worked
              around as described in the link provided below:
              \l http://bugreports.qt.nokia.com/browse/QTBUG-4962.

    \endtable

    \section1 Setting the Symbol Server in Windows

    To obtain debugging information for the operating system libraries for
    debugging Windows applications, add the Symbol Server provided
    by Microsoft to the symbol search path of the debugger:
    \list 1
        \o  Select \gui Tools > \gui{Options...} > \gui Debugger > \gui Cdb.
        \o  In the \gui {Symbol paths} field, open the \gui{Insert...} menu
            and select \gui{Symbol Server...}.
        \o  Select a directory where you want to store the cached information
            and click \gui OK.

            Use a subfolder in a temporary directory, such as
            \c {C:\temp\symbolcache}.
    \endlist

    \note Populating the cache might take a long time on a slow network
    connection.

    \note The first time you start debugging by using the
    Debugging tools for Windows, Qt Creator prompts you to add the Symbol
    Server.

    \title Interacting with the Debugger

    In \gui Debug mode, you can use several views to interact with the
    program you are debugging. The availability of views depends on whether
    you are debugging C++ or QML. Frequently used views are shown by
    default and rarely used ones are hidden. To change the default settings,
    select \gui {Window > Views}, and then select views to display or hide.

    \image qtcreator-debugger-views.png "Debug mode views"

    By default, the views are locked into place in the workspace. Select
    \gui {Window > Views > Locked} to unlock the views. Drag and drop the
    views into new positions on the screen. Drag view borders to resize the
    views. The size and position of views are saved for future sessions.

    \section1 Starting the Debugger

    To start a program under the debugger's control, select \gui{Debug} >
    \gui{Start Debugging} > \gui{Start Debugging}, or press \key{F5}.
    Qt Creator checks whether the compiled program is up-to-date, rebuilding
    it if necessary. The debugger then takes over and starts the program.

    \note Starting a program in the debugger can take a considerable amount of
    time, typically in the range of several seconds to minutes if complex
    features (like QtWebKit) are used.

    The debugger is launched in the appropriate operating mode (plain, terminal,
    or TRK), based on the build and run settings for the active project.
    Select \gui Debug menu options to launch the debugger in other modes.
    For more information, see \l{Debugger Modes of Operation}.

    \note Debugging QML and JavaScript is supported only in plain mode.

    Once the program starts running, it behaves and performs as usual.
    You can interrupt a running C++ program by selecting \gui{Debug} >
    \gui {Interrupt}. The program is automatically interrupted as soon as a
    breakpoint is hit.

    \section1 Using the Debugger

    Once the program stops, Qt Creator:

    \list
        \o Retrieves data representing the call stack at the program's current
           position.
        \o Retrieves the contents of local variables.
        \o Examines \gui Watchers.
        \o Updates the \gui Registers, \gui Modules, and \gui Disassembler
           views if you are debugging the C++ language.
    \endlist

    You can use the \gui Debug mode views to examine the data in more detail.

    You can use the following keyboard shortcuts:

    \list

       \o To finish debugging, press \key{Shift+F5}.
       \o  To execute a line of code as a whole, press \key{F10}.
       \o  To step into a function or a subfunction, press \key{F11}.
       \o  To continue running the program, press \key{F5}.

    \endlist

    It is also possible to continue executing the program until the current
    function completes or jump to an arbitrary position in the current function.


    \section1 Setting Breakpoints

    A breakpoint represents a position or sets of positions in the code that,
    when executed, interrupts the program being debugged and passes the control
    to you. You can then examine the state of the interrupted program, or
    continue execution either line-by-line or continuously.

    Qt Creator shows breakpoints in the \gui{Breakpoints} view which is enabled
    by default. The \gui{Breakpoints} view is also accessible when the debugger
    and the program being debugged is not running.

    \image qtcreator-debug-breakpoints.png "Breakpoints view"

    Typically, breakpoints are associated with a source code file and line, or
    the start of a function -- both are allowed in Qt Creator.

    The interruption of a program by a breakpoint can be restricted with
    certain conditions.

    To set a breakpoint:

    \list
       \o At a particular line you want the program to stop, click the
          left margin or press \key F9 (\key F8 for Mac OS X).
       \o At a function that you want the program to interrupt, enter the
          function's name in \gui{Set Breakpoint at Function...} located in the
          context menu of the \gui{Breakpoints} view.
    \endlist

    \note You can remove a breakpoint:
    \list
        \o By clicking the breakpoint marker in the text editor.
        \o By selecting the breakpoint in the breakpoint view and pressing
           \key{Delete}.
        \o By selecting \gui{Delete Breakpoint} from the context
           menu in the \gui Breakpoints view.
    \endlist

    You can set and delete breakpoints before the program starts running or
    while it is running under the debugger's control. Breakpoints are saved
    together with a session.

    \section1 Viewing Call Stack Trace

    When the program being debugged is interrupted, Qt Creator displays the
    nested function calls leading to the current position as a call stack
    trace. This stack trace is built up from call stack frames, each
    representing a particular function. For each function, Qt Creator tries
    to retrieve the file name and line number of the corresponding source
    file. This data is shown in the \gui Stack view.

    \image qtcreator-debug-stack.png

    Since the call stack leading to the current position may originate or go
    through code for which no debug information is available, not all stack
    frames have corresponding source locations. Stack frames without
    corresponding source locations are grayed out in the \gui{Stack} view.

    If you click a frame with a known source location, the text editor
    jumps to the corresponding location and updates the \gui{Locals and Watchers}
    view, making it seem like the program was interrupted before entering the
    function.

    \section1 Locals and Watchers

    Whenever a program stops under the control of the debugger, it retrieves
    information about the topmost stack frame and displays it in the
    \gui{Locals and Watchers} view. The \gui{Locals and Watchers} view
    typically includes information about parameters of the function in that
    frame as well as the local variables.

    \image qtcreator-watcher.png "Locals and Watchers view"

    Compound variables of struct or class type are displayed as
    expandable in the view. Expand entries to show
    all members. Together with the display of value and type, you can
    examine and traverse the low-level layout of object data.


    \table

        \row
            \i  Gdb, and therefore Qt Creator's debugger works for optimized

                re-ordering of instructions or removal of some local variables,
                causing the \gui{Locals and Watchers} view to show unexpected
                data.

                Therefore, Qt Creator can not tell whether the contents of a
                local variable contains "real data", or "initial noise". If a
                QObject appears uninitialized, its value is reported as
                \gui {not in scope}. Not all uninitialized objects, however, can be
                recognized as such.
    \endtable


    The \gui{Locals and Watchers} view also provides access to the most
    powerful feature of the debugger: comprehensive display of data belonging
    to Qt's basic objects.

    To enable Qt's basic objects data display feature:
    \list
       \o  Select \gui Tools > \gui {Options...} > \gui Debugger >
           \gui{Debugging Helper} and check the \gui{Use Debugging Helper}
           checkbox.
       \o  The \gui{Locals and Watchers} view is reorganized to provide a
           high-level view of the objects.
    \endlist

    For example, in case of QObject, instead of displaying a pointer to some
    private data structure, you see a list of children, signals and slots.

    Similarly, instead of displaying many pointers and integers, Qt Creator's
    debugger displays the contents of a QHash or QMap in an orderly manner.
    Also, the debugger displays access data for QFileInfo and provides
    access to the "real" contents of QVariant.

    You can use the \gui{Locals and Watchers} view to change the contents of
    variables of simple data types, for example, \c int or \c float when the
    program is interrupted. To do so, click the \gui Value column, modify
    the value with the inplace editor, and press \key Enter (or \key Return).

    You can enable tooltips in the main editor displaying this information.
    For more information, see \l{Showing Tooltips in Debug Mode}.

    \note The set of watched items is saved in your session.

    \section1 Debugging the C++ Language

    The following sections describe additional debugging functions that apply
    only to debugging C++.

    \section2 Starting the Debugger from the Command Line

    You can use the Qt Creator debugger interface from the command line. To
    attach it to a running process, specify the process ID as a parameter for
    the \c {-debug} option. To examine a core file, specify the file name.
    Qt Creator executes all the necessary steps, such as searching for
    the binary that belongs to a core file.

    For example:

    \list

        \o \c {C:\qtcreator-2.1\bin>qtcreator -debug 2000}

        \o \c {C:\qtcreator-2.1\bin>qtcreator -debug core.2000}

    \endlist

    For more information, see \l{Using Command Line Options}.

    \section2 Stepping into Frameworks in Mac OS

    In Mac OS X, external libraries are usually built into so-called Frameworks,
    which may contain both release and debug versions of the library. When you run
    applications on the Mac OS desktop, the release version of Frameworks is used
    by default. To step into Frameworks, select the \gui {Use debug versions of
    Frameworks} option in the project run settings for \gui Desktop and
    \gui {Qt Simulator} targets.

    \section2 Viewing Threads

    If a multi-threaded program is interrupted, the \gui Thread view or the
    combobox named \gui Thread in the debugger's status bar can be used to
    switch from one thread to another. The \gui Stack view adjusts itself
    accordingly.

    \section2 Viewing Modules and Source Files

    The \gui{Modules} view and \gui{Source Files} views display information
    that the debugger plugin has about modules and source files included in
    the project. The \gui{Modules} view lists the modules in the project and
    symbols within the modules. In addition, it indicates where the module
    was loaded.

    The \gui{Source Files} view lists all the source files included in the project.
    If you cannot step into an instruction, you can check whether the source file is
    actually part of the project, or whether it was compiled
    elsewhere. The view shows the path to each file in the file system.

    By default, the \gui{Modules} view and \gui{Source Files} view are hidden.


    \section2 Viewing Disassembled Code and Register State

    The \gui{Disassembler} view displays disassembled code for the current
    function. The \gui{Registers} view displays the current state of the CPU's
    registers.

    The \gui{Disassembler} view and the \gui{Registers} view are both useful
    for low-level commands for checking single instructions, such as \gui{Step Into}
    and \gui{Step Over}. By default, both \gui{Disassembler} and
    \gui{Registers} view are hidden.

    \title Debugging the Example Application

    This section uses the \l{Creating a Qt C++ Application}{TextFinder} example to
    illustrate how to debug Qt C++ applications in the \gui Debug mode.

    TextFinder
    reads a text file into
    QString and then displays it with QTextEdit.
    To look at the example QString, \c{line}, and see the
    stored data, place a breakpoint and view the QString object
    data, as follows:

    \list 1
        \o Click in between the line number and the window border on the line
        where we invoke \l{http://doc.qt.nokia.com/4.7/qtextedit.html#plainText-prop}{setPlainText()}
        to set a breakpoint.

        \image qtcreator-setting-breakpoint1.png

        \o Select \gui{Debug > Start Debugging > Start Debugging} or press \key{F5}.


        \o To view the breakpoint, click the \gui{Breakpoints} tab.

        \image qtcreator-setting-breakpoint2.png

        \o To remove a breakpoint, right-click it and select \gui{Delete Breakpoint}.


        \o To view the contents of \c{line}, go to the \gui{Locals and
    Watchers} view.

        \image qtcreator-watcher.png

    \endlist

    Modify the \c{on_findButton_clicked()} function to move back to
    the start of the document and continue searching once the cursor hits the
    end of the document. Add the following code snippet:

    \code
    void TextFinder::on_findButton_clicked()
    {
        QString searchString = ui->lineEdit->text();

        QTextDocument *document = ui->textEdit->document();
        QTextCursor cursor = ui->textEdit->textCursor();
        cursor = document->find(searchString, cursor,
            QTextDocument::FindWholeWords);
        ui->textEdit->setTextCursor(cursor);

        bool found = cursor.isNull();

        if (!found && previouslyFound) {
            int ret = QMessageBox::question(this, tr("End of Document"),
            tr("I have reached the end of the document. Would you like "
            "me to start searching from the beginning of the document?"),
            QMessageBox::Yes | QMessageBox::No, QMessageBox::Yes);

            if (ret == QMessageBox::Yes) {
                cursor = document->find(searchString,
                    QTextDocument::FindWholeWords);
                ui->textEdit->setTextCursor(cursor);
            } else
                return;
        }
        previouslyFound = found;
    }
    \endcode

    If you compile and run the above code, however, the application does not
    work correctly due to a logic error. To locate this logic error, step
    through the code using the following buttons:

    \title Using Debugging Helpers

    Qt Creator is able to show complex data types in a customized,
    user-extensible manner. For this purpose, it takes advantage of
    two technologies, collectively referred to as \e{Debugging Helpers}.

    Using the debugging helpers is not \e essential for debugging
    with Qt Creator, but they enhance the user's ability to quickly
    examine complex data significantly.

    \section1 Debugging Helpers Based on C++

    This is the first and original approach to display complex data
    types. While it has been superseded on most platforms by the more
    robust and more flexible second approch using Python scripting,
    it is the only feasible one on Windows/MSVC, Mac OS, and
    old Linux distributions. Moreover, this approach will automatically
    be chosen as fallback in case the Python based approach fails.

    During debugging with the C++ based debugging helpers,
    Qt Creator dynamically loads a helper library in form of a DLL or a
    shared object into the debugged process.
    The \QSDK package already contains a prebuilt debugging helper
    library. To create your own debugging helper library, select \gui{Tools} >
    \gui{Options...} > \gui{Qt4} > \gui{Qt Versions}. As the internal data
    structures of Qt can change between versions, the debugging helper
    library is built for each Qt version.


    \section1 Debugging Helpers Based on Python

    On platforms featuring a Python-enabled version of the gdb debugger,
    the data extraction is done by a Python script. This is more robust
    as the script execution is separated from the debugged process. It
    is also easier to extend as the script is less dependent on the
    actual Qt version and does not need compilation.

    To extend the shipped Python based debugging helpers for custom types,
    define one Python function per user defined type in the
    gdb startup file. By default, the following startup file is used:
    \c{~/.gdbinit}. To use another file, select \gui {Tools > Options... > Gdb}
    and specify a filename in the \gui {Gdb startup script} field.

    The function name has to be qdump__NS__Foo, where NS::Foo is the class
    or class template to be examined. Nested namespaces are possible.

    The debugger plugin calls this function whenever you want to
    display an object of this type. The function is passed the following
    parameters:
    \list
       \o  \c d of type \c Dumper
       \o  \c item of type \c Item
    \endlist

    The function has to feed the Dumper object with certain information
    which is used to build up the object and its children's display in the
    \gui{Locals and Watchers} view.


    Example:

    \code
    def qdump__QVector(d, item):
        d_ptr = item.value["d"]
        p_ptr = item.value["p"]
        alloc = d_ptr["alloc"]
        size = d_ptr["size"]

        check(0 <= size and size <= alloc and alloc <= 1000 * 1000 * 1000)
        check(d_ptr["ref"]["_q_value"] > 0)

        innerType = item.value.type.template_argument(0)
        d.putItemCount(size)
        d.putNumChild(size)
        if d.isExpanded(item):
            p = gdb.Value(p_ptr["array"]).cast(innerType.pointer())
            with Children(d, [size, 2000], innerType)
                for i in d.childRange():
                    d.putSubItem(Item(p.dereference(), item.iname, i))
                    p += 1
    \endcode

    \section2 Item Class

    The Item Python class is a thin wrapper around values corresponding to one
    line in the \gui{Locals and Watchers} view. The Item members are as follows :

    \list

    \o \gui{__init__(self, value, parentiname, iname, name = None)} - A
       constructor. The object's internal name is created by concatenating
       \c parentiname and \c iname. If \c None is passed as \c name, a
       serial number is used.

    \o \gui{value} - An object of type gdb.Value representing the value to
        be displayed.

    \o \gui{iname} - The internal name of the object, constituting a dot-separated
    list of identifiers, corresponding to the position of the object's
    representation in the view.

    \o \gui{name} - An optional name. If given, is used in the
    \gui{name} column of the view. If not, a simple number in brackets
    is used instead.

    \endlist


    \section2 Dumper Class

    For each line in the \gui{Locals and Watchers} view, a string like the
    following needs to be created and channeled to the debugger plugin.
    \code
    "{iname='some internal name',
      addr='object address in memory',
      name='contents of the name column',
      value='contents of the value column',
      type='contents of the type column',
      numchild='number of children',        // zero/nonzero is sufficient
      childtype='default type of children', // optional
      childnumchild='default number of grandchildren', // optional
      children=[              // only needed if item is expanded in view
         {iname='internal name of first child',
          ... },
         {iname='internal name of second child',
          ... },
         ...
      ]}"
    \endcode

    While in theory, you can build up the entire string above manually, it is
    easier to employ the Dumper Python class for that purpose. The Dumper
    Python class contains a complete framework to take care of the \c iname and
    \c addr fields, to handle children of simple types, references, pointers,
    enums, known and unknown structs as well as some convenience methods to
    handle common situations.

    The Dumper members are the following:

    \list

    \o \gui{__init__(self)} - Initializes the output to an empty string and
        empties the child stack.

    \o \gui{put(self, value)} - Low level method to directly append to the
        output string.

    \o \gui{putCommaIfNeeded(self)} - Appends a comma if the current output
        ends in '}', '"' or ']' .

    \o \gui{putField(self, name, value)} - Appends a comma if needed, and a
         name='value' field.

    \o \gui{beginItem(self, name)} - Starts writing a field by writing \c {name='}.

    \o \gui{endItem(self)} - Ends writing a field by writing \c {'}.

    \o \gui{endChildren(self)} - Ends writing a list of children.

    \o \gui{childRange(self)} - Returns the range of children specified in
        the current \c Children scope.

    \o \gui{putItemCount(self, count)} - Appends a field  \c {value='<%d items'}
        to the output.

    \o \gui{putEllipsis(self)} - Appends fields
        \c {'{name="<incomplete>",value="",type="",numchild="0"}'}. This is
        automatically done by \c endChildren if the number of children to
        print is smaller than the number of actual children.

    \o \gui{putName(self, name)} - Appends a \c {name='...'} field.

    \o \gui{putType(self, type)} - Appends a field \c {type='...'} unless the
        \a type coincides with the parent's default child type.

    \o \gui{putNumChild(self, numchild)} - Appends a field \c {numchild='...'}
        unless the \c numchild coincides with the parent's default child numchild
        value.

    \o \gui{putValue(self, value, encoding = None)} - Append a file \c {value='...'},
        optionally followed by a field \c {valueencoding='...'}. The \c value
        needs to be convertible to a string entirely consisting of
        alphanumerical values. The \c encoding parameter can be used to
        specify the encoding in case the real value had to be encoded in some
        way to meet the alphanumerical-only requirement.
        Currently the following encodings are supported:

        \list
            \o 0: unencoded 8 bit data, interpreted as Latin1.

            \o 1: base64 encoded 8 bit data, used for QByteArray,
                double quotes are added.

            \o 2: base64 encoded 16 bit data, used for QString,
                double quotes are added.

            \o 3: base64 encoded 32 bit data,
                double quotes are added.

            \o 4: base64 encoded 16 bit data, without quotes (see 2)

            \o 5: base64 encoded 8 bit data, without quotes (see 1)

            \o 6: %02x encoded 8 bit data (as with \c QByteArray::toHex),
                double quotes are added.

            \o 7: %04x encoded 16 bit data (as with \c QByteArray::toHex),
                double quotes are added.
        \endlist

    \o \gui{putStringValue(self, value)} - Encodes a QString and calls
        \c putValue with the correct \c encoding setting.

    \o \gui{putByteArrayValue(self, value)} - Encodes a QByteArray and calls
        \c putValue with the correct \c encoding setting.

    \o \gui{isExpanded(self, item)} - Checks whether the item with the
        internal name \c item.iname is expanded in the view.

    \o \gui{isExpandedIName(self, iname)} - Checks whether the item with the
        internal name \c iname is expanded in the view.

        \o \gui{putIntItem(self, name, value)} - Equivalent to:
        \code
        self.beginHash()
        self.putName(name)
        self.putValue(value)
        self.putType("int")
        self.putNumChild(0)
        self.endHash()
        \endcode

        \o \gui{putBoolItem(self, name, value)} - Equivalent to:
        \code
        self.beginHash()
        self.putName(name)
        self.putValue(value)
        self.putType("bool")
        self.putNumChild(0)
        self.endHash()
        \endcode

    \o \gui{pushOutput(self)} - Moves the output string to a safe location
        from with it is sent to the debugger plugin even if further operations
        raise an exception.

    \o \gui{putCallItem(self, name, item, func)} -
        Uses gdb to call the function \c func on the value specified by
        \a {item.value} and output the resulting item. This function is
        not available when debugging core dumps and it is not available
        on the Symbian platform due to restrictions imposed by AppTRK.

    \o \gui{putItem(self, item)} - The "master function", handling
        basic types, references, pointers and enums directly, iterates
        over base classes and class members of compound types and calls
        \c qdump__* functions whenever appropriate.

    \o \gui{putSubItem(self, item)} - Equivalent to:
        \code
        with SubItem(self):
            self.putItem(item)
        \endcode
        Exceptions raised by nested function calls are caught and all
        output produced by \c putItem is replaced by the output of:
        \code
            ...
        except RuntimeError:
            d.put('value="<invalid>",type="<unknown>",numchild="0",')
        \endcode

    \endlist


    \section2 Children and SubItem Class

    The attempt to create child items might lead to errors if data is
    uninitialized or corrupted. To gracefully recover in such situations,
    use \c Children and \c SubItem \e{Context Managers} to create the nested items.

    The \c Children constructor \gui{__init__(self, dumper, numChild = 1,
    childType = None, childNumChild = None)} uses one mandatory argument and three
    optional arguments.  The mandatory argument refers to the current \c Dumper
    object.  The optional arguments can be used to specify the number \c numChild
    of children, with type \c childType_ and \c childNumChild_ grandchildren each.
    If \c numChild_ is a list of two integers, the first one specifies the actual
    number of children and the second the maximum number of children to print.

    Similarly, using the \c SubItem class helps to protect individual items.

    Example:
    \code
    d.putNumChild(2)
    if d.isExpanded(item):
        with Children(d):
            with SubItem(d):
                d.putName("key")
                d.putItem(Item(key, item.iname, "key"))
            with SubItem(d):
                d.putName("value")
                d.putItem(Item(value, item.iname, "value"))
    \endcode

    \section1 Debugging Helpers for QML

    The debugging helpers for QML provide you with code completion for custom modules
    (\c qmldump) and debugging Qt Quick UI projects (\c qmlobserver).

    You have to build the QML Observer once for each Qt version that you want to debug
    with. Select \gui{Tools > Options... > Qt4 > Qt Versions}.

    \note QML Observer requires Qt 4.7.1 or later.

    \title Setting Up a CMake Project

    CMake is an alternative to qmake for automating the generation of makefiles.
    It controls the software compilation process by using simple configuration
    files, called CMakeLists.txt files. CMake generates native makefiles and
    workspaces that you can use in the compiler environment of your choice.

    Since Qt Creator 1.1, CMake configuration files are supported.
    Qt Creator 1.3 supports the Microsoft Toolchain if the CMake version
    is at least 2.8.

    \section1 Setting the Path for CMake

    You can set the path for the \c CMake executable in \gui{Tools} >
    \gui{Options... > Projects > CMake}.

    \image qtcreator-cmakeexecutable.png

    \note Before you open a \c CMake project it is necessary to modify the
    \c{PATH} environment variable to include the bin folders of \c mingw and
    Qt Creator in the SDK.

    For instance, if you have the Qt Creator SDK installed in your C drive,
    use the following command to set the environment variables in
    the command line prompt:
    \code
    set PATH=C:\qtsdk\mingw\bin;C:\qtsdk\qt\bin;
    \endcode
    Then start Qt Creator by typing:
    \code
    C:\qtsdk\bin\qtcreator.exe
    \endcode

    \section1 Opening CMake Projects

    To open a \c CMake project:
    \list 1
        \o  Select \gui{File} > \gui{Open File or Project...}.
        \o  Select the \c{CMakeLists.txt} file from your \c CMake project.
    \endlist

    A wizard guides you through the rest of the process.

    \note If the \c CMake project does not have an in-place build, Qt Creator
    lets you specify the directory in which the project is built
   (\l{glossary-shadow-build}{shadow build}).

    \image qtcreator-cmake-import-wizard1.png

    The screenshot below shows how you can specify command line arguments to
    \c CMake for your project.

    \image qtcreator-cmake-import-wizard2.png

    Normally, there is no need to pass any command line arguments for projects
    that are already built, as \c CMake caches that information.


    \section1 Building CMake Projects

    Qt Creator builds \c CMake projects by running \c make, \c mingw32-make, or
    \c nmake depending on your platform. The build errors and warnings are
    parsed and displayed in the \gui{Build Issues} output pane.

    By default, Qt Creator builds the \bold{all} target. You can specify which
    targets to build in \gui{Project} mode, under \gui{Build Settings}.

    \image qtcreator-cmake-build-settings.png

    Qt Creator supports multiple build configurations. The build
    directory can also be modified after the initial import.

    \section1 Running CMake Projects
    Qt Creator automatically adds \gui{Run Configurations} for all targets
    specified in the \c CMake project file.

    Known issues for the current version can be found
    \l{Known Issues}{here}.


    \section1 Adding External Libraries to CMake Projects

    Through external libraries Qt Creator can support code completion and
    syntax highlighting as if they were part of the current project or the Qt
    library.

    Qt Creator detects the external libraries using the \c FIND_PACKAGE()
    macro. Some libraries come with the CMake installation. You can find those
    in the \bold{Modules} directory of your CMake installation.

    \note If you provide your own libraries, you also need to provide your own
    \c FindFoo.cmake file. For more information, see
    \l{http://vtk.org/Wiki/CMake_FAQ#Writing_FindXXX.cmake_files}{CMake FAQ}.

    Syntax completion and highlighting work once your project successfully
    builds and links against the external library.

    \title Debugging Qt Quick Projects

    \note You need Qt 4.7.1 or later to debug Qt Quick projects.

    \section1 Setting Up QML Debugging

    The process of setting up debugging for Qt Quick projects depends on the type of
    the project: Qt Quick UI or Qt Quick Application.

    To debug Qt Quick UI projects, you must compile the debugging helpers. For more
    information, see \l{Debugging Helpers for QML}.

    To debug Qt Quick Applications, you must modify the project file to comment in the
    following line:

    \c {DEFINES += QMLJSDEBUGGER}.

    Then you must rebuild the project.

    To enable QML debugging for  both types of projects, select \gui Projects, and
    then select the \gui QML check box in the run settings.

    \section1 Starting QML Debugging

    To start the application, choose \gui {Debug > Start Debugging
    > Start Debugging} or press \key F5. Once the application starts running, it behaves
    and performs as usual. You can then perform the following tasks:

    \list

        \o Debug JavaScript functions

        \o Preview QML changes at runtime

        \o Inspect QML at runtime

    \endlist

    \section1 Debugging JavaScript Functions

    You can use the Qt Creator \gui Debug mode to inspect the state of your
    application while debugging. You can interact with the debugger in several
    ways, as described in the following sections:

    \list

        \o \l{Setting Breakpoints}

        \o \l{Viewing Call Stack Trace}

        \o \l{Locals and Watchers}

    \endlist

    \section1 Executing JavaScript Expressions

    When the application is interrupted by a breakpoint, you can use the \gui {QML
    Script Console} to execute JavaScript expressions in the current context. To
    open it, choose \gui {Window > View > QML Script Console}.

    \image qml-script-console.png "QML Script Console view"

    You can type JavaScript expressions and use them to get information about the
    state or your application. For example, property values.

    You can see the current value of a property by hovering over it in the code editor.

    \section1 Previewing QML Changes at Runtime

    If you change property values or add properties in the code editor, the changes
    are updated in the running application when you save them. If live preview is not supported
    for an element, a message appears. Click \gui Reload to preview the changes.

    Reloading is enabled by default. To disable it, click
    \inlineimage qml-observer-bar-reload.png "Apply Changes on Save button"
    in the \gui {QML Observer} view.

    \section1 Inspecting QML at Runtime

    While the application is running, you can use the \gui {QML Observer} view to
    explore the object structure, debug animations, and inspect colors.
    To open the \gui {QML Observer} view, choose \gui {Window > View > QML Observer}.

    \image qml-observer-view.png "QML Observer view"

    When you debug complex applications, you can use the observe
    mode to jump to the position in code where an element is defined. To switch to
    the observe mode, click
    \inlineimage qml-observer-bar-observe.png
    in the \gui {QML Observer} view.

    Click elements in the running application to jump to their definitions in the code.
    Double-click elements to browse the element hierarchy. The hierarchy is displayed
    as bread crumbs in the \gui {QML Observer} view.

    You can also right-click an element in the running application to view the element
    hierarchy as a context menu. Select an element to jump to its definition in code.

    To zoom in and out of the application, click the \gui Zoom button.

    To inspect colors, click the \gui {Color Picker} button. You can also the click
    \inlineimage qml-observer-bar-copy-color.png "Copy Color button"
    to copy the color definition to the clipboard.

    \section1 Debugging Animations

    \image qml-observer.png

    To play and pause animations in the running application, click the \gui {Play/Pause Animations}
    button in the \gui {QML Observer} view or \gui {Debugging > Animations > Pause} or press
    \key {Ctrl+.}.

    To step through an animation, select \gui {Debugging > Animations > Pause & Step}
    or press \key {Ctrl+,}.

    To set step duration in milliseconds, select \gui {Debugging > Animations > Set Step}.
    To change the speed at which animations are played, select a value in \gui {Debugging
    > Animations}.

    \title Setting Up a Generic Project

    Qt Creator supports generic projects, so you can import existing projects
    that do not use qmake or CMake and Qt Creator ignores your build system.

    Generic project support allows you to use Qt Creator as a code editor. You
    can change the way your project is built by modifying the \c make command
    in the \gui{Projects} mode under \gui{Build Settings}.

    When you import a project, Qt Creator creates the following files that
    allow you to specify which files belong to your project and which include
    directories or defines you want to pass to your compile:
    \tt{.files}, \tt{.includes}, and \tt{.config}.


    \section1 Importing a Generic Project

    To import an existing generic project:
    \list 1
        \o Select \gui File > \gui{New File or Project...} >
           \gui{Other Project} > \gui{Import Existing Project}.
        \o In \gui{Import Existing Project}, enter the project name
           and select the location of the project file you want to import.

           Qt Creator automatically generates the following files in the
           project directory:
           \list
               \o \l{Specifying Files}{.files}
               \o \l{Specifying Include Paths}{.includes}
               \o \l{Specifying Defines}{.config}
               \o .creator
           \endlist
    \endlist

    When the project is successfully imported, Qt Creator creates the project
    tree in the sidebar.

    After importing a generic project into Qt Creator, open it by selecting the
    \tt{.creator} file.


    \section1 Working with Generic Project Files

    For a generic project, you have to manually specify which files belong to
    your project and which include directories or defines you want to pass to
    your compiler.


    \section1 Specifying Files

    The list of files for a generic project is specified in the \tt{.files}
    file. When you first create a generic project, Qt Creator adds any
    files it recognizes to your project.

    To add or remove files, edit the \tt{.files} file in Qt Creator.
    Qt Creator recreates your project tree when you save the \tt{.files} file.
    Alternatively, you can add and remove files using the context menu in the
    project tree.

    If you frequently need to update the \tt{.files} file, you can do so
    efficiently by using a script that updates the file for you. If the file
    is modified externally, you have to restart Qt Creator for the changes to
    take effect.

    To update the \tt{.files} on the \gui Git repository use the following
    script:
    \code
    git ls-files *.cpp *.h > MyProject.files
    \endcode

    \section1 Specifying Include Paths

    The include paths are specified in the \tt{.includes} file, one include
    path per line. The paths can be either absolute or relative to the
    \tt{.includes} file.

    \section1 Specifying Defines

    The defines are specified in the \tt{.config} file. The \tt{.config} file is
    a regular C++ file, prepended to all your source files when they are parsed.
    Only use the \tt{.config} file to add lines as in the example below:

    \code
    #define NAME value
    \endcode


    \section1 Creating a Run Configuration

    Qt Creator cannot automatically determine which executable to run.

    In the \gui{Projects} mode under \gui{Run Settings}, define the executable
    file to run:
    \list 1
        \o Click \gui Add and select \gui{Custom Executable}.
        \o Define the configuration name, the location of the executable, any
           additional arguments and the working directory.
    \endlist

    \title Creating Qt Quick Projects

        \image qmldesigner-new-project.png "New File or Project dialog"

    When you create a new Qt Quick project from scratch, you have the following options:

    \list

        \o \gui {Qt Quick UI} creates a Qt Quick UI project with a single QML file that
        contains the main view. You can review Qt Quick UI projects in the QML Viewer and you
        need not build them. You do not need to have the development environment installed on your
        computer to create and run this type of projects.

        \o \gui {Qt Quick Application} creates a Qt Quick application project that can
        contain both QML and C++ code. The project includes a QDeclarativeView. You can build
        the application and deploy it on desktop and mobile target platforms. For example, you
        can create signed Symbian Installation System (SIS) packages for this type of projects.

        \o \gui {Custom QML Extension Plugin} creates a C++ plugin that makes it possible
        to offer extensions that can be loaded dynamically into applications by using the
        QDeclarativeEngine class.

    \endlist

    If you have existing QML applications that you want to run in Qt Creator or deploy
    to mobile devices, use the \gui {Qt Quick Application} wizard to convert them
    to Qt Quick applications.

    \section1 Creating Qt Quick UI Projects

    \list 1

        \o Select \gui {File > New File or Project > Qt Quick Project > Qt Quick UI
        > Choose...}.

        The \gui{Introduction and Project Location} dialog opens.

        \image qmldesigner-new-project-location.png "Introduction and Project Location dialog"

        \o In the \gui Name field, give a name to the project.

        Do not use spaces and special characters in the project name and path.

        \o In the \gui {Create in} field, enter the path for the project files. For example,
        \c {C:\Qt\examples}. To select the path from a directory tree, click \gui Browse.

        \o Click \gui{Next}.

        \image qmldesigner-new-ui-project-summary.png "Project Management dialog"

        \o Review the project settings, and click \gui{Finish} to create the project.


    \endlist

    Qt Creator creates the following files:

    \list

    \o .qmlproject project file defines that all QML, JavaScript, and image
    files in the project folder belong to the project. Therefore, you do not
    need to individually list all the files in the project.

    \o .qml file defines an element, such as a component, screen, or the whole
    application UI.

    \endlist

    The \c import statement in the beginning of the .qml file specifies the
    \l {http://doc.qt.nokia.com/4.7/qdeclarativemodules.html} {Qt modules}
    to import. Each Qt module contains a set of default elements.
    Specify a version to get the features you want.

    To use JavaScript and image files in the application, copy them to the
    project folder.

    \section1 Creating Qt Quick Applications

    \list 1

        \o Select \gui {File > New File or Project > Qt Quick Project > Qt Quick Application
        > Choose...}.

        The \gui{Introduction and Project Location} dialog opens.

        \image qmldesigner-new-project-location.png "Introduction and Project Location dialog"

        \o In the \gui Name field, give a name to the project.

        Do not use spaces and special characters in the project name and path.

        \o In the \gui {Create in} field, enter the path for the project files. For example,
        \c {C:\Qt\examples}. To select the path from a directory tree, click \gui Browse.

        \o Click \gui{Next}.

        The \gui {Qt Versions} dialog opens.

        \o Select the Qt versions to use as build targets for your project,
        and then click \gui{Next}.

        \note Qt Quick is supported since Qt 4.7, and therefore, only Qt 4.7 and later
        versions are displayed. Further, if you have only one supported Qt version installed,
        this dialog is skipped.

        The \gui{Application Options} dialog opens.

        \image qtcreator-mobile-project-app-options.png "Application Options dialog"

        \o In the \gui {Orientation behavior} field, determine how the application
        behaves when the orientation of the device display rotates between portrait
        and landscape.

        \o In the \gui {Application icon} field, select an application icon.

        \o In the \gui {Target UID3} field, specify the \l{Application UID}.

        \note Qt Creator generates a UID for testing the application on a device.
        You need to change the UID when you deliver the application for public
        use.

        \o If the application needs network connectivity, select the
        \gui {Enable network access} check box, and then click \gui{Next}.

        The \gui {QML Sources} dialog opens.

        and then click \gui{Next}.

        The \gui {Project Management} dialog opens.

        \image qmldesigner-new-project-summary.png "Project Management" dialog

        \o In the \gui {Add to project} field, you can add this project to another
        project as a subproject.

        \o In the \gui {Add to version control} field, you can add the project to
        a version control system.

        \o Click \gui Finish to create the project.

    \endlist

    Qt Creator creates the necessary boilerplate files. Some of the files are
    specific to the Symbian or Maemo platform.

    \section1 Importing QML Applications

    If you have existing QML applications that you want to run in Qt Creator or deploy
    to mobile devices, use the \gui {Qt Quick Application} wizard and select the main
    .qml file in your project. All the other files in the project are automatically added
    to the application project.

    For example, you can open and run the
    \l {http://doc.qt.nokia.com/4.7/qdeclarativeexamples.html} {QML examples and demos}
    to learn how to use various aspects of QML. To run the examples in the QML Viewer
    on the desktop, open them in the \gui Welcome mode. To view the examples on
    mobile devices, use the \gui {Qt Quick Application} wizard to convert them into
    Qt Quick Applications.

    To import QML applications:

    \list 1

        \o Select \gui {File > New File or Project > Qt Quick Project > Qt Quick Application
        > Choose...}.

        \o Name the project and set its path, and then click \gui Next.

        \o Select the Qt versions to use as build targets for your project, and click
        \gui{Next}.

        \o Specify options for deploying the application to mobile device targets, and
        click \gui{Next}.

        \o In the \gui {QML Sources} dialog, select the \gui {Import an existing .qml file}
        option and specify the main .qml file of the project you want to import.

        \image qmldesigner-import-project.png "QML Sources" dialog

        \o Click \gui Next.

        \o Review the project settings, and click \gui{Finish} to create the project.

    \title Creating Components

    A QML component provides a way of defining a new type that you can re-use in other QML
    files. A component is like a black box; it interacts with the outside world
    through properties, signals, and slots, and is generally defined in its own QML file.
    You can import components to screens and applications.

    You can use the following QML elements to create components:

    \list

        \o \l{http://doc.qt.nokia.com/4.7/qml-borderimage.html}{Border Image}
        uses an image as a border or background.
        \o \l{http://doc.qt.nokia.com/4.7/qml-image.html}{Image}
        adds a bitmap to the scene. You can stretch and tile images.
        \o \l{http://doc.qt.nokia.com/4.7/qml-item.html}{Item}
        is the most basic of all visual items in QML. Even though it has no visual appearance,
        it defines all the properties that are common across visual items, such as the x and
        y position, width and height, anchoring, and key handling.
        \o \l{http://doc.qt.nokia.com/4.7/qml-rectangle.html}{Rectangle}
        adds a rectangle that is painted with a solid fill color and an optional border.
        You can also use the radius property to create rounded rectangles.
        \o \l{http://doc.qt.nokia.com/4.7/qml-text.html}{Text}
        adds formatted read-only text.
        \o \l{http://doc.qt.nokia.com/4.7/qml-textedit.html}{Text Edit}
        adds a single line of editable formatted text that can be validated.
        \o \l{http://doc.qt.nokia.com/4.7/qml-textinput.html}{Text Input}
        adds a single line of editable plain text that can be validated.

    \title Creating Buttons

    To create a button component:

    \list 1

        \o Select \gui {File > New File or Project > QML > QML File > Choose...} to
         create a QML file called Button.qml (for example).

        \note Components are listed in the \gui Library pane only if the filename
        begins with a capital letter.

        \o Click \gui {Design} to edit the file in the visual editor.

        \o In the \gui Navigator pane, click \gui Rectangle to set properties
        for it.

        \o In the \gui Properties pane, modify the appearance of the button.

        \list a

            \o In the \gui Size field, set the width (\gui W) and height (\gui H)
            of the button.

            \o In the \gui Color field, select the button color.

            \o In the \gui Radius field, use the slider to set the radius of the
            rectangle and produce rounded corners for the button.

        \endlist

        \o Drag and drop a \gui {Text} item on top of the \gui Rectangle. This
        creates a nested element where \gui Rectangle is the parent element of
        \gui Text. Elements are positioned relative to their parents.

        \o In the \gui Properties pane, edit the properties of the \gui Text item.

        \list a

            \o In the \gui Text field, type \bold Button.

            You can select the text color, font, size, and style in the \gui Font
            section.

            \o In the \gui Alignment field, select the center buttons to align
            the text to the center of the button.

            \o Click \gui {Layout}, and then click the
            \inlineimage qmldesigner-anchor-fill-screen.png
            button to anchor the text to the whole button area.

        \endlist

        \o Press \key {Ctrl+S} to save the button.

        \image qmldesigner-button.png "Button component"

    \endlist

    \note To view the button, you must add it to a Qt Quick Application or Qt Quick UI
    project.

    To create a graphical button that scales beautifully without using vector graphics,
    use the \l{http://doc.qt.nokia.com/4.7/qml-borderimage.html}{Border Image}
    element. For more information, see \l{Creating Scalable Buttons and Borders}.

    \title Creating Scalable Buttons and Borders

    You can use the \l{http://doc.qt.nokia.com/4.7/qml-borderimage.html}{Border Image}
    element to display an image, such as a PNG file, as a border and a background.

    Use two Border Image elements and suitable graphics to make it look like the button
    is pushed down when it is clicked. One of the Border Image elements is visible by default.
    You can specify that it is hidden and the other one becomes visible when the mouse
    is clicked.

    Add a MouseArea that covers the whole area and emits the clicked signal (\c {parent.clicked()})
    when it detects a mouse click.

    You can add text to the button and set it up as a property. The text can then be initialized
    from the outside, making the button a reusable UI component. The font size is also available
    in case the default size is too big. You can scale down the button text and use smooth text
    rendering for some extra quality.

    \image qmldesigner-borderimage.png "Graphical button"

    To create a graphical button:

    \list 1

        \o Select \gui {File > New File or Project > QML > QML File > Choose...} to create
        a QML file called Button.qml (for example).

        \o Double-click the file to open it in the code editor.

        \o Replace the \gui Rectangle with an \gui Item, as illustrated by the
        following code snippet:

        \code

        Item {

        }

        \endcode

        \o Specify properties and set expressions for the \gui Item, as
        illustrated by the following code snippet:

    \title Creating Screens

    You can use predefined QML elements and your own components to create screens.
    Typically, the main qml file in a Qt Quick project specifies the main window of an
    application.

    The QML files in the project folder are displayed in \gui {QML Components} in the
    \gui Library pane.

    \section1 Adding Components to Screens

    \list 1

        \o Drag and drop components from the \gui Library pane to the editor.

        \o Select components in the \gui Navigator pane to edit their properties
        in the \gui Properties pane.

        For example, you can anchor components to a position on the screen.

    \endlist

    \section1 Organizing Items on Screens

    You can create the following types of views to organize items provided by
    \l{http://doc.qt.nokia.com/4.7/qdeclarativemodels.html}{data models}:

    \list

        \o \l{http://doc.qt.nokia.com/4.7/qml-gridview.html}{Grid View}
        \o \l{http://doc.qt.nokia.com/4.7/qml-listview.html}{List View}
        \o \l{http://doc.qt.nokia.com/4.7/qml-pathview.html}{Path View}

    \endlist

    In the code editor, write the code to use the data models.

    \section1 Using States

    Use states and transitions
    to navigate between screens.

    QML states typically describe user interface configurations, such as the UI elements,
    their properties and behavior and the available actions. For example, you can use
    states to create two screens.

    To add states, click the empty slot in the \gui States pane. Then modify the new state
    in the visual editor.

    \image qmldesigner-states.png "States pane"

    The properties that you change in a state are highlighted with blue color.
    In the code editor, you can see the changes recorded as changes to the base state.

    \title Animating Screens

    To make movement between states smooth, you can specify transitions.
    You can use different types of animated transitions. For example, you can animate changes
    to property values and colors. You can use rotation animation to control the direction of
    rotation. For more information, see
    \l{http://doc.qt.nokia.com/4.7/qdeclarativeanimation.html}{QML Animation}.

    You can use the \c ParallelAnimation element to start several animations at the same time.
    Or use the \c SequentialAnimation element to run them one after another.

    You can use the code editor to specify transitions. For more information, see
    \l{http://doc.qt.nokia.com/4.7/qml-transition.html}{QML Transition Element}.

    \title Using Qt Quick Toolbars

    When you edit QML code in the code editor, you specify the properties
    of QML components. For some properties, such as colors and font names,
    this is not a trivial task. For example, few people can visualize the
    color #18793f.

    To easily edit these properties, you can use the Qt Quick Toolbars.
    When you select a component in the code and a toolbar is available,
     a light bulb icon appears:
    \inlineimage qml-toolbar-indicator.png
    . Select the icon to open the toolbar.

    To open toolbars immediately when you select a component, select
    \gui{Tools > Options... > Qt Quick > Qt Quick Toolbar > Always show Quick
    Toolbar}.

    Drag the toolbar to pin it to another location. Select
    \inlineimage qml-toolbar-pin.png
    to unpin the toolbar and move it to its default location. To pin toolbars
    by default, select \gui{Tools > Options... > Qt Quick > Qt Quick Toolbar
    > Pin Quick Toolbar}.

    \section1 Previewing Images

    The Qt Quick Toolbar for images allows you to edit the properties of
    \l{http://doc.qt.nokia.com/latest/qml-borderimage.html}{Border Image}
    and \l{http://doc.qt.nokia.com/latest/qml-image.html}{Image} components.
    You can scale and tile the images, replace them with other images,
    preview them, and change the image margins.

    \image qml-toolbar-image.png "Qt Quick Toolbar for images"

    To preview an image, double-click it on the toolbar. In the preview
    dialog, you can zoom the image. Drag the image margins to change them.

    \image qml-toolbar-image-preview.png "Image preview dialog"

    \section1 Formatting Text

    The Qt Quick Toolbar for text allows you to edit the properties of
    \l{http://doc.qt.nokia.com/latest/qml-text.html}{Text} components.
    You can change the font family and size as well as text formatting, style,
    alignment, and color.

    If a property is assigned an expression instead of a value, you
    cannot use the toolbar to edit it. The button for editing the property
    is disabled.

    \image qml-toolbar-text.png "Qt Quick Toolbar for text"

    By default, font size is specified as pixels. To use points, instead,
    change \gui px to \gui pt in the size field.

    \section1 Previewing Animation

    The Qt Quick Toolbar for animation allows you to edit the properties of
    \l{http://doc.qt.nokia.com/4.7/qml-propertyanimation.html}{PropertyAnimation}
    components and the components that inherit it. You can change the easing curve
    type and duration. For some curves, you can also specify amplitude, period,
    and overshoot values.

    \image qml-toolbar-animation.png "Qt Quick Toolbar for animation"

    Select the play button to preview your changes.

    \section1 Editing Rectangles

    The Qt Quick Toolbar for rectangles allows you to edit the properties of

    \title Using the Maemo Emulator

    The Maemo emulator emulates the Nokia N900 device environment. You can test
    applications in conditions practically identical to running the application
    on a Nokia N900 device with software update release 1.2 (V10.2010.19-1).
    You can test user interaction by using the keypad and
    touch emulation.

    To test the application UI, user interaction with the application, and
    functionality that uses the mobility APIs, use the Qt Simulator,
    instead. For more information, see the
    \l{http://doc.qt.nokia.com/qt-simulator-beta/index.html}{Qt Simulator Manual}.

    The Maemo emulator is installed and configured as part of the \QSDK
    package. You can also install and configure the MADDE environment and
    Maemo emulator separately. For more information, see
    \l{Setting Up Development Environment for Maemo}.

    \section1 Starting the Maemo Emulator

    The \gui {Start Maemo Emulator} button is visible if you have a project
    open in Qt Creator for which you have added the Maemo build target
    and if you have configured a connection between Qt Creator and the Maemo
    Emulator.

    To start the Maemo emulator:

    \list 1

    \o Click
    \inlineimage qtcreator-maemo-emulator-button.png "Start Maemo Emulator button"
    .

    \o Select \gui {Mad Developer} on the Maemo emulator, to start the Mad Developer
    application

    \o If you have not deployed an SSH key to protect the connection between
    Qt Creator and the Maemo emulator, select \gui {Developer Password} to generate
    a password.

    \o In Qt Creator, enter the password in the connection settings:
    \gui {Tools > Options... > Projects > Maemo Device Configurations}.

    \endlist

    Test your application on the Maemo emulator as on a device. For a list of
    keyboard shortcuts that you can use to emulate Nokia N900 keys and functions, see

    \title Adding Qt Designer Plugins

     You can use Qt APIs to create plugins that extend Qt applications.
     This allows you to add your own widgets to \QD.
     The most flexible way to include a plugin with an application is to compile it
     into a dynamic library that is shipped separately, and detected and loaded at runtime.

     The applications can detect plugins that are stored in the standard plugin
     subdirectories. For more information on how to create and locate plugins and to
     change the default plugin path, see \l{How to Create Qt Plugins}.

     For more information about how to create plugins for \QD, see
     \l{http://doc.qt.nokia.com/4.7/designer-using-custom-widgets.html}{Creating and Using Components for Qt Designer}.

    \section1 Locating Qt Designer Plugins

     \QD fetches plugins from the standard locations and loads the plugins
     that match its build key. \QD is delivered both as a standalone application
     and as part of the SDK, where it is integrated into Qt Creator.
     The correct folder to place the plugins depends on
     which one you use.

     The integrated \QD fetches plugins from the \c {%SDK%\bin\designer} folder on Windows
     and Linux. For information about how to configure plugins on Mac OS, see
     \l{Configuring Qt Designer Plugins on Mac OS}.

     To check which plugins
     were loaded successfully and which failed, choose \gui{Tools > Form Editor >
     About Qt Designer Plugins}.

     The standalone \QD is part of the Qt library used for building projects,
     located under \c {%SDK%\qt}. Therefore, it fetches plugins from the following folder:
     \c {%SDK%\qt\plugins\designer}. To check which plugins were loaded successfully and which
     failed, choose \gui{Help > About Plugins}.

     \section2 Configuring Qt Designer Plugins on Mac OS

     On the Mac, a GUI application must be built and run from a bundle. A bundle is a
     directory structure that appears as a single entity when viewed in the Finder.
     A bundle for an application typcially contains the executable and all the resources
     it needs.

     Qt Creator uses its own set of Qt Libraries located in the bundle, and therefore,
     you need to configure the \QD plugins that you want to use with Qt Creator.
     Fore more information about how to deploy applications on Mac OS, see
     \l{http://doc.qt.nokia.com/4.7/deployment-mac.html}{Deploying an Application on Mac OS X}.

     The following example illustrates how to configure version 5.2.1 of the
     \l{http://qwt.sourceforge.net/}{Qwt - Qt Widgets for Technical Applications} library
     for use with Qt Creator:

     \list 1

    \o To check the paths used in the Qwt library, enter the following \c otool command:

    \snippet examples/doc_src_plugins.qdoc 0

    The output for Qwt 5.2.1 indicates that the plugin uses Qt core libraries (QtDesigner,
    QtScript, QtXml, QtGui and QtCore) and libqwt.5.dylib:

    \snippet examples/doc_src_plugins.qdoc 1


     \o You must copy the \QD plugin and the Qwt library files to the following locations:

                 \list
                 \o \c {libqwt_designer_plugin.dylib} to \c {QtCreator.app/Contents/MacOS/designer}
                 \o \c {libqwt.*.dylib} to \c {QtCreator.app/Contents/Frameworks}
                 \endlist

    Enter the following commands:

    \snippet examples/doc_src_plugins.qdoc 4

    \o Enter the following \c otool command to check the libraries that are used by the
    Qwt library:

    \snippet examples/doc_src_plugins.qdoc 2

    The command returns the following output:

    \snippet examples/doc_src_plugins.qdoc 3

    \o Enter the following \c install_name_tool command to fix the references of the
    libraries:

    \snippet examples/doc_src_plugins.qdoc 5

    \endlist


     \section1 Matching Build Keys

     The Qt Creator that is included in pre-built SDK packages on Windows is built with the
     Microsoft Visual Studio compiler, whereas the version of Qt shipped for building applications
     is configured and built to use the MinGW/g++ compiler. Plugins built by using this version of
     Qt cannot be loaded by Qt Creator because the build-keys do not match. The plugins can only be
     used in the standalone version of \QD. Choose \gui{Help > About Qt Creator} to check
     the Qt version Qt Creator was built with.

     To use \QD plugins that were built for the shipped Qt version, make sure that
     Qt Creator is built with the same compiler by either recompiling Qt Creator using MinGW or
     recompiling Qt with Microsoft Visual Studio, depending on which configuration you want to
     use for your applications.

    \title Optimizing Applications for Mobile Devices

    Before starting application development, analyze and define the requirements, scope, and
    functionality of the application to ensure efficient functionality and a smooth user
    experience. Design the application for a single purpose and analyze how it can best serve
    its users. Mobile devices have been designed for use when mobile. Keep the characteristics
    of mobile devices in mind when you create applications for them.

    The following guidelines help you design and develop usable applications for mobile devices
    with varying characteristics, such as screen size and support for input methods:

    \list

        \o Know your users

        Find out who will use the application, what they will use it for,
        and which mobile devices they have. Then design the application to fit a specific context
        of use.

        \o Design for small screens

        The screen size of mobile devices is significantly smaller
        than that available on desktop devices. Carefully consider what is the most relevant
        content to present on the application UI, as it might not be reasonable to try and fit as
        much content into the screen as you might have in a desktop application.

       \o Design for multiple screen sizes

       Relate the position and size of each control to the
       dimensions of the display. This enables the same set of information to be presented on the
       screen in all resolutions; higher resolution devices just display finer graphics.

       \o Design for changing screen orientation

       Some devices support screen rotation. On these
       devices, applications can be displayed in portrait or landscape orientation. Account for
       orientation and dynamically adjust the display when the screen is rotated.

       \o Design intuitive ways of moving within applications

       Mobile devices lack a mouse and
       full-size keyboard, so users must use the touch screen or five way navigation pad to move within
       applications. In addition, many users control the devices with one hand. To create an optimized user
       experience, allow users to access information with one click; do not make them scroll and type.

       \o Design for limited input methods

       Applications collect information from users on the task
       at hand. In addition to touch screen input, some devices contain physical keys such
       as a five way navigation pad, a keypad, and a keyboard. Users enter information by using screen
       controls, such as lists, check boxes, radio buttons, and text fields.

       \o Keep response times short

       Latency can cause delays in user interaction. If users perceive
       an application as being slow, they are likely to get frustrated and stop using it.

       \o Save battery time

       Mobile devices are not constantly connected to a power source but run on
       battery power. Optimize power consumption to keep the total consumption at an acceptable
       level and to prevent users from running out of battery time.

       For more information and code examples on how to minimize power consumption, see
       \l{http://developer.symbian.org/wiki/index.php/Creating_Energy_Efficient_Apps_Using_Qt}{Creating Energy Efficient Apps Using Qt}.

       \o Consider network issues

       If users do not have a flat-rate data plan or WLAN support, mobile
       network connections cost them money. Also, when users move around with the devices, the networks
       available for connections constantly change.

       \o Remember the processing limits of the device

       The memory available on devices is limited
       and you should use it carefully. Although all mobile devices have common functionality,
       each device is individual in terms of both the resources available and extra features.
       Therefore, you must consider the constraints of all the target devices.

       \endlist

       For more information about user experience techniques for mobile devices, see the
       \l{http://library.forum.nokia.com/topic/Design_and_User_Experience_Library/GUID-A8DF3EB8-E97C-4DA0-95F6-F464ECC995BC_cover.html}{Design and User Experience Library}

    \title Tips and Tricks


    \section1 Switching Between Modes

    Qt Creator uses different modes for different purposes. You can quickly
    switch between these modes with the following keyboard shortcuts:
    \list
        \o \gui Welcome mode \key Ctrl+1
        \o \gui Edit mode \key Ctrl+2
        \o \gui Design mode \key Ctrl+3
        \o \gui Debug mode \key Ctrl+4
        \o \gui Projects mode \key Ctrl+5
        \o \gui Help mode \key Ctrl+6
    \endlist


    For more information about Qt Creator modes, see \l {Qt Creator Modes}.



    \section1 Moving Between Open Files

    To quickly move between currently open files, press
    \key Ctrl+Tab.

    To move forward in the location history, press \key {Alt+Right}
    (\key {Cmd+Opt+Right} on Mac OS). To move backward, press \key {Alt+Left}
    (\key {Cmd+Opt+Left} on Mac OS). For example, if you use the \gui Locator
    to jump to a symbol in the same file, you can jump back to your original
    location in that file by pressing \key {Alt+Left}.


    \section1 Moving To the Edit Mode

    To move to the \gui Edit mode and currently active file, press
    \key Esc.

    If you already are in the \gui Edit mode:
    \list
        \o The first press moves focus to the editor
        \o The second press closes secondary windows
    \endlist

    \section1 Using the Filter in Options Dialog

    To find specific settings you require in \gui{Tools} > \gui{Options...}
    use the filter located at the top left of the \gui Options dialog box.

    \section1 Opening Output Panes

    The output panes provide a list of errors and warnings encountered during
    a build, detailed output from the compiler, status of a program when it is
    executed and debug output, as well as search results.

    To open output panes, use the following shortcuts:

    \list

        \o \gui{Build Issues} pane Alt+1 (Cmd+1 on Mac OS X)

        \o \gui{Search Results} pane Alt+2 (Cmd+2 on Mac OS X)

        \o \gui{Application Output} pane Alt+3 (Cmd+3 on Mac OS X)

        \o \gui{Compile Output} pane Alt+4 (Cmd+4 on Mac OS X)

    \endlist

    For more information about output panes, see \l{Viewing Output}.


    \section1 Using Keyboard Shortcuts

    Qt Creator provides \l{Keyboard Shortcuts}{many useful keyboard shortcuts}.
    You can see the keyboard shortcut for a menu command in the menu
    or the tooltip for a button.

    To customize, import or export keyboard shortcuts, select \gui Tools >
    \gui Options... > \gui Environment > \gui Keyboard.


    \section1 Running Qt Creator From Command Line

    You can launch Qt Creator from command line using the name of an
    existing session or \c .pro file by giving the name as the command
    argument.

    For example, running \tt{qtcreator somesession}, launches Qt Creator and
    loads session somesession.

    \note Make sure Qt Creator is included in the PATH environment variable.
    This can be done by typing the following in the command line:
    \code
    set PATH=c:\qtsdk\mingw\bin;c:\qtsdk\qt\bin;%PATH%
    \endcode


    \section1 Showing and Hiding the Sidebar

    To toggle the sidebar in the \gui Edit and \gui Debug modes, click
    \inlineimage qtcreator-togglebutton.png
    or press \key Alt+0 (\key Cmd+0 on Mac OS X).

    For more information on using the sidebar, see \l {Browsing Project Contents}.



    \section1 Moving To Symbols

    To move straight to a symbol used in a project, select the symbol in the
    \gui Editor toolbar drop-down menu. For more information on the editor toolbar,
    see \l {Using the Editor Toolbar}.

    To jump to a symbol in the current file, press \key {Ctrl+K} to open the
    \gui Locator, enter a period (.), and start typing the symbol name. Then
    select the symbol in the list. For more information on using the locator,
    see \l{Searching With the Locator}.

    Press \key Ctrl (\key Cmd on Mac OS) and click a symbol to move directly to
    the definition or the declaration of the symbol. You can also move the cursor
    on the symbol and press \key {F2}. For more information, see
    \l{Moving to Symbol Definition or Declaration}.



    \section1 Displaying Signals and Slots

    If an instance of a class is derived from QObject, and you would like to
    find all other objects connected to one of your object's slots using
    Qt's signals and slots mechanism, select \gui Tools > \gui Options...
    > \gui{Debugger} > \gui{Debugging Helper} > \gui{Use Debugging Helper}.

    In the \gui{Locals and Watchers} view, expand the object's entry and open
    the slot in the \e slots subitem. The objects connected to this slot are
    shown as children of the slot. This method works with signals too.

    For more information about the \gui{Locals and Watchers} view, see
    \l{Locals and Watchers}.


    \section1 Displaying Low Level Data

    If special debugging of Qt objects fails due to data corruption within the
    debugged objects, you can switch off the debugging helpers. When debugging
    helpers are switched off low-level structures become visible.

    To switch off the debugging helpers:
    \list 1
        \o Select \gui Tools > \gui Options... > \gui Debugger >
           \gui{Debugging Helper}.
        \o Uncheck the \gui{Use Debugging Helper} checkbox.
    \endlist

    \section1 Showing Tooltips in Debug Mode

    To inspect the value of variables from the editor, you can turn
    on tooltips. Tooltips are hidden by default for performance reasons.

    \list 1
        \o Select \gui Tools > \gui Options... > \gui Debugger > \gui General.
        \o Select the \gui {Use tooltips in main editor while debugging} check box.
    \endlist

    \section1 Locating Files

    The \gui Locator provides one of the easiest ways in Qt Creator to browse
    through projects, files, classes, methods, documentation and file systems.
    To quickly access files not directly mentioned in your project, you can
    create your own locator filters. That way you can locate files in a
    directory structure you have defined.

    To create locator filters, select \gui {Tools > Options... > Locator > Add}.

    For more information, see \l{Creating Locator Filters}.

    \section1 Adding a License Header Template for C++ Code

    A file containing a license header for C++ can be specified under
    \gui{Tools > Options... > C++ > License Template}. It may contain special
    placeholders enclosed in \c{%%} that are replaced when generating a
    new file:

    \list 1
        \o \c %YEAR%: Year
        \o \c %MONTH%: Month
        \o \c %DAY%: Day of the month
        \o \c %DATE%: Date
        \o \c %USER%: User name
        \o \c %FILENAME%: File name
        \o \c %CLASS%: Class name (if applicable)
        \o \c %$VARIABLE%: Contents of environment variable \c{VARIABLE}.
    \endlist

    \title Known Issues

    This section lists known issues in Qt Creator version 2.1.0.
    The development team is aware of them, and therefore, you do not need to
    report them as bugs.

    For a list of fixed issues and added features, see the changelog file in
    the \c{qtcreator\dist} folder or the \l{http://bugreports.qt.nokia.com}{Qt Bug Tracker}.

    \section1 General Issues

    \list

        \o Qt Creator uses SQLite for storing some of its settings. SQLite is
           known to have problems with certain NFS servers (most notably the
           nfs-user-server 2.2beta), since they can lock up the application
           when it tries to lock the database. If your home directory is on an
           NFS share and you encounter this issue, one option would be to
           switch to the nfs-kernel-server, or create a symlink so that the
           settings are stored locally.

    \endlist

    \section1 Editing Issues

    \list

        \o Code completion does not support typedefs for nested classes.

    \endlist

    \section1 Projects Issues

    \list
        \o Paths or file names containing spaces or special characters
           (such as colons, dollar signs, and hash marks) may cause problems. This
           is because some of the tools Qt Creator uses in the background have
           restrictions on the characters allowed in file and directory names.
           To be on the safe side, we recommend creating projects and project
           items with names consisting of plain characters, numbers,
           underscores, and hyphens.

        \o There is no IDE support for adding or removing subprojects. Project
           hierarchies (SUBDIRS template) have to be created manually.

        \o Creating new CMake projects with Qt Creator is not supported.

        \o Building and packaging subprojects is not supported for Maemo devices.

        \o You must create projects for Maemo targets on the same partition where
        you installed \QSDK, Qt Creator, and MADDE.

        \o If error messages displayed in the \gui {Compile Output} pane contain
        paths where slashes are missing (for example, C:QtSDK),
        check your PATH variable. For more information, see
        \l{Troubleshooting MinGW Compilation Errors}.

    \endlist

    \section1 Debugging Issues

    \list

        \o Debugging large applications on Symbian devices using the Symbian S^3
           operating system might not work, because the TRK debug agent might not be able to
           access memory when the operating system starts paging. This causes breakpoint
           handling and symbol resolution to fail. For more information, see
           \l{http://bugreports.qt.nokia.com/browse/QTCREATORBUG-2158}{QTCREATORBUG-2158}.

           As a workaround, add the following section to the application .pro file to
           disable paging:

           \code
           debug {
               MMP_RULES -= PAGED
               MMP_RULES *= UNPAGED
           }
           \endcode

           \note You must completely clean and rebuild the project for the setting to
           take effect.

        \o When debugging executables created by the GNU Compiler version 4.5.0
           (all platforms), some data types will not be displayed in the
           \gui{Locals and Watchers} view due to missing debug information.

        \o Gdb on Windows may not work if the 'Embassy \reg Security Center' software
           by 'Wave \reg Systems' is installed and active (causing crashes in \c{vxvault.dll)}).

        \o Gdb may take long to load debugging symbols, especially from large
           libraries like \c libQtWebKit. Starting the debugging module can
           take up to several minutes without visible progress.

        \o Setting breakpoints in code that is compiled into the binary more
           than once does not work.

        \o Setting breakpoints in files that do not have unique absolute
           paths may fail. For example, remounting parts of a file system
           using the --bind mount option.

    \title Creating Task List Files

    You can load tasks from task lists to the \gui{Build Issues} pane. You can
    either create the task lists manually or create scripts to generate them from
    output of static code analysis tools, for example.

    For an example of a script that checks new lines of code and matches them
    against regular expressions to generate a task list, see \c{scripts\mytasks.pl}
    in the Qt Creator repository.

    \section1 Task List File Format

    The filename extension must be .tasks for Qt Creator to recognize a file as a
    task list file.

    Each line in a task list file is treated as a tab-separated list of strings with
    \c{\t}, \c{\n}, and \c{\\} used as escape characters. The strings are used to create
    one task per line. The lines can have one of the following formats:

    \list

    \o \c description

    \o \c{type\tdescription}

    \o \c{file\ttype\tdescription}

    \o \c{file\tline\ttype\tdescription}

    \endlist

    The task type can have one of the following values:

    \list

    \o A string starting with \c err, which displays the error icon in the beginning of the line
    \o A string starting with \c warn, which displays the warning icon
    \o Any other value, which sets the task type to Unknown and does not
    display an icon

    \endlist

    The values are not case sensitive.

    Lines starting with the hash mark character (#) in the first column are ignored.
