-
-$t insert end "A text widget can contain other widgets embedded "
-$t insert end "it. These are called \"embedded windows\", "
-$t insert end "and they can consist of arbitrary widgets. "
-$t insert end "For example, here are two embedded button "

-$t window create end -window $t.on
-$t insert end " horizontal scrolling, which also turns off "

-$t insert end "button to\n"
-$t window create end -window $t.off
-$t insert end " horizontal scrolling and turn back on word wrapping.\n\n"

-$t insert end "of the 'parent', but many of the embedded windows, "
-$t insert end "such as buttons will not be there. The easiest way "
-$t insert end "to ensure they are in all peers is to use '-create' "
-$t insert end "embedded window creation scripts "
-$t insert end "(the plot above and the 'Make A Peer' button are "
-$t insert end "designed to show up in all peers). A good use of "
-$t insert end "peers is for "

-
-$t insert end "Users of previous versions of Tk will also be interested "
-$t insert end "to note that now cursor movement is now by visual line by "
-$t insert end "default, and that all scrolling of this widget is by pixel.\n\n"
-
-$t insert end "You may also find it useful to put embedded windows in "
-$t insert end "a text without any actual text. In this case the "
-$t insert end "text widget acts like a geometry manager. For "
-$t insert end "example, here is a collection of buttons laid out "
-$t insert end "neatly into rows by the text widget. These buttons "
-$t insert end "can be used to change the background color of the "
-$t insert end "text widget (\"Default\" restores the color to "
-$t insert end "its default). If you click on the button labeled "
-$t insert end "\"Short\", it changes to a longer string so that "
-$t insert end "you can see how the text widget automatically "
-$t insert end "changes the layout. Click on the button again "
-$t insert end "to restore the short string.\n"
