- # Focus Group
- #
- # Focus groups are used to handle the user's focusing actions inside a
- # toplevel.
- #
- # One example of using focus groups is: when the user focuses on an
- # entry, the text in the entry is highlighted and the cursor is put to
- # the end of the text. When the user changes focus to another widget,
- # the text in the previously focused entry is validated.
- #
-
- #----------------------------------------------------------------------
- # tkFocusGroup_Create --
- #
- # Create a focus group. All the widgets in a focus group must be
- # within the same focus toplevel. Each toplevel can have only
- # one focus group, which is identified by the name of the
- # toplevel widget.
