+# 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.
+#

+#----------------------------------------------------------------------

+#
+# 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.
