overview = """\
A demo of using wxMenuBar and wxMenu in various ways.

A menu is a popup (or pull down) list of items, one of which may be selected 
before the menu goes away (clicking elsewhere dismisses the menu). Menus may be 
used to construct either menu bars or popup menus.

A menu item has an integer ID associated with it which can be used to identify 
the selection, or to change the menu item in some way. A menu item with a special 
identifier -1 is a separator item and doesn't have an associated command but just 
makes a separator line appear in the menu.

Menu items may be either normal items, check items or radio items. Normal items 
don't have any special properties while the check items have a boolean flag associated 
to them and they show a checkmark in the menu when the flag is set. wxWindows 
automatically toggles the flag value when the item is clicked and its value may 
be retrieved using either IsChecked method of wxMenu or wxMenuBar itself or by 
using wxEvent.IsChecked when you get the menu notification for the item in question.

The radio items are similar to the check items except that all the other items 
in the same radio group are unchecked when a radio item is checked. The radio group 
is formed by a contiguous range of radio items, i.e. it starts at the first item of 
this kind and ends with the first item of a different kind (or the end of the menu). 
Notice that because the radio groups are defined in terms of the item positions 
inserting or removing the items in the menu containing the radio items risks to not 
work correctly. Finally note that the radio items are only supported under Windows 
and GTK+ currently.
