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.
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 togles the flag value when the item is clicked and its
value may be retrieved using either \helpref{IsChecked}{wxmenuischecked} method
of wxMenu or wxMenuBar itself or by using
\helpref{wxEvent::IsChecked}{wxcommandeventischecked} 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.
