\section{\class{wxMenu}}\label{wxmenu}
A menu is a popup (or pull down) list of items, one of which may be
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.
+{\bf NB:} Please note that {\it wxID\_ABOUT} and {\it wxID\_EXIT} are
+predefined by wxWidgets and have a special meaning since entries
+using these IDs will be taken out of the normal menus under MacOS X
+and will be inserted into the system menu (following the appropriate
+MacOS X interface guideline). On PalmOS {\it wxID\_EXIT} is disabled according
+to Palm OS Companion guidelines.
+
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
+wxWidgets automatically toggles 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
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

as your EVT\_MENU entries, events from the toolbar will also be processed by your
EVT\_MENU event handlers.
-Note that menu commands (and UI update events for menus) are first sent to
-the focus window within the frame. If no window within the frame has the focus,
-then the events are sent directly to the frame. This allows command and UI update
-handling to be processed by specific windows and controls, and not necessarily
-by the application frame.
-
{\bf Tip:} under Windows, if you discover that menu shortcuts (for example, Alt-F to show the file menu)
are not working, check any EVT\_CHAR events you are handling in child windows.
If you are not calling {\tt event.Skip()} for events that you don't process in these event handlers,
