###
Module Summary

Functions for wxMenuBar class

###
Description

A menu bar is a series of menus accessible from the top of a frame.

Remark: To respond to a menu selection, provide a handler for EVT_MENU, in the frame that contains the menu bar.

If you have a toolbar which uses the same identifiers as your EVT_MENU entries, events from the toolbar will also be processed by your EVT_MENU event handlers.

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 event.Skip() for events that you don't process in these event handlers, menu shortcuts may cease to work.

See: wxMenu, Overview events

This class is derived (and can use functions) from: wxWindow wxEvtHandler
