@section menu_eventhandling Event handling
If the menu is part of a menubar, then wxMenuBar event processing is used.
- With a popup menu, there is a variety of ways to handle a menu selection event
- (wxEVT_COMMAND_MENU_SELECTED).
- Derive a new class from wxMenu and define event table entries using the EVT_MENU macro.
- Set a new event handler for wxMenu, using an object whose class has EVT_MENU entries.
- Provide EVT_MENU handlers in the window which pops up the menu, or in an
- ancestor of this window.
