  11
  12     A menu bar is a series of menus accessible from the top of a frame.
  13
  14     @remarks
  15     To respond to a menu selection, provide a handler for EVT_MENU, in the frame
  16     that contains the menu bar.
  17
  18     If you have a toolbar which uses the same identifiers as your EVT_MENU entries,
  19     events from the toolbar will also be processed by your EVT_MENU event handlers.
  20
  21     Tip: under Windows, if you discover that menu shortcuts (for example, Alt-F
  22     to show the file menu) are not working, check any EVT_CHAR events you are
  23     handling in child windows.
  24     If you are not calling event.Skip() for events that you don't process in
  25     these event handlers, menu shortcuts may cease to work.

 381     @class wxMenu
 382
 383     A menu is a popup (or pull down) list of items, one of which may be
 384     selected before the menu goes away (clicking elsewhere dismisses the
 385     menu). Menus may be used to construct either menu bars or popup menus.
 386
 387     A menu item has an integer ID associated with it which can be used to
 388     identify the selection, or to change the menu item in some way. A menu item
 389     with a special identifier -1 is a separator item and doesn't have an
 390     associated command but just makes a separator line appear in the menu.
 391
 392     @note
 393     Please note that @e wxID_ABOUT and @e wxID_EXIT are predefined by wxWidgets
 394     and have a special meaning since entries using these IDs will be taken out
 395     of the normal menus under MacOS X and will be inserted into the system menu
 396     (following the appropriate MacOS X interface guideline).
 397     On PalmOS @e wxID_EXIT is disabled according to Palm OS Companion guidelines.
 398
 399     Menu items may be either @e normal items, @e check items or @e radio items.
 400     Normal items don't have any special properties while the check items have a
 401     boolean flag associated to them and they show a checkmark in the menu when
 402     the flag is set.
 403     wxWidgets automatically toggles the flag value when the item is clicked and its
 404     value may be retrieved using either wxMenu::IsChecked method of wxMenu or
 405     wxMenuBar itself or by using wxEvent::IsChecked when you get the menu
 406     notification for the item in question.
 407
 408     The radio items are similar to the check items except that all the other items
 409     in the same radio group are unchecked when a radio item is checked. The radio
 410     group is formed by a contiguous range of radio items, i.e. it starts at the
 411     first item of this kind and ends with the first item of a different kind (or
 412     the end of the menu). Notice that because the radio groups are defined in terms
 413     of the item positions inserting or removing the items in the menu containing
 414     the radio items risks to not work correctly.
 415
 416
 417     @section menu_allocation Allocation strategy
 418
 419     All menus must be created on the @b heap because all menus attached to a
 420     menubar or to another menu will be deleted by their parent when it is
 421     deleted. The only exception to this rule are the popup menus (i.e. menus
 422     used with wxWindow::PopupMenu()) as wxWidgets does not destroy them to
 423     allow reusing the same menu more than once. But the exception applies only
 424     to the menus themselves and not to any submenus of popup menus which are
 425     still destroyed by wxWidgets as usual and so must be heap-allocated.
 426
 427     As the frame menubar is deleted by the frame itself, it means that normally
 428     all menus used are deleted automatically.
 429
 430
 431     @section menu_eventhandling Event handling
 432
 433     If the menu is part of a menubar, then wxMenuBar event processing is used.
 434
 435     With a popup menu (see wxWindow::PopupMenu), there is a variety of ways to
 436     handle a menu selection event (@c wxEVT_COMMAND_MENU_SELECTED):
 437     - Provide @c EVT_MENU handlers in the window which pops up the menu, or in an
 438       ancestor of that window (the simplest method);
 439     - Derive a new class from wxMenu and define event table entries using the @c EVT_MENU macro;
 440     - Set a new event handler for wxMenu, through wxEvtHandler::SetNextHandler,
 441       specifying an object whose class has @c EVT_MENU entries;
 442
 443     Note that instead of static @c EVT_MENU macros you can also use dynamic
 444     connection; see @ref overview_events_bind.
