10 @class wxMenuBar
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.

372 @class wxMenu
373
374 A menu is a popup (or pull down) list of items, one of which may be
375 selected before the menu goes away (clicking elsewhere dismisses the
376 menu). Menus may be used to construct either menu bars or popup menus.
377
378 A menu item has an integer ID associated with it which can be used to
379 identify the selection, or to change the menu item in some way. A menu item
380 with a special identifier -1 is a separator item and doesn't have an
381 associated command but just makes a separator line appear in the menu.
382
383 @note
384 Please note that @e wxID_ABOUT and @e wxID_EXIT are predefined by wxWidgets
385 and have a special meaning since entries using these IDs will be taken out
386 of the normal menus under MacOS X and will be inserted into the system menu
387 (following the appropriate MacOS X interface guideline).
388 On PalmOS @e wxID_EXIT is disabled according to Palm OS Companion guidelines.
389
390 Menu items may be either normal items, check items or radio items.
391 Normal items don't have any special properties while the check items have a
392 boolean flag associated to them and they show a checkmark in the menu when
393 the flag is set.
394 wxWidgets automatically toggles the flag value when the item is clicked and its
395 value may be retrieved using either wxMenu::IsChecked method of wxMenu or
396 wxMenuBar itself or by using wxEvent::IsChecked when you get the menu
397 notification for the item in question.
398
399 The radio items are similar to the check items except that all the other items
400 in the same radio group are unchecked when a radio item is checked. The radio
401 group is formed by a contiguous range of radio items, i.e. it starts at the
402 first item of this kind and ends with the first item of a different kind (or
403 the end of the menu). Notice that because the radio groups are defined in terms
404 of the item positions inserting or removing the items in the menu containing
405 the radio items risks to not work correctly. Finally note that radio items
406 are not supported under Motif.
407
408
409 @section menu_allocation Allocation strategy
410
411 All menus except the popup ones must be created on the heap.
412 All menus attached to a menubar or to another menu will be deleted by their
413 parent when it is deleted.
414 As the frame menubar is deleted by the frame itself, it means that normally
415 all menus used are deleted automatically.
416
417
418 @section menu_eventhandling Event handling
419
420 If the menu is part of a menubar, then wxMenuBar event processing is used.
421 With a popup menu, there is a variety of ways to handle a menu selection event
422 (wxEVT_COMMAND_MENU_SELECTED).
423 Derive a new class from wxMenu and define event table entries using the EVT_MENU macro.
424 Set a new event handler for wxMenu, using an object whose class has EVT_MENU entries.
425 Provide EVT_MENU handlers in the window which pops up the menu, or in an
426 ancestor of this window.

491 by a TAB character ('\\t').
492
493 Its general syntax is any combination of "CTRL", "ALT" and "SHIFT" strings
494 (case doesn't matter) separated by either '-' or '+' characters and followed
495 by the accelerator itself.
496 The accelerator may be any alphanumeric character, any function key
