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.

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 except the popup ones must be created on the @b heap.
420 All menus attached to a menubar or to another menu will be deleted by their
421 parent when it is deleted.
422
423 As the frame menubar is deleted by the frame itself, it means that normally
424 all menus used are deleted automatically.
425
426
427 @section menu_eventhandling Event handling
428
429 If the menu is part of a menubar, then wxMenuBar event processing is used.
430
431 With a popup menu (see wxWindow::PopupMenu), there is a variety of ways to
432 handle a menu selection event (@c wxEVT_COMMAND_MENU_SELECTED):
433 - Provide @c EVT_MENU handlers in the window which pops up the menu, or in an
434 ancestor of that window (the simplest method);
435 - Derive a new class from wxMenu and define event table entries using the @c EVT_MENU macro;
436 - Set a new event handler for wxMenu, through wxEvtHandler::SetNextHandler,
437 specifying an object whose class has @c EVT_MENU entries;
438
439 Note that instead of static @c EVT_MENU macros you can also use dynamic
440 connection; see @ref overview_events_bind.

501 may include the accelerator which can be used to activate the menu item
502 from keyboard.
503 The accelerator string follows the item label and is separated from it
504 by a TAB character ('\\t').
505
506 Its general syntax is any combination of "CTRL", "ALT" and "SHIFT" strings
507 (case doesn't matter) separated by either '-' or '+' characters and followed
508 by the accelerator itself.
