  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.

 371     @class wxMenu
 372
 373     A menu is a popup (or pull down) list of items, one of which may be
 374     selected before the menu goes away (clicking elsewhere dismisses the
 375     menu). Menus may be used to construct either menu bars or popup menus.
 376
 377     A menu item has an integer ID associated with it which can be used to
 378     identify the selection, or to change the menu item in some way. A menu item
 379     with a special identifier -1 is a separator item and doesn't have an
 380     associated command but just makes a separator line appear in the menu.
 381
 382     @note
 383     Please note that @e wxID_ABOUT and @e wxID_EXIT are predefined by wxWidgets
 384     and have a special meaning since entries using these IDs will be taken out
 385     of the normal menus under MacOS X and will be inserted into the system menu
 386     (following the appropriate MacOS X interface guideline).
 387     On PalmOS @e wxID_EXIT is disabled according to Palm OS Companion guidelines.
 388
 389     Menu items may be either @e normal items, @e check items or @e radio items.
 390     Normal items don't have any special properties while the check items have a
 391     boolean flag associated to them and they show a checkmark in the menu when
 392     the flag is set.
 393     wxWidgets automatically toggles the flag value when the item is clicked and its
 394     value may be retrieved using either wxMenu::IsChecked method of wxMenu or
 395     wxMenuBar itself or by using wxEvent::IsChecked when you get the menu
 396     notification for the item in question.
 397
 398     The radio items are similar to the check items except that all the other items
 399     in the same radio group are unchecked when a radio item is checked. The radio
 400     group is formed by a contiguous range of radio items, i.e. it starts at the
 401     first item of this kind and ends with the first item of a different kind (or
 402     the end of the menu). Notice that because the radio groups are defined in terms
 403     of the item positions inserting or removing the items in the menu containing
 404     the radio items risks to not work correctly.
 405
 406
 407     @section menu_allocation Allocation strategy
 408
 409     All menus except the popup ones must be created on the @b heap.
 410     All menus attached to a menubar or to another menu will be deleted by their
 411     parent when it is deleted.
 412
 413     As the frame menubar is deleted by the frame itself, it means that normally
 414     all menus used are deleted automatically.
 415
 416
 417     @section menu_eventhandling Event handling
 418
 419     If the menu is part of a menubar, then wxMenuBar event processing is used.
 420
 421     With a popup menu (see wxWindow::PopupMenu), there is a variety of ways to
 422     handle a menu selection event (@c wxEVT_COMMAND_MENU_SELECTED):
 423     - Provide @c EVT_MENU handlers in the window which pops up the menu, or in an
 424       ancestor of that window (the simplest method);
 425     - Derive a new class from wxMenu and define event table entries using the @c EVT_MENU macro;
 426     - Set a new event handler for wxMenu, through wxEvtHandler::SetNextHandler,
 427       specifying an object whose class has @c EVT_MENU entries;
 428
 429     Note that instead of static @c EVT_MENU macros you can also use dynamic
 430     connection; see @ref overview_eventhandling_connect.

 497         (case doesn't matter) separated by either '-' or '+' characters and followed
