    @class wxMenuBar

    A menu bar is a series of menus accessible from the top of a frame.

    @remarks
    To respond to a menu selection, provide a handler for EVT_MENU, in the frame
    that contains the menu bar.

    If you have a toolbar which uses the same identifiers as your EVT_MENU entries,
    events from the toolbar will also be processed by your EVT_MENU event handlers.

    Tip: under Windows, if you discover that menu shortcuts (for example, Alt-F
    to show the file menu) are not working, check any EVT_CHAR events you are
    handling in child windows.
    If you are not calling event.Skip() for events that you don't process in
    these event handlers, menu shortcuts may cease to work.

/**
    @class wxMenu

    A menu is a popup (or pull down) list of items, one of which may be
    selected before the menu goes away (clicking elsewhere dismisses the
    menu). Menus may be used to construct either menu bars or popup menus.

    A menu item has an integer ID associated with it which can be used to
    identify the selection, or to change the menu item in some way. A menu item
    with a special identifier @e wxID_SEPARATOR is a separator item and doesn't
    have an associated command but just makes a separator line appear in the
    menu.

    @note
    Please note that @e wxID_ABOUT and @e wxID_EXIT are predefined by wxWidgets
    and have a special meaning since entries using these IDs will be taken out
    of the normal menus under OS X and will be inserted into the system menu
    (following the appropriate OS X interface guideline).

    Menu items may be either @e normal items, @e check items or @e radio items.
    Normal items don't have any special properties while the check items have a
    boolean flag associated to them and they show a checkmark in the menu when
    the flag is set.
    wxWidgets automatically toggles the flag value when the item is clicked and its
    value may be retrieved using either wxMenu::IsChecked method of wxMenu or
    wxMenuBar itself or by using wxEvent::IsChecked when you get the menu
    notification for the item in question.

    The radio items are similar to the check items except that all the other items
    in the same radio group are unchecked when a radio item is checked. The radio
    group is formed by a contiguous range of radio items, i.e. it starts at the
    first item of this kind and ends with the first item of a different kind (or
    the end of the menu). Notice that because the radio groups are defined in terms
    of the item positions inserting or removing the items in the menu containing
    the radio items risks to not work correctly.


    @section menu_allocation Allocation strategy

    All menus must be created on the @b heap because all menus attached to a
    menubar or to another menu will be deleted by their parent when it is
    deleted. The only exception to this rule are the popup menus (i.e. menus
    used with wxWindow::PopupMenu()) as wxWidgets does not destroy them to
    allow reusing the same menu more than once. But the exception applies only
    to the menus themselves and not to any submenus of popup menus which are
    still destroyed by wxWidgets as usual and so must be heap-allocated.

    As the frame menubar is deleted by the frame itself, it means that normally
    all menus used are deleted automatically.


    @section menu_eventhandling Event handling

    If the menu is part of a menubar, then wxMenuBar event processing is used.

    With a popup menu (see wxWindow::PopupMenu), there is a variety of ways to
    handle a menu selection event (@c wxEVT_MENU):
    - Provide @c EVT_MENU handlers in the window which pops up the menu, or in an
      ancestor of that window (the simplest method);
    - Derive a new class from wxMenu and define event table entries using the @c EVT_MENU macro;
    - Set a new event handler for wxMenu, through wxEvtHandler::SetNextHandler,
      specifying an object whose class has @c EVT_MENU entries;

    Note that instead of static @c EVT_MENU macros you can also use dynamic
    connection; see @ref overview_events_bind.
