     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.

+
+    All menus must be created on the @b heap because all menus attached to a

+    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

+

+
+    With a popup menu (see wxWindow::PopupMenu), there is a variety of ways to
+    handle a menu selection event (@c wxEVT_COMMAND_MENU_SELECTED):
+    - 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.
