** This demo shows the use of MUI's menus classes.
*/
#include "demo.h"
/*
** MUI still supports the use of a conventional gadtools NewMenu structure
** to define a menu strip. The address of this structure is passed to a
** MUI_MakeObject(MUIO_MenustripNM,newmenu,0) function which creates a complete
** object tree for this menu and returns a pointer to the menustrip object,
** This pointer should be placed in a windows MUIA_Window_Menustrip attribute
** or in an applications MUIA_Application_Menustrip attribute, in which case
** all windows will inherit the menu. To get direct access to the menu item
** objects of such an auto generated tree, you can use the MUIM_FindUserData
** method.
**
** You can of course create the menu object tree yourself by defining
** a menu strip object with some menu object children with some menu
** item object children with optionally some more menu item object
** children. In this case, use the MUI_MakeObject(MUIO_Menuitem,...)
** call to create the menu items if possible.
**
** The main program shows some different methods how to create items and
** how to react on menu items. Choose the one you like best, and don't
** forget the MUIM_CallHook method if you dislike switch/case in the
** main loop!
