  9. ** MUI still supports the use of a conventional gadtools NewMenu structure
  10. ** to define a menu strip. The address of this structure is passed to a
  11. ** MUI_MakeObject(MUIO_MenustripNM,newmenu,0) function which creates a complete
  12. ** object tree for this menu and returns a pointer to the menustrip object,
  13. ** This pointer should be placed in a windows MUIA_Window_Menustrip attribute
  14. ** or in an applications MUIA_Application_Menustrip attribute, in which case
  15. ** all windows will inherit the menu. To get direct access to the menu item
  16. ** objects of such an auto generated tree, you can use the MUIM_FindUserData
  17. ** method.
  18. **
  19. ** You can of course create the menu object tree yourself by defining
  20. ** a menu strip object with some menu object children with some menu
  21. ** item object children with optionally some more menu item object
  22. ** children. In this case, use the MUI_MakeObject(MUIO_Menuitem,...)
  23. ** call to create the menu items if possible.
  24. **
  25. ** The main program shows some different methods how to create items and
  26. ** how to react on menu items. Choose the one you like best, and don't
  27. ** forget the MUIM_CallHook method if you dislike switch/case in the
  28. ** main loop!
