Menu Definition IDs

CHANGED WITH THE APPEARANCE MANAGER

A menu definition ID is supplied to the menu resource or a menu-creation function such as NewMenu to specify which menu definition function to use in creating the menu. The menu definition ID contains the resource ID of the menu definition function.

When mapping is enabled, the pre-Appearance menu definition ID textmenuProc will be mapped to kMenuStdMenuProc, its Appearance-compliant equivalent. For a discussion on how to enable mapping, see "Introduction to the Appearance Manager".

enum {            
   textmenuProc        = 0,
   kMenuStdMenuProc    = 63,
   kMenuStdMenuBarProc = 63
};
