Menus allow
users to view or choose from a list of choices and commands that your application
provides. You can use the Menu Manager to create, display, and manage the
drawing and behavior of pull-down, hierarchical, and contextual menus. Carbon
introduces changes to the Menu Manager, including new Apple menu behavior,
opaque menu data, universal command IDs for accessing menu item data, Carbon
MDEFs, and new APIs for working with menu and menu item attributes and for
enabling and disabling menu items. |
