MyUniqueMenuID

Allocates a new menu ID. This is how you would define your menu ID allocation function if you were to name it MyUniqueMenuID:

typedef SInt16 MyUniqueMenuID (
                     JMAWTContextRef context,
                     Boolean isSubmenu);

context

The AWT context containing the frame.

isSubMenu

A Boolean value. If false, the menu to add is a standard menu. If true, the menu is a submenu. The menu ID value of a submenu must be in the range 1 to 255.

function result

If successful, the function should return the ID of the new menu. Otherwise the function returns 0.

DISCUSSION

When instantiating an AWT context, you must designate a callback function to create new menu IDs if necessary.
