pure virtual

Remarks: This method is used internally.

This method sets a new context for the menu, invalidating the menu's cache.

Parameters:: IMenuGlobalContext* pIMenuGlobalContext

Points to the context to set.

virtual IMenuLocalContext* GetIMenuLocalContext ( )

pure virtual

Remarks: This method is used internally.

Returns a pointer to the menu's local context.

virtual int NumItems ( ) const

pure virtual

Remarks: Returns the number of items in the menu.

virtual IMenuItem* GetItem ( int position )

pure virtual

Remarks: Returns a pointer to the specified menu item.

Parameters:: int position

The position/index in the menu.

virtual void AddItem	(	IMenuItem *	item,
