When To Use
The IItemDef interface is used to define a command item that's on a toolbar or menu. This interface specifies the identifier (CLSID or ProgID) of the command and its subtype if there is one. It also determines whether this item begins a group on the toolbar or menu. Use the IItemDef interface with the GetItemInfo method on either the IToolbarDef or the IMenuDef interface to define the items on the toolbar or menu.
