/* This is the GtkItemFactoryEntry structure used to generate new menus.

                accelerator key once the menu is open.
        Item 2: The accelerator key for the entry
        Item 3: The callback function.

                which the function is called.  The default is 0.
        Item 5: The item type, used to define what kind of an item it is.
