the item factory features two different types of callback_data, this is
the callback signature:

static void
factory_callback (gpointer             callback_data,
                  guint                callback_action,
                  GtkWidget           *widget);

here, `callback_data' is the `callback_data' pointer that you passed into
gtk_item_factory_create_items() or gtk_item_factory_create_item().
`callback_action' is the value of GtkItemFactoryEntry.callback_action, thus
it's always menu item specific. `widget' is a pointer to the menu item that
got selected, and the factory itself can be retrived back from this widget
via gtk_item_factory_from_widget().
