void g_menu_model_items_changed ( GMenuModel* model, gint position, gint removed, gint added )
Requests emission of the
GMenuModel::items-changed signal on
This function should never be called except by
subclasses. Any other calls to this function will very likely lead
to a violation of the interface of the model.
The implementation should update its internal representation of the menu before emitting the signal. The implementation should further expect to receive queries about the new state of the menu (and particularly added menu items) while signal handlers are running.
The implementation must dispatch this call directly from a mainloop
entry and not in response to calls — particularly those from the
GMenuModel API. Said another way: the menu must not change while
user code is running without returning to the mainloop.
