WeakNotify

A #GWeakNotify function can be added to an object as a callback that gets triggered when the object is finalized.

Since the object is already being disposed when the #GWeakNotify is called, there's not much you could do with the object, apart from e.g. using its address as hash-index or the like.

In particular, this means it’s invalid to call g_object_ref(), g_weak_ref_init(), g_weak_ref_set(), g_object_add_toggle_ref(), g_object_weak_ref(), g_object_add_weak_pointer() or any function which calls them on the object from this callback.
