      void onWeakNotify(CallbackHandler __self, @Nullable Pointer data, @Nonnull Object where_the_object_was)
      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.
      Parameter:
      data - data that was provided when the weak reference was established
      where_the_object_was - the object being disposed
