In this case it should be written differently: just add a callback to
delete the swallowed object and that's it, no need to get the
swallowed part from the edje itself, something like:
do_add(...) {
my_object_storage->swallowed_parts = NULL;
evas_object_smart_callback_add(o, cb_swallow_free, my_object_storage);
}
do_swallow(...) {
edje_object_part_swallow(edje, part, object);
my_object_storage->swallowed_parts =
evas_list_append(my_object_storage->swallowed_parts, object);
}
do_unswallow(...) {
edje_object_part_unswallow(edje, object);
my_object_storage->swallowed_parts =
evas_list_remove(my_object_storage->swallowed_parts, object);
}
cb_swallow_free(...) {
for (l = my_object_storage->swallowed_parts; l != NULL; l = l->next)
evas_object_del(l->data);
}
If my_object_storage will be freed before cb_swallow_free() is called,
you can always malloc() the pointer to Evas_List* and use it, just
remember to free it in cb_swallow_free().
