Safely destroys the #ClutterActor currently pointer to by the iterator from its parent.
This function can only be called after clutter_actor_iter_next() or clutter_actor_iter_prev() returned %TRUE, and cannot be called more than once for the same actor.
This function will call clutter_actor_destroy() internally.
Initializes a #ClutterActorIter, which can then be used to iterate
efficiently over a section of the scene graph, and associates it
with root.
Modifying the scene graph section that contains root will invalidate
the iterator.
ClutterActorIter iter;
ClutterActor *child;
clutter_actor_iter_init (&iter, container);
while (clutter_actor_iter_next (&iter, &child))
{
// do something with child
}
Checks whether a #ClutterActorIter is still valid.
An iterator is considered valid if it has been initialized, and if the #ClutterActor that it refers to hasn't been modified after the initialization.
Advances the iter and retrieves the next child of the root #ClutterActor
that was used to initialize the #ClutterActorIterator.
If the iterator can advance, this function returns %TRUE and sets the
child argument.
If the iterator cannot advance, this function returns %FALSE, and
the contents of child are undefined.
Advances the iter and retrieves the previous child of the root
#ClutterActor that was used to initialize the #ClutterActorIterator.
If the iterator can advance, this function returns %TRUE and sets the
child argument.
If the iterator cannot advance, this function returns %FALSE, and
the contents of child are undefined.
Safely removes the #ClutterActor currently pointer to by the iterator from its parent.
This function can only be called after clutter_actor_iter_next() or clutter_actor_iter_prev() returned %TRUE, and cannot be called more than once for the same actor.
This function will call clutter_actor_remove_child() internally.
An iterator structure that allows to efficiently iterate over a section of the scene graph.
The contents of the #ClutterActorIter structure are private and should only be accessed using the provided API.
