"If it needs one". The details depend on implementation details of the rendering and event delivery architecture, and should be irrelevant to everything but that code. They are also subject to change without notice, and I can guarantee that such changes will happen. Put another way, why exactly do you need to know? I can't think of circumstances where you'd really want to know whether a given frame has a view or a given view has a widget.... -Boris
