A two level focus handler allows a Control to behave as if it has three focus states : - not focused - focused with internal focus - focused with external focus In external focus mode it intercepts focus and traversal events and prevents the Controls acting upon them, or trapping focus. In internal focus mode most events go to the Control, except for events that are defined to exit the mode.
