public class StickyImageButtonController
extends ImageButtonController
An ImageButtonController that causes its associated ImageButton to "stick" when activated. If the ImageButton is raised it depresses[1] upon a mouse down and stays down upon a subsequent mouse up event. The same "sticky" behaviour occurs when a depressed ImageButton encounters a mouse down followed by a subsequent mouse up.

Note that false is returned from mouse event handlers; therefore mouse events will be propagated to the ImageButton's container. While this is not always desirable, it was deemed a better default than swallowing the event here. Subclasses may, of course, modify this behavior.
