I have a collection of widgets, one is the master sitting in a
contentpane, the others are controls scattered around the page. When
the masteris destroyed I need to cleanup the controls. It is cleaner to
sit on asingle destroy event than on every possible action that could
trigger thedestroy.When I have created or inherited from existing
widgets I have overriddenthe destroy method to add a destroy event.
By the way, create isn't needed if you extend the widget either.
