Interface ComponentListener
- All Superinterfaces:
- EventListener
- All Known Implementing Classes:
- AWTEventMulticaster,- BasicInternalFrameUI.ComponentHandler,- BasicSliderUI.ComponentHandler,- BasicTreeUI.ComponentHandler,- Component.AccessibleAWTComponent.AccessibleAWTComponentHandler,- ComponentAdapter,- JViewport.ViewListener
The listener interface for receiving component events.
 The class that is interested in processing a component event
 either implements this interface (and all the methods it
 contains) or extends the abstract 
ComponentAdapter class
 (overriding only the methods of interest).
 The listener object created from that class is then registered with a
 component using the component's addComponentListener
 method. When the component's size, location, or visibility
 changes, the relevant method in the listener object is invoked,
 and the ComponentEvent is passed to it.
 
 Component events are provided for notification purposes ONLY;
 The AWT will automatically handle component moves and resizes
 internally so that GUI layout works properly regardless of
 whether a program registers a ComponentListener or not.
