java.awt.event.ComponentAdapter
- All Implemented Interfaces:
- ComponentListener,- EventListener
- Direct Known Subclasses:
- BasicSliderUI.ComponentHandler,- BasicTreeUI.ComponentHandler,- JViewport.ViewListener
An abstract adapter class for receiving component events.
 The methods in this class are empty. This class exists as
 convenience for creating listener objects.
 
 Extend this class to create a ComponentEvent listener
 and override the methods for the events of interest. (If you implement the
 ComponentListener interface, you have to define all of
 the methods in it. This abstract class defines null methods for them
 all, so you can only have to define methods for events you care about.)
 
 Create a listener object using your class and then register it 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.
