public interface ComponentListener extends EventListener
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.
