  31  * The listener interface for receiving component events.

  33  * either implements this interface (and all the methods it
  34  * contains) or extends the abstract <code>ComponentAdapter</code> class
  35  * (overriding only the methods of interest).
  36  * The listener object created from that class is then registered with a
  37  * component using the component's <code>addComponentListener</code>
  38  * method. When the component's size, location, or visibility
  39  * changes, the relevant method in the listener object is invoked,
  40  * and the <code>ComponentEvent</code> is passed to it.
  41  * <P>
  42  * Component events are provided for notification purposes ONLY;
  43  * The AWT will automatically handle component moves and resizes
  44  * internally so that GUI layout works properly regardless of
  45  * whether a program registers a <code>ComponentListener</code> or not.
