  38  * <P>
  39  * Create a listener object using the extended class and then register it with
  40  * a Window using the window's <code>addWindowListener</code>
  41  * method. When the window's status changes by virtue of being opened,
  42  * closed, activated or deactivated, iconified or deiconified,
  43  * the relevant method in the listener
  44  * object is invoked, and the <code>WindowEvent</code> is passed to it.
