| /** |
| * The listener interface for receiving window events. |
| * The class that is interested in processing a window event |
| * either implements this interface (and all the methods it |
| * contains) or extends the abstract <code>WindowAdapter</code> class |
| * (overriding only the methods of interest). |
| * The listener object created from that class is then registered with a |
| * Window using the window's <code>addWindowListener</code> |
| * method. When the window's status changes by virtue of being opened, |
| * closed, activated or deactivated, iconified or deiconified, |
| * the relevant method in the listener object is invoked, and the |
| * <code>WindowEvent</code> is passed to it. |
