31 31 * The listener interface for receiving <code>WindowEvents</code>, including
32 32 * <code>WINDOW_GAINED_FOCUS</code> and <code>WINDOW_LOST_FOCUS</code> events.
33 33 * The class that is interested in processing a <code>WindowEvent</code>
34 34 * either implements this interface (and
35 35 * all the methods it contains) or extends the abstract
36 36 * <code>WindowAdapter</code> class (overriding only the methods of interest).
37 37 * The listener object created from that class is then registered with a
38 38 * <code>Window</code>
39 39 * using the <code>Window</code>'s <code>addWindowFocusListener</code> method.
