31 * The listener interface for receiving window state events.
32 * <p>
33 * The class that is interested in processing a window state event
34 * either implements this interface (and all the methods it contains)
35 * or extends the abstract <code>WindowAdapter</code> class
36 * (overriding only the methods of interest).
37 * <p>
38 * The listener object created from that class is then registered with
39 * a window using the <code>Window</code>'s
40 * <code>addWindowStateListener</code> method. When the window's
41 * state changes by virtue of being iconified, maximized etc., the
42 * <code>windowStateChanged</code> method in the listener object is
43 * invoked, and the <code>WindowEvent</code> is passed to it.
