57 /**
58  ** The <CODE>WindowAdapter</CODE> is a window listener in which
59  ** all callback methods are empty implementations. The window
60  ** adapter makes it more convenient for an object to listen
61  ** for window events. In particular, by using the window
62  ** adapter, it is possible to implement only those callback
63  ** methods in which you are interested. Without the window
64  ** adapter, you must implement all callback methods, even
65  ** if the method is empty.
66  **
67  ** <P>
68  ** To use the window adapter, you create a subclass of
69  ** <CODE>WindowAdapter</CODE> and override the desired callback
70  ** methods. You then create an instance of the window
71  ** adapter subclass and use it to register it as a listener
72  ** for window events.
