/**
 ** The <CODE>WindowAdapter</CODE> is a window listener in which
 ** all callback methods are empty implementations. The window
 ** adapter makes it more convenient for an object to listen
 ** for window events. In particular, by using the window
 ** adapter, it is possible to implement only those callback
 ** methods in which you are interested. Without the window
 ** adapter, you must implement all callback methods, even
 ** if the method is empty.
 **
 ** <P>
 ** To use the window adapter, you create a subclass of
 ** <CODE>WindowAdapter</CODE> and override the desired callback
 ** methods. You then create an instance of the window
 ** adapter subclass and use it to register it as a listener
 ** for window events.
