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.<P><DL><DT><B>Since: </B><DD>1.1</DD><DT><B>See Also: </B><DD><A HREF="../../../java/awt/event/WindowAdapter.html"><CODE>WindowAdapter</CODE></A>, <A
