+/**
+ * The listener interface for receiving <code>WindowEvents</code>, including
+ * <code>WINDOW_GAINED_FOCUS</code> and <code>WINDOW_LOST_FOCUS</code> events.
+ * The class that is interested in processing a <code>WindowEvent</code>
+ * 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
+ * <code>Window</code>
+ * using the <code>Window</code>'s <code>addWindowFocusListener</code> method.
+ * When the <code>Window</code>'s
+ * status changes by virtue of it being opened, closed, activated, deactivated,
+ * iconified, or deiconified, or by focus being transfered into or out of the
+ * <code>Window</code>, the relevant method in the listener object is invoked,
+ * and the <code>WindowEvent</code> is passed to it.
