Interface WindowStateListener

  • All Superinterfaces:
    All Known Implementing Classes:
    AWTEventMulticaster, BasicToolBarUI.FrameListener, JMenu.WinListener, WindowAdapter

    public interface WindowStateListener
    extends EventListener
    The listener interface for receiving window state events.

    The class that is interested in processing a window state event either implements this interface (and all the methods it contains) or extends the abstract WindowAdapter class (overriding only the methods of interest).

    The listener object created from that class is then registered with a window using the Window's addWindowStateListener method. When the window's state changes by virtue of being iconified, maximized etc., the windowStateChanged method in the listener object is invoked, and the WindowEvent is passed to it.
