## java.awt.event
Interface WindowStateListener

All Superinterfaces:
  EventListener

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.

Since:
  1.4
See Also:
  `WindowAdapter`, `WindowEvent`

Method Summary
`void` | `windowStateChanged(WindowEvent e)` Invoked when window state is changed.

Method Detail

### windowStateChanged
