abstract public class: WindowAdapter [javadoc | source] 
java.lang.Object
   java.awt.event.WindowAdapter

All Implemented Interfaces:
    WindowFocusListener, WindowListener, WindowStateListener

Direct Known Subclasses:
    Closer, WinListener, WindowHandler, Closer, FrameListener

An abstract adapter class for receiving window events. The methods in this class are empty. This class exists as convenience for creating listener objects.

Extend this class to create a WindowEvent listener and override the methods for the events of interest. (If you implement the WindowListener interface, you have to define all of the methods in it. This abstract class defines null methods for them all, so you can only have to define methods for events you care about.)

Create a listener object using the extended class and then register it with a Window using the window's addWindowListener 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 WindowEvent is passed to it.

Method from java.awt.event.WindowAdapter Detail:
 public  void windowActivated(WindowEvent e)
    Invoked when a window is activated.
 public  void windowClosed(WindowEvent e)
    Invoked when a window has been closed.
 public  void windowClosing(WindowEvent e)
    Invoked when a window is in the process of being closed. The close operation can be overridden at this point.
 public  void windowDeactivated(WindowEvent e)
    Invoked when a window is de-activated.
 public  void windowDeiconified(WindowEvent e)
    Invoked when a window is de-iconified.
 public  void windowGainedFocus(WindowEvent e)
    Invoked when the Window is set to be the focused Window, which means that the Window, or one of its subcomponents, will receive keyboard events.
 public  void windowIconified(WindowEvent e)
    Invoked when a window is iconified.
 public  void windowLostFocus(WindowEvent e)
    Invoked when the Window is no longer the focused Window, which means that keyboard events will no longer be delivered to the Window or any of its subcomponents.
 public  void windowOpened(WindowEvent e)
    Invoked when a window has been opened.
 public  void windowStateChanged(WindowEvent e)
    Invoked when a window state is changed.
