Window Events

Since java.awt.Window is a subclass of java.awt.Component, a Window, Frame or Dialog can fire events. In particular it fires WindowEvents. There are seven of these:


	WindowEvent.WINDOW_ACTIVATED 
	
WindowEvent.WINDOW_CLOSED 
	
WindowEvent.WINDOW_CLOSING 
	
WindowEvent.WINDOW_DEACTIVATED 
	
WindowEvent.WINDOW_DEICONIFIED 
	
WindowEvent.WINDOW_ICONIFIED 
	
WindowEvent.WINDOW_OPENED

To respond to these events you register a WindowListener object with the window. The object must implement the WindowListener interface and include these methods:

  public abstract void windowOpened(WindowEvent e)
  public abstract void windowClosing(WindowEvent e)
  public abstract void windowClosed(WindowEvent e)
  public abstract void windowIconified(WindowEvent e)
  public abstract void windowDeiconified(WindowEvent e)
  public abstract void windowActivated(WindowEvent e)
  public abstract void windowDeactivated(WindowEvent e)
