extends java.lang.Object
implements java.awt.event.WindowListener {
// Instance Methods

public void windowClosed (WindowEvent e);
public void windowClosing (WindowEvent e);
public void windowDeactivated (WindowEvent e);
public void windowDeiconified (WindowEvent e);
public void windowIconified (WindowEvent e);
