    fa.setBounds(100, 100, 400, 200); 
    fa.setVisible(true); 
    fa.addWindowListener(new WindowListener() { 

     @Override 
     public void windowOpened(WindowEvent e) { 
      JOptionPane.showMessageDialog(fa, "windowOpened"); 
     } 

     @Override 
     public void windowClosing(WindowEvent e) { 
      JOptionPane.showMessageDialog(fa, "windowClosing"); 
     } 

     @Override 
     public void windowClosed(WindowEvent e) { 
      JOptionPane.showMessageDialog(fa, "windowClosed"); 
     } 

     @Override 
     public void windowIconified(WindowEvent e) { 
      JOptionPane.showMessageDialog(fa, "windowIconified"); 
     } 

     @Override 
     public void windowDeiconified(WindowEvent e) { 
      JOptionPane.showMessageDialog(fa, "windowDeiconified"); 
     } 

     @Override 
     public void windowActivated(WindowEvent e) { 
     //    JOptionPane.showMessageDialog(fa, "windowActivated"); 
     } 

     @Override 
     public void windowDeactivated(WindowEvent e) { 
     //    JOptionPane.showMessageDialog(fa, "windowDeactivated"); 
     } 
    });
