Window Events Example

For example, windows don't close on their own. You have to explicitly close them. The following subclass of Frame puts up a window that responds to efforts to close it by calling setVisible(false) and dispose().

import java.awt.*;
import java.awt.event.*;


public class ClosableFrame extends Frame implements WindowListener {

  public ClosableFrame() {
    this.addWindowListener(this);
  }
  
  public ClosableFrame(String title) {
    super(title);
    this.addWindowListener(this);
  }
  
  public void windowClosing(WindowEvent evt) {
    this.setVisible(false);
    this.dispose();
  }
  
  public void windowOpened(WindowEvent evt) {}  
  public void windowClosed(WindowEvent evt) {}
  public void windowIconified(WindowEvent evt) {}
  public void windowDeiconified(WindowEvent evt) {}
  public void windowActivated(WindowEvent evt) {}
  public void windowDeactivated(WindowEvent evt) {}

}
