copied!<p>Why don't you hide the frame yourself instead of using a default <code>HIDE_ON_CLOSE</code>?</p> <pre><code>// inside WindowListener class public windowClosing(WindowEvent e) { yourFrame.setVisible( false ); // your code here... } </code></pre> <p>Edit made: from docs:</p> <blockquote> <p>The default close operation is executed after any window listeners handle the window-closing event. So, for example, assume that you specify that the default close operation is to dispose of a frame. You also implement a window listener that tests whether the frame is the last one visible and, if so, saves some data and exits the application. Under these conditions, when the user closes a frame, the window listener will be called first. If it does not exit the application, then the default close operation — disposing of the frame — will then be performed.</p> </blockquote> <p>New edit with a working example:</p> <pre><code>import java.awt.event.*; import javax.swing.JFrame; public class ListenerTest extends JFrame implements WindowListener { public static void main(String[] args) { ListenerTest frame = new ListenerTest(); frame.setDefaultCloseOperation(JFrame.DO_NOTHING_ON_CLOSE); frame.setVisible( true ); } public ListenerTest() { this.addWindowListener( this ); } public void windowActivated(WindowEvent e) { System.out.println(" activated "); } public void windowClosed(WindowEvent e){ System.out.println(" closed "); } public void windowClosing(WindowEvent e){ System.out.println(" closing "); } public void windowDeactivated(WindowEvent e){ System.out.println(" deactivated "); } public void windowDeiconified(WindowEvent e){ System.out.println(" deiconified "); } public void windowIconified(WindowEvent e){ System.out.println(" iconified "); } public void windowOpened(WindowEvent e){ System.out.println(" opened "); } } </code></pre> <p>Test this out in order to catch <del>what</del> which events are firing.</p>
