title: AWT Window Close Listener/Event
body: <p>I am sorry if this is a n00b question, but I have spent <em>way</em> too long for this once I create the Window listener, window event, and everything else, how do I specify what method to invoke? Here is my code:</p>
  
  <pre><code>private static void mw() {
      Frame frm = new Frame("Hello Java");
      WindowEvent we = new WindowEvent(frm, WindowEvent.WINDOW_CLOSED);
      WindowListener wl = null;
      wl.windowClosed(we);
      frm.addWindowListener(wl);
      TextField tf = new TextField(80);
      frm.add(tf);
      frm.pack();
      frm.setVisible(true);
  
  }
  </code></pre>
  
  <p>I am trying to get a URL, and Download it, I have everything else worked out, I am just trying to get the window to close.</p>
