title: System tray icon, add a "click here" link
body: <p>I have the following code to open a window notification but I want the part that says "click here" to link to a text file. How do I add this function into the trayicon?</p>
  
  <pre><code>public class foundDocs implements ActionListener {
  
  
  public static void main(String[]args) throws AWTException
  {
      new foundDocs();
  }
  foundDocs() throws AWTException 
     { 
         SystemTray tray = SystemTray.getSystemTray(); 
          java.awt.Image image = Toolkit.getDefaultToolkit().getImage("tray.gif"); 
          TrayIcon trayIcon = new TrayIcon(image, "Tray Demo"); 
          tray.add(trayIcon); 
          trayIcon.displayMessage("Found new document associations:", "Click here to view", MessageType.INFO); 
          trayIcon.addActionListener(this);
      }
  
  @Override
  public void actionPerformed(ActionEvent arg0) 
  {
      // display the text file in the default app. 
      try {
          Desktop.getDesktop().open(new File("Users.txt"));
      } catch (IOException e) {
          // TODO Auto-generated catch block
          e.printStackTrace();
      } 
  
  }
  </code></pre>
  
  <p>}</p>
