title: JWebBrowser (extends JPanel) Showing Above Glass Pane
body: <p>I am using the DJ Native Swing API to be able to use JWebBrowser.</p>
  
  <pre><code>public class GUI extends JPanel {
  
      Robot robot;
      JComponent glassPane;
  
      public GUI(final Bot bot) {
          super(new BorderLayout());
          try {
              robot = new Robot();
          } catch (AWTException e) {
              e.printStackTrace();
          }
          JPanel webBrowserPanel = new JPanel(new BorderLayout());
          JWebBrowser webBrowser = new JWebBrowser(JWebBrowser.constrainVisibility());
          webBrowser.setBarsVisible(false);
          webBrowser.setButtonBarVisible(false);
          webBrowser.setMenuBarVisible(false);
          webBrowser.navigate("http://google.com");
          webBrowserPanel.add(webBrowser, BorderLayout.CENTER);
          add(webBrowserPanel, BorderLayout.CENTER);
  
          JPanel buttonPanel = new JPanel(new FlowLayout(FlowLayout.CENTER, 4, 4));
          final JButton button = new JButton("Start");
          button.addActionListener(new ActionListener() {
              @Override
              public void actionPerformed(ActionEvent e) {
                  if (bot.isRunning()) {
                      button.setText("Start");
                  } else {
                      button.setText("Stop");
                  }
                  bot.setRunning(!bot.isRunning());
              }
          });
          buttonPanel.add(button, BorderLayout.WEST);
          add(buttonPanel, BorderLayout.NORTH);
  
          JFrame mainFrame = new JFrame("Bot");
          mainFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
          mainFrame.getContentPane().add(this, BorderLayout.CENTER);
  
          glassPane = new JComponent()
          {
              public void paintComponent(Graphics g)
              {
                  g.setColor(new Color(1, 0, 0, 0.5f));
                  g.fillRect(10, 10, 815, 775);
              }
          };
          glassPane.setSize(815,775);
          glassPane.setOpaque(false);
         mainFrame.setGlassPane(glassPane);
          glassPane.setVisible(true);
  
  
          mainFrame.setSize(815, 775);
          mainFrame.setLocationRelativeTo(null);
          mainFrame.setVisible(true);

  <p>When I run this, I expect to see a red rectangle over the whole GUI. This is not what happens. This is what I see (sorry, it won't let me post direct images):

  <p>Why is the JWebBrowser appearing over the glass pane? I thought the Glass Pane should be over EVERYTHING.</p>
  
  <p>JWebBrowser extends JPanel. Here is the documentation: <a href="http://djproject.sourceforge.net/ns/documentation/javadoc/chrriis/dj/nativeswing/swtimpl/components/JWebBrowser.html" rel="nofollow">Javadoc</a></p>
  
  <p>My goal for this glass pane is to be able to get the mouse position when the user is using the GUI. For some reason the mouse position is returning null (even though it is over the component) using webBrowser.getMousePosition() or webBrowserPanel.getMousePosition().</p>
