推荐答案

JFrame frame = new JFrame();
final JPanel origPanel = new JPanel();
frame.add(origPanel, BorderLayout.CENTER);

MouseListener ml = new MouseAdapter() {
  public void mouseClicked(MouseEvent evt) {
    // Mouse clicked on panel so remove existing panel and add a new one.
    frame.remove(origPanel);
    frame.add(createNewPanel(), BorderLayout.CENTER);

    // Revalidate frame to cause it to layout the new panel correctly.
    frame.revalidate();

    // Stop listening to origPanel (prevent dangling reference).
    origPanel.removeMouseListener(this);
  }
}

origPanel.addMouseListener(ml);
