    demo.makeFrame();
    demo.frame.addWindowListener(new WindowAdapter() {
        public void windowClosing(WindowEvent e) {
            System.exit(0);
        }
    });
    demo.frame.show();
}


public JFrame makeFrame() {
    frame = new JFrame();
    // Create a horizontal split pane.
    pane = new JSplitPane(JSplitPane.HORIZONTAL_SPLIT);
    left = new JPanel();
    left.setBackground(Color.red);
    pane.setLeftComponent(left);
    right = new JPanel();
    right.setBackground(Color.green);
    pane.setRightComponent(right);

    JButton showleft = new JButton("Left");
    showleft.addActionListener(new ActionListener() {
        public void actionPerformed(ActionEvent e) {
            Container c = frame.getContentPane();
            if (pane.isShowing()) {
                lastDividerLocation = pane.getDividerLocation();
            }
            c.remove(pane);
            c.remove(left);
            c.remove(right);

                lastDividerLocation = pane.getDividerLocation();
            }
            c.remove(pane);
            c.remove(left);
            c.remove(right);
            c.add(right, BorderLayout.CENTER);
            c.validate();
            c.repaint();
        }
    });
    JButton showboth = new JButton("Both");
    showboth.addActionListener(new ActionListener() {
        public void actionPerformed(ActionEvent e) {
            Container c = frame.getContentPane();
            c.remove(pane);
            c.remove(left);
            c.remove(right);
            pane.setLeftComponent(left);
            pane.setRightComponent(right);
            c.add(pane, BorderLayout.CENTER);
            if (lastDividerLocation >= 0) {
                pane.setDividerLocation(lastDividerLocation);
            }
            c.validate();
            c.repaint();
        }
    });

    JPanel buttons = new JPanel();
    buttons.setLayout(new GridBagLayout());
    buttons.add(showleft);
    buttons.add(showright);
    buttons.add(showboth);
    frame.getContentPane().add(buttons, BorderLayout.NORTH);

    pane.setPreferredSize(new Dimension(400, 300));
    frame.getContentPane().add(pane, BorderLayout.CENTER);
    frame.pack();
    pane.setDividerLocation(0.5);
    return frame;
}
