Usage

From source file:Main.java

public static void main(String[] args) {
    Color TRUE_COLOR = new Color(180, 200, 255);
    Color FALSE_COLOR = new Color(255, 100, 100);

    final MyBean panel = new MyBean();
    panel.setTitle(true);/*from  w  w  w. j a  va2  s .  co m*/
    panel.setBackground(TRUE_COLOR);
    panel.addMouseListener(new MouseAdapter() {
        @Override
        public void mousePressed(MouseEvent e) {
            panel.setTitle(!panel.getTitle());
        }
    });
    panel.addPropertyChangeListener(new PropertyChangeListener() {

        @Override
        public void propertyChange(PropertyChangeEvent evt) {
            if (evt.getPropertyName().equals(MyBean.TITLE_PROP_NAME)) {
                panel.setBackground(panel.getTitle() ? TRUE_COLOR : FALSE_COLOR);
            }
        }
    });
    JFrame frame = new JFrame();
    frame.getContentPane().add(panel);
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.setSize(400, 300);

    frame.setVisible(true);
