Override JTree listener?

37
Hello everyone!
I'm stuck with a problem, caused by a mix of listeners in a JTree.

Here goes:
I created my own renderer for the tree, that is one JLabel (icon+name), and then another JLabel (let's name it button) that has a small icon. I want the user to be able to click on the "button" JLabel and something to happen.

e.g.
Program1 (on)
Program2 (on)

assuming (on) is an icon. When the user presses (on) i want the icon to turn into (off) and turn off Program1.
as shown in this image:



Here is the code:
Expand|Select|Wrap|Line Numbers
  1.  public TreeRenderer()  {
  2.     renderer = new JPanel(new GridLayout(0, 1));
  3.     renderer.setLayout(new BoxLayout(renderer, BoxLayout.X_AXIS));
  4.     titleLabel = new JLabel(" ");
  5.     titleLabel.setForeground(Color.black);
  6.     renderer.add(titleLabel);
  7.     buttonLabel = new JLabel(" ");
  8.     buttonLabel.addMouseListener(new java.awt.event.MouseAdapter() {
  9.             private boolean on;
  10.  
  11.             @Override
  12.             public void mouseClicked(java.awt.event.MouseEvent evt) {
  13.                 System.out.println("shalal");
  14.                                 System.out.println(" clicked ");
  15.                 on=true;
  16.                 icon = createImageIcon("http://bytes.com/images/jtree red.jpg","");
  17.                 buttonLabel.setIcon(icon);
  18.             }
  19.             @Override
  20.             public void mouseEntered(java.awt.event.MouseEvent evt) {
  21.                 System.out.println("sda");
  22.             }
  23.             @Override
  24.             public void mouseExited(java.awt.event.MouseEvent evt) {
  25.                 System.out.println("14");
  26.             }
  27.         });
  28.  
  29.     renderer.add(buttonLabel);
However, when I click on the "button" nothing happens. Does anyone have any idea?
Thanks in advance!
