How to disable position change of JSlider on mouse right click


I am using a JSlider in my application. I want only left click to slide JSlider, and I want to disable right click for JSlider. I am able to get event on right click, but slider is changing its value to other position.

jSlider.addChangeListener(new ChangeListener() {

    public void stateChanged(ChangeEvent e) {
        //code
    }
});

jSlider.addMouseListener(new MouseAdapter() {

    public void mouseReleased(MouseEvent e) {

        if (e.getButton() == java.awt.event.MouseEvent.BUTTON3) {
            //code
        } else {
            //code
        }

    }
});

Solution

  • I am using JDK1.7.0_03, Windows 7

    UIManager.put("Slider.onlyLeftMouseButtonDrag", Boolean.TRUE);
    

    JDK1.6.0_31:
