java - 如何在鼠标右键单击时禁用 JSlider 的位置更改

Question

我在我的应用程序中使用了 JSlider。我只想左键单击滑动 JSlider，我想禁用 JSlider 的右键单击。我可以通过右键单击获得事件，但 slider 正在将其值更改为其他位置。

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
        }

    }
});

我使用的是 JDK1.7.0_03，Windows 7

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