Is there a way to flip a JSlider so that the slider arrow points upwards?

I've been trying to find a way to do this for a while now and can't quite seem to figure it out. I know you can change the orientation of a JSlider, using setOrientation(HORIZONTAL|VERTICAL), and that you can also invert the scale, using setInverted(true). My problem is as follows:

1) The JSlider needs to be horizontal;
2) The JSlider needs to be below the data;
3) The arrow (pointy-tip) on the actual slider should be pointing upwards, not downwards (i.e.: towards the data).

The only way I can fathom to do this is to overwrite the paintComponent method from JComponent and entirely re-code it for a custom JSlider, which seems a tad ridiculous, and I'm not even sure it would work.

Thanks for the help!

Solution

  • You can override the thumbnail used in UIManager How to hide the knob of jSlider?

    UIManager.getLookAndFeelDefaults().put(
    "Slider.horizontalThumbIcon",
    new Icon('your_icon')
);

    However, this would be done to all sliders in your program.
