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

Question

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!

it's very LaF dependent, because the JSlider has an arrow only in Metal and, depending on current theme, GTK LaF — Denis Tulskiy, Oct 27 '10 at 05:22

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.

Thanks, that's exactly what I needed! I'm not surprised that Java won't let you do it simply for one layout element, that would be way too easy. – ahugenerd Oct 28 '10 at 12:51
