custom JSlider

[spidermo]

I am wondering if it is possible to change the shape/size of the track and the knob of a JSlider. All I can find out how to do is add tick marks, labels, and make it longer. I am just wondering how to change the track display and the knobs display.
I am not sure as to how to go about writing my own JSlider class.
I have looked around quite a bit and have not found help.
Thanks if you have any suggestions.

I'm not a Java GUI expert, so you might want to double-check what I'm about to say.

My impression is that no, there isn't a trivial way to change the look/feel of JSlider because you're using a look/feel theme that's suppose to convey uniformity across the application. If you want to change the way the individual components render, you need to use/develop a different look/feel and apply it to the whole application.

Yeah, that makes sense. Meanwhile, I have started to make my own simple replica jslider. It will work for what I am doing, but I think I will look into making a look and feel. But from what I have seen, it is a lot of work...
Thanks for your thoughts.

I have found a solution. What I did is subclass BasicSliderUI() and override the getThumbSize() and the calculateTrackRect() methods. And then of course I applied it to the JSlider with setUI(SliderUI).

Good hack. Keep it in mind if I ever program a GUI in Java again.
