Can I put a gradient background on a JSlider without creating a subClassed JSlider, and if not, how would I need to modify the JSlider to give it a gradient background (Also, both with a background file, and if possible, by just specifying the two end colors?)

you'd write a custom ui for your slider

awesome tutorial,
and that will definately be handy, but for this specific problem, I need to change only one JSlider and leave all others unchanged...

Thinking about it, It would be quite simple to create a new component and just extend paintComponent, but is there a way to add it onto an existing component without creating a new component?

u can use different ui for different instances of the same component.

That makes sense. Will try that. Thanks Objects.

ksivananth, I need something less subtle than that.

Try this AbstractComponentDecorator, which will let you decorate the background of one component at a time:

Of course, it depends on how much background the original UI leaves to be painted.

Or, you could just wrap it in a JPanel and make the JPanel paint the gradient background.

to set gradient background to panel,

    class MyPanel extends JPanel{

        public void paintComponent( Graphics g ){
            Graphics2D g2 = (Graphics2D) g;
            g2.setPaint( new GradientPaint((float)   this.getX(),(float) this.getY(), Color.BLUE, (float) this.getX(), (float) this.getY()+ this.getHeight() - 2, Color.WHITE, true));
            g2.fillRoundRect(0,0, this.getWidth(),this.getHeight(), 12, 12);
        }
    }

I feel this is a easiest one!

I agree, so I'm using it, but I think objects way is the right way to do it, and I know I'll be using that code in future, so I'm splitting points.
