Here's how I would do it. Its by no means the only way, so
if anybody has something to add/subtract from this, feel free.
Anyway, I wouldn't mess with the JSlider. Instead, the way
I would do it is something like this:
public class SteeringWheel extends JPanel {
AffineTransform currentRotation=new AffineTranform().;
ImageIcon wheelImage=new ImageIcon("wheel.gif");
public int getRotationDegrees() {
// may need to dust off the old trig book for this one ;)
}
public void paint(Graphics g) {
Graphics2D g2d=(Graphics2D)g;
g2d.drawImage(wheelImage,currentRotation,this);
}
};
Then just have that guy either implement a MouseListener or MouseAdapter,
(whichever you prefer) and those functions should call
currentRotation.rotate(theta);
when the component is "dragged".
I hope this helps,
-KC

Subject: Rounded JSlider.
Hello,
I need to build something similar to a JSlider but rounded (to represent
a wheel that drives a car). Anybody have some idea about how can I do
that? (some orientation would be greatly appreciated).
Thanks a lot
