Hi Hans,

I see you are creating a "JLabel" and then adding the Meter object into it.

Why don't you just "paint" the SpeedMeter with the image you need in the background and just add "SpeedMeter" in the JPanel?

- Set up the background image in the SpeedMeter paintComponent() (once it's a JLabel).
- Don't forget to use the repaint() method if you need to update the "Meters"
- Once you have done that, just instantiate a SpeedMeter and add it to the panel object.

Does it make sense?

I agree. Here's the link:
