A swing/awt component that looks like a LED

[=?iso-8859-1?q?J=FCrgen_Gerstacker?=]

Hi,
I want to create LED (light emitting diodes) inside a panel, or
rectangulars that can be given any color at any time. What is the best
solution? java.awt.Canvas?

If using AWT (without Swing):
extend Canvas, override method paint(Graphics).
If using Swing:
extend JComponent, override method paintComponent(Graphics).

A few minutes after I had posted I found a solution, that's the reason
I deleted the original post.

pan_swi=new JPanel();
pan_swi.setPreferredSize(dim1);
pan_swi.setBackground(Color.black);
....
pan_swi.setBackground(Color.red);

Thank you for your solutions, I will try them
