Canvas -> Swing, paintComponent() not working

[NeedMiscHelp]

Everyone says to use JComponent or JPanel instead of Canvas. I override paintComponent() with the code that was formerly in paint(), but nothing shows up. I just get a gray panel. I put in a System.out.println() statement in the paintComponent() method and make sure it only prints out at the most 5 times (based on a global variable). I see that nothing even gets printed??!! Then my computer crashes... soooo what else am I supposed to besides simply override paintComponent()?

You may need to turn any layout managers you have on off.

I'm not sure if this will help, but last time I got paintComponent to work I have the line

setLayout(null)

in my constructor.

Lets us know how it goes. ----------------------------------------

I found the solution to my problem- the Canvas used to be in a JPanel itself, now I was adding a JPanel to a JPanel to a JScrollPane. So now I just directly add the first JPanel to JScrollPane. Alternatively, I think one could use setOpaque(false) on the container JPanel if more stuff needed to be added. That layout tip kind of help.
