Paint background of a JDialog

Question

Hey,
i have a quite simple problem: I want to paint the background of my own JDialog, but i dont know how. I looked for a method like paintComponent(Graphics g) like in a JPanel, but there is no function. So i overwrite the method paint(Graphics g) but this doesnt work because my JList and JButtons on the dialog won?t be shown anymore.
Any idea? Thanks a lot.
Ohnoooooo!

Where it is recommended to do custom painting in a BufferedImage, then draw the BufferedImage in a JPanel's paintComponent override. Then add your JList, JButtons, and whatnot to the same JPanel. And then finally add the JPanel to the contentPane of the JApplet and you should be good to go.
Many here have their GUI programs produce a JPanel as the final product. This increases flexibility quite a bit, since if the GUI is needed as a JFrame, simply add the JPanel to a JFrame, if a dialog, add the panel to a JDialog, and finally if a JApplet is needed, simply add the JPanel to the JApplet.
Good luck!
