Howdy !

Whats the better place to do all the paintingstuff,
in the update(g) or in the paint(g), regarding performance.
As far as i know a repaint calls the update(g), then the update should call paint(g), so is there any reason not to do the painting in the update(g) ?

Its been awhile since I did this AWT stuff but i believe you will find that Update(0 does a lot of other stuff, including painting the background and handling some of the complex coordination needed for swing.
I woulf *not* override update but instead override paint.
YMMV.

If the base window is derived from Swing classes, maybe even better override paintComponent()?

Jeff, do you mean that for using Swing-Components or, too, for painting game-content without any of the awt-Components (like Panel etc.) included ?

If you're using older style AWT type graphics, then override update to avoid flickering.

If you are using Swing classes, then don't touch update ( I think it's not even called anymore) and override either paint() or paintComponent().

paintComponent() is good to override because then component borders will be painted properly.

What is the better way  ? Using Swing-classes or using awt ?

That depends on your usage, but usually Swing is preferred.  It is certainly a more modern API.
