Is there a way to update only a portion of the screen instead of repainting the whole screen? I have a screen with many graphics and I have a bit of animation. Basically a small graphic moving around the screen.

I'm using UiApplication.getUiApplication().repaint(), but this seems to repaint the whole screen. Can I just repaint a section?

Toughie -- This is something I would like to know about since I'm very interested in writing a simple purpose-designed telnet app designed for Canadian relay service, or helping a company make one.

All the J2ME code I've looked at use some kind of a repaint( ) method.

There has got to be a way... maybe Blackberry specific way. The information might be found in a search on RIM's developer forum.

Good news!

I found the information: Partial Repaints

The basic idea is you set a clip region ( rectangular ) and whenever you call repaint it will only re-draw the pixels in that clip region.
