I think where the item renderer is placed should be of little importance. but it is a custom list component without scroll bars but with scrolling allowed and keyboard events should not make it move/focus either, but keyboard navigation is required..... a little messy, but those were the requirements .....
I realized when working on a non-item renderer component that it had the same flickering/blinking when changing the source of the image. What I have done to combat the problem is to have 2 images in my item renderer plus a flag that tells which image should be upgraded next. In essence a similar technique as one would use to hide the raster line on real-time graphics systems. Update one screen while showing the other .... and vice versa! --Allan On Nov 27, 2007 9:26 AM, Alex Harui <[EMAIL PROTECTED]> wrote: > > > > > We would need to see a test case.
