yes and no,But the redraw looks fine if the window is drawn completely?
yes) if i minimize the window while its running and then bring it back up, then everything gets repainted and the image looks fine but as soon as you scroll it does the same thing.
no) it clobbers any existing information/attributes/text/colors that existed in the cell, which i want to preserve and have the image painted inside the cell as well.
i sure have, within the CustomRenderer, and when try to change/set any brush or colors or anything to $dc (which is Wx::PaintDC as you said) it crashes the program after 3-4 seconds and all that is shown is the window and a grey background without any grids or anything.Have you tried clearing the background like i wrote before:
EDIT: just had a thought, do you think it could have something to do with pixel data? as in the cell it draws, and the scroll event are two different sizes? like what if the pixel data? was smaller than the actual scrolling size of each scroll? that could cause a smearing effect could it not?
