In each pass, the pixmaps are created newly using deep copies, by QPixmap::copyRect(..), so I fear the identity is different every time(I already checked QPixmap::cacheKey()). Ah yeah, the basic pixmap they are copied from is also different every time. :) My hope was that there might be some XRender function or something like that, but I haven't found any. - David ----------------------------------------------------------- This is an automatically generated e-mail.
