I've taken a look at the QCanvas code, I haven't figured out yet how it does this... perhaps simply checking if we're scrolling and skipping some of the draw operations in that case might help. -- Guillaume. http://www.telegraph-road.org ------------------------------------------------------- SF.Net email is sponsored by: Discover Easy Linux Migration Strategies from IBM.
