were you using Qt's built-in image handlers, or were you using your own image handler? the reason i ask is that Qt's built-in image handlers are known to be slow and inefficient. there is work to improve that, but it isn't optimized for large image handling right now ... i'm guessing you just used the default showimg app as-is... in any case, there is probably no reason why you can't take your Xlib implementation and wrap it in a QWidget subclass and get the best of all worlds. after all, that's what all QWidgets do at the lowest level: use raw X calls via QPainter to draw things. btw, i do Qt consulting if anyone's interested ;-) wow. now THERE'S a shameless plug if i ever saw one. - -- Aaron J.
