I am implementing a pan and zoom on pinch via raw touch events and am finding setTransform() to be very slow, even with an empty scene. The touch events are backed up in a queue by slow synchronous calls to QGraphicsView.setTransform().
Without stripping down my code into a runnable example, is setTransform considered to be too slow for 60Hz frame-rate updates from touch events? If so, is there a better way to smoothly zoom and pan the graphics view? Thanks! -P _______________________________________________ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
