First of all, upgrade to at the very least 4.8.7. Second, schedule a port to Qt 5. Third, like Jason said, the way to improve performance with stylesheets is to make them smaller. Not by removing spaces, but by removing selectors. Use stylesheets as little as you can. They're meant for final touches in UIs, not for designing UIs. -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel Open Source Technology Center _______________________________________________ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
