That paint engine was always experimental and the experiment concluded. There were two important conclusions: a) retrofitting paint events on top of OpenGL is hard and not efficient, plus it was not pixel-perfect b) proper OpenGL integration requires a stack designed with OpenGL in mind The result of (b) is a retained-mode scene graph. It's in the QtQuick library. > From my experience with the QSkinny project I'm tempted to say that it > would even be possible to implement the Qt/Widgets API on top of Qt/Quick > core. So long as you ditch the paint event for most of the classes, leaving the QQuickPaintedItem (or whatever it's called) only for the cases where it's truly needed. -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel Open Source Technology Center _______________________________________________ Development mailing list Development@qt-project.org http://lists.qt-project.org/mailman/listinfo/development
