Hi, I installed the Qt 5 beta 1 yesterday for the first time and started porting my application (a small "visual effects editor" consisting of a couple of libraries and executable - so nothing big).
The effor was indeed very painless: in my case I mainly had to adjust a few #include (<QtGui/Whatever> -> <QtWidgets/Whatever>) and change QDir::convertSeparators to QDir::toNativeSeparators. After solving another glitch (add 'widgets' to QT configuration!) I was ready to go, everything compiled and linked! GOOD: - "Lion Fullscreen" is now supported out of the box (so I can get rid of my native API hacking :)) However it seems that the "fullscreen" option is added to every main window by default. Not sure whether I really want this (should be a window configuration flag maybe - or maybe that's already present as an option?) - Scrollbars behave as epected on (Mountain) Lion! They disappear and re-appear when hovering with the mouse over it - All my application logic still seems to work (showing dialogs, shortcuts, ...) :) BAD: - It seems that touch events are not recognised anymore by my QGraphicsSceneView - Lots of rendering artifacts (mostly seems like a "refresh" problem: old pixel "blocks" remain on the screen until a repaint is enforced, e.g. by rescaling the window - can also be observed with the Qt 5 Designer etc.) - setUnifiedTitleAndToolBarOnMac(true) doesn't seem to have an effect anymore: THIS IS AN ABSOLUTE SHOW-STOPPER ON MAC! I also tried in combination with QApplication::setGraphicsSystem("native"), but I guess the later has become a "placebo API" anyway - Further little quirks, e.g. it happened that the main window suddenly disappeared when the sheet dialog "Save before quit" should have appeared. But I need to investigate in more detail on these issues. - The QEvent::ActivationChange event doesn't seem to be propagated to my main window (at least not in the same way it did as on Qt 4.8) when my application first shows the main window - only when I do a resize of the window I get the activation change event. _______________________________________________ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
