Perhaps the documentation shouldn't construct it on the stack if that's not how it's meant to be used: http://doc-snapshot.qt-project.org/qt5-stable/animation-overview.html#animating-qt-properties I can see that the person writing that example probably did it in main(), but that's not how most people will be using it. Should I submit a patch? _______________________________________________ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
