It should work in 5.15: see also QTBUG-79660 and the tablet manual test in qtdeclarative/tests/manual/pointer. > I experimented with eventFilter's to intercept QTabletEvent's before they are > converted into mouse events by the QQuickWindow (as far as I can tell).

Those are currently not delivered to the main window, only to the application. So you still need a C++ subclass in Qt 5, as in qtbase/examples/widgets/widgets/tablet/tabletapplication.cpp. I’m hoping to get more complete proximity event delivery in place in Qt 6. _______________________________________________ Interest mailing list [email protected] https://lists.qt-project.org/listinfo/interest
