It should work in 5.15: see also QTBUG-79660 and the tablet manual test in 
qtdeclarative/tests/manual/pointer.

Those are currently not delivered to the main window, only to the application.

qtbase/examples/widgets/widgets/tablet/tabletapplication.cpp.  I’m hoping to 
get more complete proximity event delivery in place in Qt 6.
