A little progress, by sending the TouchEvents to viewport QGLWidget the gesture recognizer is recognizing the tap gesture. However, the tap gesture fails with this message:
QGestureManager::deliverEvent: could not find the target for gesture 1
Like the touch events, gesture manager invokes topLevelAt which returns a window ID (1001) which can’t be found in the list of QWidgets (mapper).
topLevelAt is finding the points, but the window ID used by windowAt isn’t being found.
