    Description

      Is appears that QPinchGesture::startCenterPoint() is always 0,0. Also, I never see a QPinchGesture have a state of Qt::GestureStarted. Only Updated and Finished.

      Looking at the source: https://github.com/qt/qtbase/blob/dev/src/widgets/kernel/qstandardgestures.cpp - it seems startCenterPoint is only ever reset. There don't appear to be any other assignments.

      It does appear to be set in the Mac version of the gesture recognizer though: https://github.com/qt/qtbase/blob/dev/src/widgets/kernel/qmacgesturerecognizer.cpp
