The QHoverEvent ctor takes two points: scenePos and globalPos; the first of those is passed to the QSinglePointEvent ctor as _both_ the local and scene pos, which calls QMutableEventPoint::setScenePosition() on the persistent QEventPoint instance, and then detaches before setting ephemeral state. Therefore, we must construct QHoverEvent with scene position, not local position, so that the right value is persisted. To localize a QHoverEvent during delivery, use QMutableEventPoint::setPosition(). This needs to be done repeatedly while visiting multiple widgets or items; the detach() prevents it from being saved in the persistent QEventPoint in QPointingDevicePrivate::EventPointMap.
