point eventPoint.globalGrabPosition: see also QEventPoint::globalGrabPosition
point eventPoint.globalLastPosition: see also QEventPoint::globalLastPosition
point eventPoint.globalPosition: see also QEventPoint::globalPosition
point eventPoint.globalPressPosition: see also QEventPoint::globalPressPosition
bool eventPoint.grabPosition: see also QEventPoint::grabPosition
int eventPoint.id: see also QEventPoint::id
point eventPoint.lastPosition: see also QEventPoint::lastPosition
ulong eventPoint.lastTimestamp: see also QEventPoint::lastTimestamp
point eventPoint.position: see also QEventPoint::position
point eventPoint.pressPosition: see also QEventPoint::pressPosition

enumeration eventPoint.state: see also QEventPoint::state
real eventPoint.timeHeld: see also QEventPoint::timeHeld
ulong eventPoint.timestamp: see also QEventPoint::timestamp
pointingDeviceUniqueId eventPoint.uniqueId: see also QEventPoint::uniqueId
vector2d eventPoint.velocity: see also QEventPoint::velocity

State supports the following values:

Constant	Description
EventPoint.Unknown	Unknown state; same as Qt.TouchPointUnknownState
