Description
I saw this on a Linux laptop that had a built in pen/touch screen (X1 Carbon Yoga laptop). Using a stylus, I had this setup:
PointHandler {
id: pen_point_handler acceptedDevices: PointerDevice.Stylus
acceptedPointerTypes: PointerDevice.Pen onPointChanged: {
// Log info about the point that's been pressed
var id = pen_point_handler.point.id;
console.log("Pen");
console.log(" id: " + id);
console.log(" uid: " + pen_point_handler.point.uniqueId);
console.log(" pos: " + pen_point_handler.point.position);
console.log(" pressure: " + pen_point_handler.point.pressure);
console.log(" rotation: " + pen_point_handler.point.rotation);
console.log("----");
}
}
Output on the console looked like this:
qml: Pen qml: id: 0 qml: uid: QPointingDeviceUniqueId(1002769070) qml: pos: QPointF(754.538, 339.569) qml: pressure: 0.4407806396484375 qml: rotation: -180 qml: ---- qml: Pen qml: id: 0 qml: uid: QPointingDeviceUniqueId(1002769070) qml: pos: QPointF(754.538, 339.569) qml: pressure: 1 qml: rotation: 0 qml: ---- qml: Pen qml: id: 0 qml: uid: QPointingDeviceUniqueId(1002769070) qml: pos: QPointF(756.772, 339.693) qml: pressure: 0.3406524658203125 qml: rotation: -180 qml: ---- qml: Pen qml: id: 0 qml: uid: QPointingDeviceUniqueId(1002769070) qml: pos: QPointF(756.772, 339.693) qml: pressure: 1 qml: rotation: 0 qml: ---- qml: Pen qml: id: 0 qml: uid: QPointingDeviceUniqueId(1002769070) qml: pos: QPointF(758.82, 339.942) qml: pressure: 0.25372314453125 qml: rotation: -180 qml: ---- qml: Pen qml: id: 0 qml: uid: QPointingDeviceUniqueId(1002769070) qml: pos: QPointF(758.82, 339.942) qml: pressure: 1 qml: rotation: 0 qml: ---- qml: Pen qml: id: 0 qml: uid: QPointingDeviceUniqueId(1002769070) qml: pos: QPointF(760.186, 340.252) qml: pressure: 0 qml: rotation: -180 qml: ---- qml: Pen qml: id: 0 qml: uid: QPointingDeviceUniqueId(1002769070) qml: pos: QPointF(760.186, 340.252) qml: pressure: 1 qml: rotation: 0 qml: ----
For each point that was being registered, I'm getting second one that has its pressure information set to `1`.
When I had the `PointHandler` only accept touch screen (finger presses) and mouse input, I wasn't getting these double-emits for each point.
