      Using a tablet like Wacom with stylus and eraser doesn't work with QML items, such as TapHandler.
      Setting:

          app.setAttribute(Qt::AA_SynthesizeMouseForUnhandledTouchEvents, false);
    app.setAttribute(Qt::AA_SynthesizeMouseForUnhandledTabletEvents, false);

      Makes it not working at all.

      Please run the example code bellow:

      import QtQuick 2.12
import QtQuick.Window 2.12

Window {
    id: root
    visible: true
    width: 1024
    height: 768
    title: qsTr("Hello World")

    Item {
        id: glassPane
        z: 10000
        anchors.fill: parent
        PointHandler {
            id: handler
            acceptedDevices: PointerDevice.Stylus | PointerDevice.Eraser
            target: Rectangle {
                parent: glassPane
                color: "red"
                visible: handler.active
                x: handler.point.position.x - width / 2
                y: handler.point.position.y - height / 2
                width: 20; height: width; radius: width / 2
            }
        }
    }
}

      In case the documentation should mention it, that it is not supported.
