Overview

To write a QML application that will use the gesture plugin, following steps are needed:

Import the QtSensors 5.x module:

import QtSensors 5.0

Add the SensorGesture QML type into your qml file.

    SensorGesture {
id: sensorGesture
enabled: false
onDetected: {
if (gesture !== oldGesture)
count = 0;
valueText.text = gesture + " " + count;
oldGesture = gesture;
count++;
}
onEnabledChanged: {
valueText.text = ""
}
}

Each SensorGesture QML type contains a property called gestures. This example uses an alias gestureId for this property.

    property alias gestureId: sensorGesture.gestures

Then, the gesture or gestures to use can be specified using the alias:

        onSelectedGestureChanged: {
gesture.enabled = false;
gesture.gestureId = gestureList.selectedGesture;
...
}

A list of all available gestures is accessible through the availableGestures property:

        ListView {
id: gestureList
model: gesture.availableGestures
...
}
