Overview
To write a QML application that will use the gesture plugin you need to to the following steps:
Import the QtSensors 5.x declarative plugin:
import QtSensors 5.0
Add the SensorGesture QML element 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 element contains a property called gestures.
In this example an alias 'gestureid' for this property is used.
property alias gestureid: sensorGesture.gestures
By using this alias property you define which gestures should be used:
onSelectedGestureChanged: {
gesture.enabled = false;
gesture.gestureid = gestureList.selectedGesture;
A list of all available gestures can be created by calling the 'availableGestures' property:
ListView {
id: gestureList
anchors.fill: gestureListRect
anchors.margins: 5
model: gesture.availableGestures
focus: true
currentIndex: -1
delegate: gestureListDelegate
}
