Qt Sensors in QML¶
The QtSensors - QML example demonstrates the QML sensors types in the QtSensors 5 import.
To write a QML application that will use the QML sensors types in the QtSensors 5 import you need to to the following steps:
Import the QtSensors 5.x declarative plugin:
import QtSensors 5.0Add the Sensor QML types into your qml file.
In this example we use the TiltSensor :
TiltSensor { id: tilt active: false }The Tilt-, AmbientLight- and the Proximity QML sensor types have the ‘enabled’ property in common. To start or stop the sensor set this property to true or false.
tilt.active = (tiltStart.text === "Start");Reading the data can be done for each sensor type like following:
TiltSensor
text: "X Rotation: " + (tilt.reading ? tilt.reading.xRotation.toFixed(2) + "°" : "Unknown") text: "Y Rotation: " + (tilt.reading ? tilt.reading.yRotation.toFixed(2) + "°" : "Unknown")AmbientLightSensor
onReadingChanged: { if (reading.lightLevel == AmbientLightReading.Dark) ambientlighttext.text = "Ambient light: Dark"; else if (reading.lightLevel == AmbientLightReading.Twilight) ambientlighttext.text = "Ambient light: Twilight"; else if (reading.lightLevel == AmbientLightReading.Light) ambientlighttext.text = "Ambient light: Light"; else if (reading.lightLevel == AmbientLightReading.Bright) ambientlighttext.text = "Ambient light: Bright"; else if (reading.lightLevel == AmbientLightReading.Sunny) ambientlighttext.text = "Ambient light: Sunny"; else ambientlighttext.text = "Ambient light: Unknown"; }ProximitySensor
text: "Proximity: " + (proxi.active ? (proxi.reading.near ? "Near" : "Far") : "Unknown")
