Overview

Writing a QML application that uses the Accelerometer QML sensors type requires the following steps:

Import the Sensors Declarative module.

import QtSensors 5.0

Add an Accelerometer QML type.

    Accelerometer {
id: accel
dataRate: 100

Use the 'active' property to start the sensor

        active:true

Move the bubble according to a factor of the accelerator sensor

        onReadingChanged: {
var newX = (bubble.x + calcRoll(accel.reading.x, accel.reading.y, accel.reading.z)  .1)
var newY = (bubble.y - calcPitch(accel.reading.x, accel.reading.y, accel.reading.z)  .1)
if (isNaN(newX) || isNaN(newY))
return;
if (newX < 0)
newX = 0
if (newX > mainWindow.width - bubble.width)
newX = mainWindow.width - bubble.width
if (newY < 18)
newY = 18
if (newY > mainWindow.height - bubble.height)
newY = mainWindow.height - bubble.height
bubble.x = newX
bubble.y = newY
}
