\title Qt Sensors - Cube House QML Accelerometer example
\ingroup qtsensors-examples
\brief The Cube House example demonstrates the use of the accelerometer to drive a camera to create a pseudo-3D effect.
\image cubehouse.png
\section1 Overview
To write a QML application that will use the QML Accelerometer type from the QtSensors import you need to to the following steps:
Import the QtSensors declarative plugin:
\snippet cubehouse/cubehouse.qml 0
Add the Accelerometer QML types into your qml file.
\snippet cubehouse/cubehouse.qml 1
In additional two properties are added to save the calculated pitch and roll values:
\snippet cubehouse/cubehouse.qml 2
Reading out the Accelerometer data can be done by implementing the 'onReadingChanged' slot and
accessing the 'reading' property from the Accelerometer type:
\snippet cubehouse/cubehouse.qml 3
By using a timer the view can be rotated using the pitch and roll properties from the Accelerometer type:
\snippet cubehouse/cubehouse.qml 4
