Detailed Description
The QAccelerometerReading class reports on linear acceleration along the X, Y and Z axes.
QAccelerometerReading Units
The scale of the values is meters per second squared. The axes are arranged as follows.
A monoblock device sitting at rest, face up on a desk will experience a force of approximately 9.8 on the Z axis (ie. towards the roof). This is the proper acceleration the device experiences relative to freefall.
Property Documentation
x : const qreal
This property holds the acceleration on the X axis.
The scale of the values is meters per second squared.
Access functions:
| qreal | x() const |
See also QAccelerometerReading Units.
y : const qreal
This property holds the acceleration on the Y axis.
The scale of the values is meters per second squared.
Access functions:
| qreal | y() const |
See also QAccelerometerReading Units.
z : const qreal
This property holds the acceleration on the Z axis.
The scale of the values is meters per second squared.
Access functions:
| qreal | z() const |

Member Function Documentation
QAccelerometerReading::QAccelerometerReading(QObject *parent = DECLARE_READING(QAccelerometerReading))
Default constructs an instance of QAccelerometerReading.
[virtual] QAccelerometerReading::~QAccelerometerReading()
Destroys the instance of QAccelerometerReading. The destructor is virtual.
[override virtual] void QAccelerometerReading::copyValuesFrom(QSensorReading *other)
void QAccelerometerReading::setX(qreal x)
Sets the acceleration on the X axis to x.
See also x().
void QAccelerometerReading::setY(qreal y)
Sets the acceleration on the Y axis to y.
See also y().
void QAccelerometerReading::setZ(qreal z)
Sets the acceleration on the Z axis to z.
See also z().
