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().
