Detailed Description

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.

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
