The QAccelerometerReading class reports on linear acceleration along the X, Y and Z axes.
The accelerometer returns acceleration values along 3 axes. 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.
This property holds the acceleration on the X axis.
Access functions:
qreal | x () const |
This property holds the acceleration on the Y axis.
Access functions:
qreal | y () const |
This property holds the acceleration on the Z axis.
Access functions:
qreal | z () const |
Sets the acceleration on the X axis to x.
See also x().
Sets the acceleration on the Y axis to y.
See also y().
Sets the acceleration on the Z axis to z.
See also z().
