详细描述

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.

QAccelerometerReading:: QAccelerometerReading ( QObject * parent = DECLARE_READING(QAccelerometerReading))

Default constructs an instance of QAccelerometerReading.

[虚拟] 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 .

另请参阅 x ().

void QAccelerometerReading:: setY ( qreal y )

Sets the acceleration on the Y axis to y .

另请参阅 y ().

void QAccelerometerReading:: setZ ( qreal z )

Sets the acceleration on the Z axis to z .

另请参阅 z ().
