详细描述

The QGyroscopeReading class represents one reading from the gyroscope sensor.

QGyroscopeReading Units

The reading contains 3 values, measured in degrees per second that define the movement of the device around the x, y and z axes. Unlike QRotationReading , the values represent the current angular velocity rather than a fixed rotation. The measurements are in degrees per second.

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

Default constructs an instance of QGyroscopeReading.

[虚拟] QGyroscopeReading:: ~QGyroscopeReading ()

Destroys the instance of QGyroscopeReading. The destructor is virtual.

[override virtual] void QGyroscopeReading:: copyValuesFrom ( QSensorReading * other )

void QGyroscopeReading:: setX ( qreal x )

Sets the angular velocity around the x axis to x .

另请参阅 x ().

void QGyroscopeReading:: setY ( qreal y )

Sets the angular velocity around the y axis to y .

另请参阅 y ().

void QGyroscopeReading:: setZ ( qreal z )

Sets the angular velocity around the z axis to z .

另请参阅 z ().
