Detailed Description
The only behavioural difference is that this class sets the type properly.
This class also features a reading() function that returns a QRotationReading instead of a QSensorReading.
For details about how the sensor works, see QRotationReading.
See also QRotationReading.
Property Documentation
hasZ : const bool
This property holds a value indicating if the z angle is available.
Returns true if z is available. Returns false if z is not available.
Access functions:
| bool | hasZ() const |
Notifier signal:
| void | hasZChanged(bool hasZ) |
Member Function Documentation
QRotationSensor::QRotationSensor(QObject *parent = Q_NULLPTR)
Construct the sensor as a child of parent.
[virtual] QRotationSensor::~QRotationSensor()
Destroy the sensor. Stops the sensor if it has not already been stopped.
QRotationReading *QRotationSensor::reading() const
Returns the reading class for this sensor.
See also QSensor::reading().
void QRotationSensor::setHasZ(bool hasZ)
Sets whether the z angle is available to hasZ. This is to be called from the backend. By default the hasZ property is true, so a backend only has to call this if its rotation sensor can not report z angles.
This function was introduced in Qt 5.1.
See also hasZ().
