Detailed Description
The QMagnetometer class is a convenience wrapper around QSensor.
The only behavioural difference is that this class sets the type properly.
This class also features a reading() function that returns a QMagnetometerReading instead of a QSensorReading.
For details about how the sensor works, see QMagnetometerReading.
See also QMagnetometerReading.
Property Documentation
returnGeoValues : bool
This property holds a value indicating if geomagnetic values should be returned.
Set to true to return geomagnetic flux density. Set to false (the default) to return raw magnetic flux density.
The property must be set before calling start().
Access functions:
| bool | returnGeoValues() const |
| void | setReturnGeoValues(bool returnGeoValues) |
Notifier signal:
| void | returnGeoValuesChanged(bool returnGeoValues) |
Member Function Documentation
QMagnetometer::QMagnetometer(QObject *parent = Q_NULLPTR)
Construct the sensor as a child of parent.
[virtual] QMagnetometer::~QMagnetometer()
Destroy the sensor. Stops the sensor if it has not already been stopped.
QMagnetometerReading *QMagnetometer::reading() const
Returns the reading class for this sensor.
See also QSensor::reading().
