Detailed Description
The QPressureReading class holds readings from the pressure sensor.
QPressureReading Units
The pressure sensor returns atmospheric pressure values in Pascals.
Property Documentation
pressure : const qreal
This property holds the measured atmospheric pressure.
Returned as Pascals.
Access functions:
| qreal | pressure() const |
See also QPressureReading Units.
temperature : const qreal
This property holds the pressure sensor's temperature.
The temperature is returned in degree Celsius. This property, if supported, provides the pressure sensor die temperature. Note that this temperature may be (and usually is) different than the temperature reported from QAmbientTemperatureSensor. Use QSensor::isFeatureSupported() with the QSensor::PressureSensorTemperature flag to determine its availability.
This property was introduced in Qt 5.2.
Access functions:
| qreal | temperature() const |
Member Function Documentation
QPressureReading::QPressureReading(QObject *parent = DECLARE_READING(QPressureReading))
Default constructs an instance of QPressureReading.
[virtual] QPressureReading::~QPressureReading()
Destroys the instance of QPressureReading. The destructor is virtual.
[override virtual] void QPressureReading::copyValuesFrom(QSensorReading *other)
void QPressureReading::setPressure(qreal pressure)
Sets the pressure to pressure.
See also pressure().
void QPressureReading::setTemperature(qreal temperature)
Sets the pressure sensor's temperature to temperature.
This function was introduced in Qt 5.2.
See also temperature().
