The QPressureReading class holds readings from the pressure sensor.
Public Functions Index
Protected Functions Index
The measured atmospheric pressure.
The pressure sensor's temperature.
The temperature is returned in degree Celsius. This property provides the pressure sensor die temperature. Note that this temperature may be (and usually is) different than the temperature reported from QAmbientTemperatureSensor.
the timestamp of the reading.
Returns the timestamp of the reading.
Sets the pressure to pressure.
Sets the pressure sensor's temperature to temperature.
Sets the timestamp of the reading.
Returns the value of the property at index.
Note that this function is slower than calling the data function directly.
Here is an example of getting a property via the different mechanisms available.
Accessing directly provides the best performance but requires compile-time knowledge of the data you are accessing.
QAccelerometerReading *reading = ...; qreal x = reading->x();
You can also access a property by name. To do this you must call QObject::property().
qreal x = reading->property("x").value<qreal>();
Finally, you can access values via numeric index.
qreal x = reading->value(0).value<qreal>();
(Only has inherited protected functions)
