qreal
void
Sets the calibration level of the reading to calibrationLevel.

void
Sets the timestamp of the reading.

QVariant
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>();
Note that value() can only access properties declared with Q_PROPERTY() in sub-classes of QSensorReading.
valueCount(), QObject::property()
1.0
int
Returns the number of extra properties that the reading has.
Note that this does not count properties declared in QSensorReading.
