Returns the timestamp of the reading.
Sets the ambient light level to lightLevel.
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)
