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.
