The QProximityReading class represents one reading from the proximity sensor.
QProximityReading_Units The proximity sensor can only indicate if an object is close or not.
The distance at which an object is considered close is device-specific. This distance may be available in the QSensor::outputRanges property.

a value indicating if something is close.
Set to true if something is close. Set to false is nothing is close.
the timestamp of the reading.
Returns the timestamp of the reading.
Sets the close value to close.
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)
