    \brief The QProximityReading class represents one reading from the
           proximity sensor.

    \target 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.
*/

/*!
    \property QProximityReading::close
    \brief a value indicating if something is close.

    Set to true if something is close.
    Set to false is nothing is close.

    The only behavioural difference is that this class sets the type properly.

    This class also features a reading() function that returns a QProximityReading instead of a QSensorReading.
