Detailed Description

The QLightSensor class is a convenience wrapper around QSensor.

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

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

For details about how the sensor works, see QLightReading.

See also QLightReading.
