Create a new sensor type for distance.
Create a new sensor type for distance. This sensor type supports new hardware sensors that can measure physical distance from the device, in centimeters. The API is designed to mimic the Android API for proximity (TYPE_PROXIMITY), so that if a given proximity sensor only supports a binary measurement (near vs far), then instead of reporting distance in cm, the QDistanceSensor will return the max range value to represent far, and a lesser value to represent close. Using this definition should simplify implementation. The main reason for not implementing this as a new property of QProximitySensor is that clients of QProximitySensor have made the assumption that they will receive the readingReady signal if and only if the reading has changed from near to far or vice versa. Adding a distance property will break that assumption, as distance has a higher degree of precision.
