Detailed Description

The Position element holds various positional data, such as latitude, longtitude, altitude and speed. Not all of these are always available (e.g. latitude and longtitude may be valid, but speed update has not been received or set manually), and hence there are corresponding validity attributes which can be used when writing applications.

The main parameters are writable, so application writer can create his/her own position elements or even store (record) received updates to e.g. later render a walked path.

The Position element is part of the QtMobility.location 1.0 module.

See also PositionSource.
