[Interest] QGeoPositionInfo in QML

[Paolo Angelelli]

Hi Julius,

so there is currently no easy way to have a single interoperable source for position info.
Either you use the C++ source, and QGeoPositionInfo or, QML's PositionSource and Position.

If you want to have the same source, and the data coming from that source in both C++ and QML, i currently see 2
approaches: either you register your own QGeoPositionInfo QML wrapper with accessors, and push objects
of this kind into QML from the C++ source, or you go the other way around, and extract the relevant bits
from a Position in a JS piece of code, and push those into some structure (even a variant map) to C++.

It might be worth considering to (privately?) export PositionSource, so that, if one has specific needs,
could depend on positioning-private, and use the class from Cpp..
