Maps, Location API, custom plugin and QML

[VTiTux]

Hello,

I scanned some paper maps and I would like to write an app to display them.
Initially, I cut it in small tiles and I wanted to display them by using an GridView and an C++ listModel.

But I discovered the Qt Location API and finally I think that I go to try to create my own plugin map service provider, by sub-classing these classes:
http://doc.qt.digia.com/qtmobility/location-overview.html#implementing-plugins

I'm an beginner in c++, this will be maybe difficult, but I will try.

But I don't understand how to integrate them into QML?
All these classes are for QWidgets.
How to subclasse QGeoMapData::paint() to draw a map into the Quick view?
And how can I call my plugin from the QML?

There is a way to import maps from C++ to QML, like QQuickImageProvider for images?

Is there some documentations that can help me?

Is the QML location API ready for that? Or is it in work in progress?

Thanks.

Ok, I believe that I have to subclasse QQuickPaintedItem or to use the Scene Graphe API.

Hum. I go to use a GridView and a ListModel, it's easier ;-)
