Hi to all,
I want to use the Marble API for viewing the current position of a variable
number of vehicles on a map.
Now my application uses the QtMobility API for visualizing the position of
the vehicles and the track generated.
I want to realize the behavior in this video

For testing the api, I've write a small program, that updates at running

defines the slot updates the geodatatrack with a new point.

At this links there're the worker thread class:

Thank you so much!!
