Hi all,

I'm loading a gpx file to marble through MarbleModel::addGeoDataFile . and then I want to add a point to the end of the track on the gpx file.
I used GeoDataTrack::appendCoordinates to do that, but all I got on the map, is a stright line - that from the last point on my gpx file to the new point I added.

what I really want to do, is to consider my new added point as a part of the track - and instead of creating a streight line from the last point on my gpx file to the new point I added manually, I want to see a path that passes only car rodes.

how can I do that?
