Hi,
I'm new at marble - I'm using it in my program. (I downloaded the opensouce code)
I couldn't find an answer to the next question:

I'm adding a new gpx file to my map:
marbleWidget->model()->addGeoDataFile(gpxPath);

and then I can see the gpx path on the map, but I cant remove this path, and add another one.
How can I do this - change my gpx file that is shown on the map?
what functions sould I use?

thanks In advance!!

Please use MarbleModel::removeGeoData(QString). The parameter is the filename you used in addGeoDataFile(QString).
