[Marble-devel] Problem with MarbleWidget

[Tommaso Fabbri]

Hi Dennis,
thank you for your reply.
I've solved the problem by removing and adding the GeoDataDocument in the
slot function:

map->model()->treeModel()->removeDocument(doc);
lon += 0.001;
lat += 0.005;
cout << "[MAPSLOT] Add Point" << endl;
line->append(GeoDataCoordinates(lon,lat,0,GeoDataCoordinates::Degree));
map->model()->treeModel()->addDocument(doc);

Thank you so much!
