Hi Daniela,
obviously you cannot set the line width of different lines
individually within the same geoset because geoset::setLineWidth() affects
the entire geoset (so if you invoke later geoset::setLineWidth(5.0) the
first line is also affected). To draw lines at different line width you
have to use different geosets (i.e. geoset1::setLineWidth(1.0),
geoset2::setLineWidth(5.0), ...). This worked fine for me.
