I would like to change the width (left and right), directly from the Properties form.
In the API, sample lines don´t have the left width and right width for writing them, I think that they are only for read. (In my app, I can put the coordinates of the extrems of the sample line, but I have to calculate those coordinates and I would prefer not to do it if I could put directly the width).
Moreover, if I drag a sample line on the alignment, put directly the station in the command line. I can only change the station in the properties form.
