Hello,

As I didn't get any hints to existing solutions for how to enter points,
segments,
or polylines in the GraphicsView framework, we came up with a solution in
the CGAL 
project.

For those who have similar problems, please have a look at
http://www.cgal.org/Manual/3.4/doc_html/cgal_manual/GraphicsView/Chapter_main.html

Any feedback is highly welcome.

best regards,

andreas
