That is interesting. I myself, and most gEDA people, are using GTK. But
I know that today many people enjoy Qt more -- the reason is not always
clear. For GTK we have something similar like QGraphicsView -- Clutter.
I have considered using one of them, but was not really convinced, I
found no great example projects. So for my experimental schematics tool
(http://www.ssalewski.de/PetEd.html.en) I used plain cairo drawing. I
will investigate your program when I have some more free time --
currently I am still very busy -- one of my current open source projects
is my PCB router (http://www.ssalewski.de/Router.html.en), which works
not bad so far, so I really should finish it...

Thanks for the links. I think here in Germany most fab houses still only
use gerber files -- at least that was the case four years ago. Maybe it
already changed.
