Hi Antonione --
this is a nice start. A couple of suggestions
* you may want to use a gtk.Table for your label/entry pairs in your
dialog editor. Everything will line up much more nicely
* you should not explicitly require pygtk 2.0. Noone is using pygtk1
anymore and this will cause some pygth2 installations to fail (like
mine!)
* you may want to look at the line editor dialog in backend_gtk.py for
inspiration. This uses drop down menus for linestyles, color dialog
boxes to pick colors, etc... I'll paste in the code below
Thanks,
JDH
