Thanks everybody for your answers.
I swear I will try not to use private method anymore :P

By the way, is there a better than re implement the complete paint method ?
I mean, I just want to change the color of the line according to the "type"
of the node (but not in every view).

@Andreas: I wish I could update my different versions.
But, my unix administration service his quiet... crappy? So they do not want
to upgrade (it's the same for python (2.4), PyQt, and dozen of other library
/ framework). That their politic...
