Hello everybody,

For my student project, i should build a GUI for a compiler about a small langage , ( see http://meusburger.net/matthias/CV/Mi...grammaire.html)
and we should add features for debugging a simple program for example breakpoints or step-by-step instruction evaluation.
I have choice Qt4.2.0 for that and I have no idea how doing a sourceview where i can add breakpoint like some IDE with line number ( like this http://qdevelop.org/captures/debugging.png
) I have tried to open ui file from QIde with Designer but he crash !

So if someone could me explain how this widget could be build I am very interesting ....

Thanks.

ps: excuse me for my bad English ..
