Let's say I'm a Qt newbie. I want a good Qt library for displaying simple graphs. I've found the quanava library. But there is a problem. When I compiled a basic example it looks like graph edges are not painted properly when moving nodes. I don't have any idea where is a bug but this code seems to be rather simple. I think this is a problem with paint method in NodeItem class. Maybe someone has already solved this problem because this library is quite popular.
