I'm working on open source software that is basically a graphviz GUI, where nodes (circles, squares, diamonds; QGraphicsItems) are connected via arrows. I have that working. However, I'd like an arrow that points to a single node like in the attached image. Has anyone (1) created these recursive sorts of arrows and (2) created them in such a way as to dynamically adjust to the surface of the QGraphicsItem? If not, can anyone suggest ways to accomplish this functionality? For example, the arrows would "stick" to the surface of any node (circle, square, or diamond)? It would be nice, if this arrow could be moved around the surface of the node (circle, square, diamond, etc.), such that it wouldn't always sit on top, but could moved to the sides.
Thanks, and I'm looking forward to hearing your implementations or opinions on ways to do this. Jeff.
