qt implementation of noodle drawing

I'm wondering if anyone knows of an implementation or library of "noodles" connection diagrams in qt.

I say "noodle", but, I'm not sure what the official name for it is. A diagram connected with what I call noodles is like this:

Attachment 12715

Basically it allows the display of input/output nodes and connecting them with splined lines.

I think this should be possible with QGraphicsScene and QGraphicsView. The Elastic Nodes and Diagram Scene examples are probably useful here. Cubic spline lines can be generated with QPainterPath and added to the scene.
