It already does this. VisualEdge, like VisualVertex, implements 
VisualGraphComponent  which has an overloaded setGeneralPath() to define the 
line segments that make up the drawing. It either takes a 
java.awt.geom.GeneralPath or a java.awt.geom.PathIterator.

Well, if you mean interactively ... it does not have to be in GraphEditor. 
You can create your own class to do that.

It also serializes these segments as well into XGMML. See the 
serializerVertex() and serializeEdge() methods of GraphToXGMMLSAXHandler. 
These segments are also read back from XGMML .
