Re: [Openjgraph-development] VisualEdge composed of many line segments

Maybe a little clarification is in order.

Execute runsample1.sh ( or runsample1.bat for windows ). You would see two 
graphs. Hit the layout button on the right, then drag one of the vertices. 
You should see an edge being drawn orthogonally ( vertical and horizontal 
lines only ) instead of being drawn straight.

Now OpenGraph also reads and writes them back to XGMML. BUT ..... the problem 
is keeping track of the state, which is not saved into XGMML. This state 
tells the layout manager things like which "port" in each vertex is the 
orthogonal edge connected to. The end result is that, although you have read 
the orthogonal edge from XGMML, it is not displayed properly. ( See the 
Release Notes for 0.9.0 under XGMML ).

Maybe my understanding of XML is not clear, or maybe GraphXML is better 
suited for these kind of things ....
