Re: [Boost-users] [GRAPH]write_graphviz and setS edges

I'd like to use the simple write_graphviz function write_graphviz(std::cout,g);

but since my graph doesn't allow multiple edges between two vertices, the graph type is defined by : typedef adjacency_list Graph;

but then I can't use the write_graphviz function anymore (compilation error). If I declare my graph with typedef adjacency_list Graph; it is fine, but have multiple edges...

So my question is : is there a way to use write_graphviz with the setS edges representation ?

I am not terribly familiar with the write_graphviz interface, so this may not be too helpful. I believe the problem is the manner in which setS and vecS identify vertices (descriptors) in the graph data structure. You may need to provide a vertex index map when you call write_graphviz, possibly using dynamic_properties. Unfortunately, I don't have any examples to point at. Perhaps other users will have encountered and solved the same problem. Andrew Sutton andrew.n.sutton@gmail.com
