Re: [Boost-users] Why can't I use boost graph write_graphviz with OutEdgeList=listS and VertexList=listS

Hi

The write_graphviz function requires a vertex_index map, which is not provided by default by graphs with listS as the vertex container.  You can add that property explicitly to a listS graph, and fill it in before the write_graphviz call (after any changes to the graph vertices).

Thanks.... But it is not clear to me how to do this (sorry, i'am quite new to BGL) If I would just like to use the vertes_descriptor pointers as lables, what would that look like?? Do you know about an example I could look at?? -- Allan
