[Boost-users] Help using graph library for bundled properties

I just started using the graph library..... I want to store a class I created called bbox as vertices of a graph. So, I just used the bundled properties mentioned as mentioned in the documentation. So here is a relevant portion of the code: vector<bbox> A; boost::adjacency_list<vecS, vecS, undirectedS, bbox> G; for (int i=0; i<A.size(); i++){ for(int j=i+1; j<A.size();j++{ add_edge(A[i], A[j], G); }} But bbox is not accepted as a valid vertex_descriptor for add_edge function. So, how do I go about constructing a graph with a class that I defined as a vertex? Thanks, Abde Ali
