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

Hi Dave,

It is still not clear. What should my parameters be for the function add_edge() to construct the graph with bbox objects as edges?

I'm not sure how to answer you helpfully because there seem to be a few misconceptions here. To start with, the edge properties are not the edges themselves; they're just associated properties. Secondly, the graph you've declared doesn't specify any bundled edge properties; it specifies bbox as a bundled vertex property. ...but the straightforward answer to your question is that the first two parameters to add_edge should be vertex descriptors, usually as obtained from the add_vertex function.

Thanks,
