boost-graph

I am investigating the use of the boost graph libraries in order to apply them to various network problems I have in mind.

In the examples I have been looking at the graph edge values ("weights") are always initialized as integers, such as in these Bellman-Ford and Kruskal algorithms eg:

int weights[] = { 1, 1, 2, 7, 3, 1, 1, 1 };

My problem is if I try and change the weights to double, I get a heap of warning messages about conversions etc, which so far I have not been able to figure out how to overcome.

Does anyone see a way around this?

Can anyone please tell me that once I've created a graph using Boost Graph library, how can I display that graph? My biggest concern is that the edge weights are coming from an exernal data source over the network. And I need to be able to display the edgeweights live as they get updated. >>> More
