Body
I know this might be obvious, but bear with me my generic programming background is weak. This is the code I am trying to compile : <pre><code>#define BOOST_GRAPH_USE_NEW_CSR_INTERFACE #include <boost/graph/compressed_sparse_row_graph.hpp> #include <vector> typedef unsigned int uint32_t; typedef unsigned long uint64_t; using namespace boost; using namespace std; typedef compressed_sparse_row_graph<directedS,void,void,no_property,uint32_t,uint64_t> intl_graph; typedef std::pair<uint32_t,uint32_t> E; int main() { intl_graph g; vector<E> the_edges; uint32_t nv = 3; uint64_t nedge; the_edges.push_back(E(0,1)); the_edges.push_back(E(1,2)); g = intl_graph(edges_are_unsorted_t,the_edges.begin(),the_edges.end(),nv); //line 24 } </code></pre> which results in this error : <pre><code>boost_eg.cpp: In function âint main()â: boost_eg.cpp:24: error: expected primary-expression before â(â token boost_eg.cpp:24: error: expected primary-expression before â,â token </code></pre> If I change line 24 to this : <pre><code>intl_graph g_(edges_are_unsorted_t,the_edges.begin(),the_edges.end(),nv); </code></pre> the error is this : <pre><code>boost_eg.cpp: In function âint main()â: boost_eg.cpp:24: error: âthe_edgesâ is not a type boost_eg.cpp:24: error: expected â,â or â...â before â.â token </code></pre> Any thoughts?

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
