    <p>I am trying to expose a C++ library to python using boost-python. The library actually wraps an underlying C api, so uses raw pointers a lot. </p> <pre><code>// implementation of function that creates a Request object inline Request Service::createRequest(const char* operation) const { blpapi_Request_t *request; ExceptionUtil::throwOnError( blpapi_Service_createRequest(d_handle, &amp;request, operation) ); return Request(request); } // request.h class Request { blpapi_Request_t *d_handle; Element d_elements; Request&amp; operator=(const Request&amp; rhs); // not implemented public: explicit Request(blpapi_Request_t *handle); Request(RequestRef ref); Request(Request &amp;src); }; // request.cpp BOOST_PYTHON_MODULE(request) { class_&lt;blpapi_Request_t&gt;; class_&lt;Request, boost::noncopyable&gt;("Request", init&lt;blpapi_Request_t *&gt;()) .def(init&lt;Request&amp;&gt;()) ; } </code></pre> <p>Although request.cpp compiles successfully, when I try and use the object I get the following error:</p> <pre><code>// error output TypeError: No to_python (by-value) converter found for C++ type: class Request </code></pre> <p>In-order to call this the python code looks like:</p> <pre><code>from session import * from service import * from request import * so = SessionOptions() so.setServerHost('localhost') so.setServerPort(8194) session = Session(so) # start sesssion if not session.start(): print 'Failed to start session' raise Exception if not session.openService('//blp/refdata'): print 'Failed to open service //blp/refdata' raise Exception service = session.getService('//blp/refdata') request = service.createRequest('ReferenceDataRequest') </code></pre> <p>The other objects (SessionOptions, Session, Service) etc are also c++ objects that I have successfully created boost-python wrappers for.</p> <p>As I understand from the boost-python docs this has something to do with passing a raw pointer around, but I don't really understand what else I should do ...</p>

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.
