I'd define to/from Python conversions for the std::pair, mapping to Python tuples, then use .add_property().
Alternatively, wrap std::pair the normal way via class_, then you can use .def_readwrite(). You need to handle each std::pair<A,B> combination of A,B separately, like any other template class you want to wrap or convert to/from a Python object. See also: http://www.boost.org/doc/libs/1_37_0/libs/python/doc/v2/faq.html#custom_string This could be a starting point for std::pair<A,B> conversions. Probably you want to make it into a converter template if you have more than one combination of A,B. Here is code we use for the to_python conversions: http://cci.lbl.gov/cctbx_sources/boost_adaptbx/ std_pair_conversion.h std_pair_ext.cpp We don't have corresponding from_python conversions. If you add them, let me know! The next item in the FAQ is also relevant. ----- Original Message ---- From: Ricardo Abreu <gumb...@gmail.com> To: cplusplus-sig@python.org Sent: Monday, January 19, 2009 7:27:46 AM Subject: [C++-sig] Exposing members of members Hello, Suppose that I have a class A with a member of type std::pair, called a. If I want to expose class A to python while allowing read/write access to the object pointed to by a.first, what to I put in def_readwrite? I tried something like class<A>("A").def_readwrite("a", &A::a::first); but it doesn't work. Also been trying with boost::bind but didn't have any luck :s I know I could do getters and setters, but there would be a lot of them because my "A" has a lot of members like "a". Thank you in advance, Ricardo _______________________________________________ Cplusplus-sig mailing list Cplusplus-sig@python.org http://mail.python.org/mailman/listinfo/cplusplus-sig
