[pygccxml-development] Exporting boost::optional<wstring> member variables with Py++

[Roger D. <rd...@da...>]

Hello everyone,

I'm having trouble exporting boost::optional<wstring> member variables 
and I was wondering if someone here might be able to help. I have 
boost::optional to_python and from_python converters that I can manually 
invoke like so:

typedef return_value_policy<return_by_value> rbv;
typedef default_call_policies dcp;
...
.add_property("membervar", make_getter(&myclass::membervar, rbv()), 
make_setter(&myclass::membervar, dcp()))

When I try to use Py++ to export this member variable, it generates code 
like this:

.def_readwrite("membervar", &myclass::membervar)

I have hundreds of these boost::optional<wstring> member variables. Is 
there a way to make Py++ generate code like the .add_property example? I 
have searched in the documentation and have found the variable_wrapper 
module. It looks like it might do the trick, but I can't tell how to use it.

Any help would be much appreciated.

Thank you,

Roger
