Hey All,
I was working on a project a few months ago where I
was wrapping a lib ( using Boost.Python ) that inherited
from classes that were already wrapped ( using SIP ).
Boost.Python however couldn't find the base classes. I
hacked something up ( that I'm not very proud of ) in class.cpp :
type_handle get_class(type_info id)
{
type_handle result(query_class(id));
if (result.get() == 0)
{
PyObject* globals = PyEval_GetGlobals() ;
PyObject* key = object( id.name() ).ptr() ;
PyObject* obj = PyDict_GetItem( globals, key );
if( obj ){
return type_handle( obj->ob_type );
}else{
object report("extension class wrapper for base class ");
report = report + id.name() + " has not been created yet";
PyErr_SetObject(PyExc_RuntimeError, report.ptr());
throw_error_already_set();
}
}
return result;
}
Surely there has to be a better way. Does anyone have a
better solution than this?
This was also followed by metaclass and layout conflicts,
but that's another issue I think.
To give a little background I was trying to wrap a lib that
inherits from Qt and I really would prefer to use the
bindings from PyQt rather than re-wrap ( which also seems
more difficult than I thought it would be ).
Thanks,
Alex.
