Hi,
I'm trying to find some solution to my problem but without succes. I need to be
able to export C++ class constructor that takes arbitraty arguments (as in
python __init__(self, *args, **kwargs). Is it possible to have this kind of
constructor? I've tried something like this:
BOOST_PYTHON_MODULE(main)
{ class_<Form, boost::noncopyable, boost::shared_ptr<Form>>("Form") ;
}
then in main:
...
try {
object main = import("__main__"); object global(main.attr("__dict__"));
boost::python::dict local;
exec( "import main\n" "class Form1(main.Form):\n"
" def __init__(self, A, *args, **kwargs):\n"
" super().__init__(*args, **kwargs)\n\n" , global, local); // Get class
object c_form1 = local["Form1"]; // Create instance
object form1_instance = object(handle<>(PyObject_CallObject(c_form1.ptr(), make_tuple(1, 2).ptr())));
}
catch(error_already_set &)
{ PyErr_Print();
}
But it prints:
Traceback (most recent call last):
File "<string>", line 4, in __init__
Boost.Python.ArgumentError: Python argument types in
Form.__init__(Form1, int)
did not match C++ signature:
__init__(struct _object *)
Which is logical I think because it finds only default constructor. I've tried
also raw_constructor from
http://wiki.python.org/moin/boost.python/HowTo#A.22Raw.22_constructor but
without success.
Anyone know if it is somehow possible?
Thanks
Trigve
