I will explain this more.
First I have a c++ class like this:
struct object
{
object(object *parent=0) // if parent !=NULL append this at
parent children list
~object() //Destroy all children
};
Is possible implement this using "python::with_custodian_and_ward_postcall"?
I tried some like that:
qclass_<object_wrapper, boost::noncopyable > ("object", python::init<> ())
//here i put self will be the ward and arg 2 (parent) will be the
custodian or
.def(python::init<object*>()[python::with_custodian_and_ward_postcall<2,1>()])
