I've been exploring C++/Python binding layers. The two that interest me the most are Boost.Python and Shiboken. Looking at PySide and also libsample/samplebinding that ships with Shiboken, I've seen that the following behaves as one would expect:
a = ObjectType() b = ObjectType() b.setParent(a) assert(a is b.parent()) I've tried something similar in Boost.Python, but I cannot get the assertion to pass. It seems that Boost.Python will generate a new python wrapper each time you call b.parent(), so the ID of the returned object changes at each call (even though it is the same C++ object being returned). How does Shiboken ensure the same Python object is returned at each call to parent()? Since PySide started out in Boost.Python, was that able to support this behavior using Boost, or was that part of the motivation in creating a new binding generator? Thanks! Nathan
