hi all,
i've got a problem with a python class, that i'm deriving from two classes. one of the base classes is a class from pyqt, the other one is a wrapped boost.python class.
now, when deriving my class from these two classes, i'm getting the message: TypeError: Error when calling the metaclass bases metaclass conflict: the metaclass of a derived class must be a (non-strict) subclass of the metaclasses of all its bases
any idea, how to solve the metaclass conflict? my boost.python class has the structure: class_<my_wrapper, boost::noncopyable>("my_class") .def("my_fun", &my_wrapper::my_fun);
The problem you are facing is that there are certain constraints on the metaclasses of your (multiple) base classes: http://www.python.org/download/releases/2.2/descrintro/#metaclasses I don't know pyqt, and I'm not sure you get access to boost.python's own metaclass. (David ?) You may need to derive a new metaclass from boost.python's one as well as the pyqt metaclass. HTH, Stefan -- ...ich hab' noch einen Koffer in Berlin...
