I'm trying to wrap a C++ class into python. I need to pass an enum value by
reference through a virtual function. I'm doing it like so (non relevant code
omitted):
class BasicRMLScreenWrap : public BasicRMLScreen {
public: bool HandleKeyPressedDefault(const sf::Uint32
time, const ::Input::InputModule* inputModule, ::Input::PlayerInput pinput,
::Input::InputAction& iaction) {
return BasicRMLScreen::HandleKeyPressed(time, inputModule, pinput, iaction);
} bool HandleKeyReleased(const sf::Uint32
time, const ::Input::InputModule* inputModule, ::Input::PlayerInput pinput,
::Input::InputAction& iaction) override {
return call_method<bool>(self, "HandleKeyReleased", time,
ptr(inputModule), pinput, boost::ref(iaction)); }
private: PyObject* self; };
class_<BasicRMLScreen, bases<GameScreen>,
boost::shared_ptr<BasicRMLScreenWrap>, boost::noncopyable >("BasicRMLScreen",
init<const std::string&, const std::string&, Engine*, int>())
.def("HandleKeyPressed", &BasicRMLScreen::HandleKeyPressed,
&BasicRMLScreenWrap::HandleKeyPressedDefault) ;
the problem is that when I wrap it like this, I get the following error:
Error 74 error C2664: 'boost::mpl::assertion_failed' : cannot convert
parameter 1 from 'boost::mpl::failed ************boost::mpl::or_<T1,T2>::*
***********' to 'boost::mpl::assert<false>::type'
if I switch boost::ref(iaction) to iaction it compiles fine, but I need to pass
it by ref for correct behaviour. I'm not sure if this is a boost::ref problem
or a boost python issue but was curious if someone might have an idea how to
correct it. I can pass using boost:ref fine in the other places ive used it
with call_method. Is this is an issues because it's an enum?
Any help would be appreciated,
thanks _______________________________________________
