Thank you for your reply, but I encountered this error with the define_key in pview.cxx
error C2664: 'PandaFramework::define_key' : cannot convert parameter 3 from 'void (__cdecl *)(CPT_Event,void *)' to 'EventHandler::EventCallbackFunction (__cdecl *)'Needless to say, it didn’t quite work out in my own test code either (same error obviously). Is this is a version 1.4.0 issue? I use VC8 for compiling.
