Inheriting a new View Class for MDI
-
I'm getting an error when I try to inherit a new view class for a MDI application, and I can't figure out why :/ .. First I created an OpenGL viewport inherited from CView, and packed it with all kinds of functionality. It works great. But now I'm trying to derive a new view class from it, and I'm getting the following error (using VC++ 6.0 professional): C:\DEVELOPMENT\MotionX\MotionX.cpp(119) : error C2039: 'classCMotionXModelView' : is not a member of 'CMotionXModelView' c:\development\motionx\motionxmodelview.h(15) : see declaration of 'CMotionXModelView' C:\DEVELOPMENT\MotionX\MotionX.cpp(119) : error C2065: 'classCMotionXModelView' : undeclared identifier The thing is, I'm just deriving it from a class that is fully functional, and haven't added anything except a member variable to it. This is the view class declaration that works:
