kk but my class ExitListenerAA should not be an abstract class.. i dont derive any other classes from it and i dont have any virtual functions within the code itself so i should be able to call it?
sorry if these are stupid questions this is the first time i tried multiple inheritance and am very shaky on my feet To: [email protected] From: [email protected] Date: Tue, 31 Mar 2009 08:14:15 -0600 Subject: Re: [c-prog] Abstract class hello, If you have an abstract class it just defines the makeup of other classes, and is supposed to be inherited. It's not actually supposed to be called.

I have created a class using multiple inheritance class ExitListenerAA : public FrameListener, public OIS::MouseListener, public OIS::KeyListener { public: ExitListenerAA(OIS::Keyboard *keyboard): mKeyboard(keyboard) //code } In my main code i am creating as follows ExitListenerAA *mListener; mListener = new ExitListenerAA(mKeyboard); On this line i get an error Error 1 error C2259: 'ExitListenerAA' : cannot instantiate abstract class Im just abit confused on how this error comes about. Any help would be great cheers G [Non-text portions of this message have been removed] _________________________________________________________________ Express your personality in color!
