I guess you would have to do something like this:

  void rotateY( void * ) {
      // rotate the scene
  }


  int main() {
      // set up the standard framework
   
      interactor->SetLeftButtonPressMethod( rotatY, 0 );

      // do some more stuff

      return 0;
  }


Note that if you want the function given as a parameter to be a function
in a class, you'll have to do something a little different.
