Quick Syntax Issue

I have the following code:
===============================================

#include "globals.h"
#include "ftApp.h"

#include <GL/glut.h>


ftApp::ftApp(int argc, char **argv)
{
      // Standard GLUT init
      glutInit(&argc,argv);
      glutInitDisplayMode(GLUT_DOUBLE | GLUT_RGB);
      glutInitWindowSize(WINDOW_START_WIDTH, WINDOW_START_HEIGHT);
      glutCreateWindow(WINDOW_TITLE);

      // GLUT callback functions
      glutDisplayFunc(ftApp::DrawScene);

      this->SetupRenderContext();
}


void ftApp::SetupRenderContext(void)
{
      glClearColor(CLEAR_COLOR);
}


void ftApp::Start(void)
{
      glutMainLoop();
}


void ftApp::DrawScene(void)
{
      glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
      glMatrixMode(GL_MODELVIEW);
      glLoadIdentity();
      glutSolidTeapot(0.5);
}

===============================================

On compile, following error occurs:

...\ftApp.cpp(16): error C2664: 'glutDisplayFunc' : cannot convert parameter 1 from 'void (void)' to 'void (__cdecl *)(void)'

===============================================

I think it is obvious what I am trying to do.  How do I do it?

Thanks,

Justin
