GLUT/OpenGL question

Hi,
I have a quick question about GLUT/OpenGL if anyone can help.

I have two different screens for a game I'm making (the game screen and a win screen). Both of them have been tested and work fine on their own, but I'm trying to change between them and all I get is a black screen:

void Squares::DisplayGameScreen() {
    glutReshapeFunc(gameScreen->reshapeWrapper);
    glutKeyboardFunc(gameScreen->keyboardWrapper);
    glutDisplayFunc(gameScreen->displayWrapper);
}

void Squares::DisplayWinScreen() {
    glutReshapeFunc(winScreen->reshapeWrapper);
    glutKeyboardFunc(winScreen->keyboardWrapper);
    glutDisplayFunc(winScreen->displayWrapper);
    glutIdleFunc(winScreen->idleWrapper);
}

Is there a correct way to change the display function?

Thanks

The documentation for GLUT says you are doing it right. You could put a breakpoint inside the displayWrapper function to see if GLUT at least calls it correctly.
