Is it possible to call the function

int main(int argc, char **argv)
{
    glutInit(&argc, argv);
    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
    glutInitWindowSize(500, 500);
    glutInitWindowPosition(100, 100);
    glutCreateWindow("Window");
    glutDisplayFunc(display);
    glutIdleFunc(display);
    glutReshapeFunc(reshape);
    glutMotionFunc(mouseMovement); //check for mousemovement
    glutKeyboardFunc(keyboard);
    glutMainLoop();
    return 0;
}

inside a button click event like below ? where display,keyboard etc are different functions

private: System::Void button1_Click(System::Object^  sender, System::EventArgs^  e) 
    {
          main(); -------(Not sure of syntax)
    }

What I have tried:

tried declaring the main function in .h file instead of .cpp but didn't work.

GLUT is simple lightweight GUI framework for using (and mostly learning) OpenGL. If you want to use OpenGL in UI program (Windows API, C++/CLI, MFC or any other UI toolkit), use OpenGL directly without GLUT.

OpenGL directly without GLUT ? Can you please elaborate or share a link for the said information. To my knowledge OpenGL was just a library without an GUI .

No, one should not call main from anywhere. It is the designated entry point for CLI programs. For GUI programs in windows the entry point is WinMain.

This is a bit confusing. How is it you have a button in a window with a CLI program?

If you want to learn how to use OpenGL in a WinForms app there are several articles here that describe it. A search at this site turns up these: CodeProject Search[^]
