GLUT - Creating a fullscreen applications.

To create a fullscreen application must use the function:
glutGameModeString()
glutEnterGameMode()
Below is the source commented.

import sys
from OpenGL.GL import *
from OpenGL.GLUT import *

def main():
 
    # Initialize OpenGL
    glutInit(sys.argv)
    glutInitDisplayMode(GLUT_DOUBLE | GLUT_RGB)
 
    # Configure the display output
    glutGameModeString("1024x600:32@60")

    # The application will enter fullscreen
    glutEnterGameMode()
 
    # Setup callbacks for keyboard and display
    glutKeyboardFunc(keyboard)
    glutDisplayFunc(display)
 
    # Enters the GLUT event processing loop
    glutMainLoop()
 
def keyboard(key, x, y):
    if key == 'q':
        sys.exit(0)

def display():
    glClear(GL_COLOR_BUFFER_BIT)

    # Draw a green line
    glBegin(GL_LINES)
    glColor3f(0.0,100.0,0.0)
    glVertex2f(1.0, 1.0)
    glVertex2f(-1.0, -1.0)
    glEnd()
 
    glutSwapBuffers()
 
if __name__ == "__main__":
    main()
