OpenGL Initialize Context With GLFW

From IronPython Cookbook

This example demonstrates how to use Tao with the GLFW binding to initialize an OpenGL context.

This has been tested with:

• IronPython 2.0Alpha8 (the original distribution)
• mono 1.2.6 under Ubuntu
• tao 2.0.0 (binary distribution deployed in the gac)
• GLFW 2.6

        Glfw.glfwTerminate()
        return 2

    running = True

    # Loop until the Escape key is pressed or the window is closed
    while running:
        Glfw.glfwSwapBuffers()
        running = ((Glfw.glfwGetKey(Glfw.GLFW_KEY_ESC) == Glfw.GLFW_RELEASE) and
                   Glfw.glfwGetWindowParam(Glfw.GLFW_OPENED) == Gl.GL_TRUE)

    # Shutdown the Glfw context
    Glfw.glfwTerminate()

if __name__ == '__main__':
    run()
