OpenGL - Refreshing window without gl***func( .... ) ?

Hi All,

in fact, I want to manually handle the refreshing of the app window without using all the glut functions like :
glutDisplayFunc, glutIdleFunc, nor calling glutMainLoop ... is this possible ?

Does someone have a tutorial about doing this ?

Thank you.

Regards,
Fred

i have only tutorials about open gl and glglut.. sorry and honestly i don't know how could you handle an opengl refreshing action, without using an opengl function..

GLUT is optional. SDL can open an OpenGL context without GLUT. It has a special command for page flipping under OpenGL also. See SDL_GL_SwapBuffers and for more information see SDL_GL_SetAttribute.

I am honestly not quite sure what you want to achieve, but if I get this correctly, you want to use MiniGL without GLUT. If that is the case, look at the RasOnly or Warp samples in the MiniGL archive, they don't use GLUT IIRC.
Seriously, if you do want to contact me write me a mail. You're more likely to get a reply then.

In fact, I use GLUT for what it simplify life but about refreshing screen, I don't want to use the automatic functions because they are too restrictive for what I want to do ;)
I have found.
Simply using glutSwapBuffers() works fine even in simple buffered mode :p

Normally, you would use glutPostRedisplay() for this effect.
