[Freeglut-developer] glutFullScreen

[<joc...@la...>]

Hello,

While trying to fix glutFullScreen() for X11, I wonder about what this
function should really do.

GLUT specification states that “Subsequent glutReshapeWindow and
glutPositionWindow requests on the window will disable the full screen
status of the window.”, which is not really clear to me. Or maybe I just
don't get the point.

It seems to me that current window managers (and so applications) handle
full screen as follows :
- while in full screen state, a window cannot be moved or resized,
- when leaving full screen state, the previous window's position and
   size are restored.

I suggest that freeglut behaves the same way. While the window is in
full screen state, a call to glutFullScreen() should restore it to
normal state. User could possibly call glutGet() to know if the window
is in full screen state or not.

What do you think about it? And what should glutReshapeWindow() and
glutPositionWindow() do when full screen is on : restoring the window to
its previous state before processing or do nothing at all?
