[Freeglut-developer] Gamemode on Windows

[Eero P. <epa...@ko...>]

Does anybody remember breaking gamemode on Windows during
fall/winter? ;-)

In my development side I run my program in a window,
and I have been slow at updating freeglut for my
"production side", so I unfortunately cannot really
say what has happened and when, but now I am having problems
with gamemode.

My code does something like:

   glutInitWindowPosition(0,0);
   glutInitWindowSize(SCREEN_WIDTH(),SCREEN_HEIGHT());
   glutInitDisplayString("double rgb depth>=24");

   if (!in_window){
     glutGameModeString(screen_mode);
     if(0 == (win=glutEnterGameMode())) {

So it might be that my InitWindowSize call etc are part
of the problem, but I suspect that. (glutInitWindowSize
gives my preferred window size, the screen size in glutGameMode
is something quite different, and I think there anyways is a
default window size which is NOT the 2048x768 size I want...)

This is my current analysis of the problem:

When I call glutEnterGameMode it ends up
calling the (Win32) CreateWindow with correct size,
but that activates fgWindowProc with the WM_CREATE message.

In fgWindowProc there is code: (about line 1208)

       window->State.NeedToResize = GL_TRUE;
         window->State.Width  = fgState.Size.X;
         window->State.Height = fgState.Size.Y;

This stuffs my gamemode window with an the size specified
in glutInitWindowSize, and sets it up for resize.

On the next window redraw the the window gets sour.


I assume I will hack my self around this, but unless there
is something wrong with my setup, a proper fix is needed.
