SDL window positioning

Recommended Posts

Not in any SDL version so far. However I think in SDL 1.3 this will finally be fixed. Best thing you can do for now is using native functions for your platform, for example use this to center the window:


#include <SDL_syswm.h>
void
CenterWindow(int w, int h)
{
int x,y;
SDL_SysWMinfo info;
SDL_VERSION(&info.version);
if(SDL_GetWMInfo(&info) > 0)
{
# if defined(WIN32)
x = GetSystemMetrics(SM_CXSCREEN) / 2 - w / 2;
y = GetSystemMetrics(SM_CYSCREEN) / 2 - h / 2;
MoveWindow(info.window, x, y, w, h, TRUE);
#else
/* other platforms */
#endif
}
}

See near the bottom of this:

Note: If you want to control the position on the screen when creating a windowed surface, you may do so by setting the environment variables "SDL_VIDEO_CENTERED=center" or "SDL_VIDEO_WINDOW_POS=x,y". You can set them via SDL_putenv.


More info on SDL's enviornmental variables can be found here and here.
