Hi All,
I’m new to the list, and searching the archives has
proven a little troublesome… my questoin:
I want to be able to place the window that appears in
an exact position… is this possible? when I do the
following:
screen = SDL_SetVideoMode(320, 240, 8,
SDL_SWSURFACE|SDL_ANYFORMAT|SDL_NOFRAME);
it creates a window and displays it on the screen…
I’d like to force that window to be in a certain x-y
position on the screen…
Thanks,
Michael__________________________________________________

Hello!
I’d like to force that window to be in a certain x-y
position on the screen…
If you are using ms windows, have a look at the following code.
(How long do i have to pray until this goes into the FAQ? 
)

#include “SDL_syswm.h”
static void SDL_center_window(SDL_Surface *screen)

int x, y;
int w, h;
#ifdef unix
if ( info.subsystem == SDL_SYSWM_X11 ) {
info.info.x11.lock_func();
w = DisplayWidth(info.info.x11.display,
DefaultScreen(info.info.x11.display));
h = DisplayHeight(info.info.x11.display,
DefaultScreen(info.info.x11.display));

y = (h - screen->h)/2;
XMoveWindow(info.info.x11.display, info.info.x11.wmwindow, x,
y);
info.info.x11.unlock_func();
}
#elif defined(WIN32)

‘#warning’ isn’t standard C, although some compilers accept it

This was copied from the FAQ, as well as the unix part.
