Yes, you can use SDL_GetWMInfo().

Hi Mason, Thanks for your prompt reply… so if I am using Linux, will
there be a way to find out the XServer assigned window ID from the
window ID SDL uses internally?

Hi Sam, Thanks for your response. I tried this code segment within
test/testnativex11.c :

Window window = 0;
SDL_SysWMinfo info;

dpy = XOpenDisplay(NULL);
if (dpy) {
window =
XCreateSimpleWindow(dpy, DefaultRootWindow(dpy), 0, 0, w, h, 0, 0,
0);
XMapRaised(dpy, window);
XSync(dpy, False);

   SDL_GetWMInfo(&info);

…

I get:

(gdb) print info
$2 = {version = {major = 72 ‘H’, minor = 29 ‘\035’, patch = 64 ‘@’},
subsystem = SDL_SYSWM_X11, info = {x11 = { display = 0x7fc4246b8592,
window = 0, lock_func = 0x21f0850, unlock_func = 0x7fc42447d4fa,
fswindow = 4201680, wmwindow = 1}}}

xwininfo gives 0x2400001

Any idea?

Thanks

Did you check the return value? You need to set the version in the
info structure before you pass it in.On Fri, Oct 16, 2009 at 7:57 AM, Ratin wrote:
