Please can you help me with:
How to move window with SDL?

I can only speak from Windows experience, but there is no easy way to
move or position the window from within your code.

I tried this with no luck, but it was a quick test, so I might not
have filled everything out correctly for the struct/flags.

Tankko is not correct (I think.) It should be very easy to do on
windows. Observe:

#ifdef WIN32
/* Declare our “system window manager info” structure for retrieving
window manger system information, and a window handle */
HWND hwnd;
SDL_SysWMInfo info;

/* The info structure requires us to tell the runtime environment what
version of SDL we’re compiling with before we can SDL_GetWMInfo, so we
use a preprocessor macro, which will fill out info.version with
constants defined at build-time. I assume this is because the info
structure changes from version to version (can anyone back me up on
this?) */
SDL_VERSION(&info.version);
if (SDL_GetWMInfo(&info))
{
hwnd = info->window;
SetWindowPos(hwnd, x, y, width, height, FLAGS);
}
#endif/WIN32/

Rohit, you may have to set some FLAGS. For more information on those,
read the MSDN documentation for this function:

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/winui/
winui/windowsuserinterface/windowing/windows/windowreference/
windowfunctions/setwindowpos.asp

There is a possibility that this function isn’t known to work, and that
Tankko is way ahead of me. I haven’t personally done this, but I’ve had
extensive experience with Windows API programming, and I just dredged
up the rest by taking a brief look at the SDL source code.

Let me know if it works Rohit.

I tried to do it on Linux with:

int x = 0, y = 0;

SDL_SysWMinfo info;
SDL_VERSION(&info.version);

if (SDL_GetWMInfo(&info) > 0 ) {
if (info.subsystem == SDL_SYSWM_X11) {
info.info.x11.lock_func();
XMoveWindow(info.info.x11.display, info.info.x11.window, x, y);
info.info.x11.unlock_func();
}
}

But it moved Widget within Windows instead of moving Windows.

I tried to get parent Windows, but was not able to find a suitable
function to do that.

Regards,
Rohit Singh.

Try XQueryTree().

Following works:

SDL_SysWMinfo info;
Window root;
Window parent;
Window *children;
unsigned int children_count;
SDL_VERSION(&info.version);

if (SDL_GetWMInfo(&info) > 0 ) {
	if (info.subsystem == SDL_SYSWM_X11) {
		XQueryTree(	info.info.x11.display,
				info.info.x11.window,
				&root,
				&parent,
				&children,
				&children_count);
		info.info.x11.lock_func();
		XMoveWindow(	info.info.x11.display,
				parent,
				x,
				y);
		info.info.x11.unlock_func();
		if( children ) XFree(children);
	}
}
