Move SDL window in SDL 1.2

Question

I am using SDL 1.2 with FFmpeg on MAC. I am trying to build a video player using both FFmpeg and SDL. I am viewing my video on SDL_Surface. My player is working fine. Now my problem is, i want to move SDL window without dragging it from title bar. Is there any function/method in SDL 1.2 framework for moving SDL_Surface.

*i want to move SDL window*... with keyboard? Programatically? randomly? — Thomas Ayoub, May 05 '15 at 08:31

SDL 1.2 does not have an API for moving windows. SDL 2.0 has better support for multiple windows and window management in general.
See http://wiki.libsdl.org/SDL_SetWindowPosition

To do this with SDL 1.2, you'll need to use platform-specific calls using the window handle. You can get that with SDL_GetWMInfo().

If you just need to set the initial position of the window so it is centered, then try this before SDL_SetVideoMode():

SDL_putenv("SDL_VIDEO_WINDOW_POS=center");

The function you are looking for is:

void SDL_SetWindowPosition(SDL_Window* window,
                           int         x,
                           int         y)

Which set the position of the window for you.

this function is defined in SDL 2.0 but i am using SDL 1.2. Is there any other way for SDL 1.2 ? – Dev Sam May 06 '15 at 06:31
@DevSam do you've got something like `SetWindowPos` to use it like so : `SetWindowPos(pInfo.window, 0, r.left, r.top, 0, 0, SWP_NOMOVE | SWP_NOSIZE);` – Thomas Ayoub May 06 '15 at 08:11
