在SDL 1.2中移动SDL窗口

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.

Answer 1

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");

Answer 2

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.
