Description Daniel Gibson 2013-08-31 23:35:42 UTC 
When I have a window on my second (right) screen, the position I get from SDL_GetWindowPosition() is something like (2151, 276), as I would expect - my first (left) screen has a resolution of 1920x1200, so the screen right of it should start with x=1920.

SDL_GetWindowPosition however always returns (0,0) as Window position, which is also quite obvious from the implementation:
"if (window->flags & SDL_WINDOW_FULLSCREEN)" it just sets x and y to 0, because
"/* Fullscreen windows are always at their display's origin */"

This is of course inconsistent: In windowed mode the function returns a global (across all displays) coordinate, but in fullscreen mode the coordinate on the display it's on.. I guess this is a SDL1.2 leftover?

SDL_Window.x and .y contained the expected values (1920, 0), by the way, so at least on my platform (Linux/X11/xrandr) always returning those would be correct.

By the way, SDL_GetWindowBounds(SDL_Window*, SDL_Rect*) that works analogous to SDL_GetDisplayBounds() would be nice :)

This should have been "In fullscreen mode SDL_GetWindowPosition() however always returns (0,0) as Window position, ..."

This should be fixed with this commit: https://hg.libsdl.org/SDL/rev/cfeb59daba69
