Moving windows

SDL Development

Hi all,

Is there a function that lets you move an SDL window?

To move a surface just use variable SDL_Rect position in an SDL_BlitSuface() like this :

SDL_Rect rect;
rect.x = new_x_position;
rect.y = new_y_position;
this SDL_Rect structure define positions and width/height of surface

then call SDL_BlitSurface()

SDL_BlitSurface(surface_to_move, NULL, screen_surface, &rect);
SDL_UpdateRect(screen_surface); //or can be SDL_Flip()

Then in your main loop you can affect you SDL_Rect to any coordinates (can be mouse cursor, see SDL_MOUSEMOTION event to get cursor positions). Important is to blit each mouvement change with new rect positions.

Carlos I think he was refering to a window, not a
surface. I don’t know the answer, but I would expect
if it can be done that it is system specific.

Yeah I was referring to windows and not surfaces. Ideally, I’d like a
cross-platform solution. Any plans for a move window function in SDL 1.3 or
2.0?
