Fill a rectangle on the current rendering target with the drawing color.

Header File

Defined in SDL_render.h


int SDL_RenderFillRect(SDL_Renderer * renderer,
                       const SDL_Rect * rect);

Function Parameters

renderer the rendering context
rect the SDL_Rect structure representing the rectangle to fill, or NULL for the entire rendering target

Return Value

Returns 0 on success or a negative error code on failure; call SDL_GetError() for more information.


The current drawing color is set by SDL_SetRenderDrawColor(), and the color's alpha value is ignored unless blending is enabled with the appropriate call to SDL_SetRenderDrawBlendMode().
