(This is the legacy documentation for SDL2, the previous stable version; SDL3 is the current stable version.)

SDL_Vulkan_GetDrawableSize

Get the size of the window's underlying drawable dimensions in pixels.

Header File

Defined in SDL_vulkan.h

Syntax

void SDL_Vulkan_GetDrawableSize(SDL_Window * window,
                                int *w, int *h);

Function Parameters

SDL_Window *	window	an SDL_Window for which the size is to be queried.
int *	w	Pointer to the variable to write the width to or NULL.
int *	h	Pointer to the variable to write the height to or NULL.

Remarks

This may differ from SDL_GetWindowSize() if we're rendering to a high-DPI drawable, i.e. the window was created with SDL_WINDOW_ALLOW_HIGHDPI on a platform with high-DPI support (Apple calls this "Retina"), and not disabled by the SDL_HINT_VIDEO_HIGHDPI_DISABLED hint.

Version

This function is available since SDL 2.0.6.
