flagsThe flags for the window, a mask of any of the following: SDL_WINDOW_FULLSCREEN, SDL_WINDOW_OPENGL, SDL_WINDOW_HIDDEN, SDL_WINDOW_BORDERLESS, SDL_WINDOW_RESIZABLE, SDL_WINDOW_MAXIMIZED, SDL_WINDOW_MINIMIZED, SDL_WINDOW_INPUT_GRABBED, SDL_WINDOW_ALLOW_HIGHDPI, SDL_WINDOW_VULKAN.
Returns
The created window, or NULL if window creation failed.

If the window is created with the SDL_WINDOW_ALLOW_HIGHDPI flag, its size in pixels may differ from its size in screen coordinates on platforms with high-DPI support (e.g. iOS and Mac OS X). Use SDL_GetWindowSize() to query the client area's size in screen coordinates, and SDL_GL_GetDrawableSize(), SDL_Vulkan_GetDrawableSize(), or SDL_GetRendererOutputSize() to query the drawable size in pixels.

If the window is created with any of the SDL_WINDOW_OPENGL or SDL_WINDOW_VULKAN flags, then the corresponding LoadLibrary function (SDL_GL_LoadLibrary or SDL_Vulkan_LoadLibrary) is called and the corresponding UnloadLibrary function is called by SDL_DestroyWindow().

If SDL_WINDOW_VULKAN is specified and there isn't a working Vulkan driver, SDL_CreateWindow() will fail because SDL_Vulkan_LoadLibrary() will fail.

Note
On non-Apple devices, SDL requires you to either not link to the Vulkan loader or link to a dynamic library version. This limitation may be removed in a future version of SDL.

◆ SDL_GetClosestDisplayMode()

SDL_DisplayMode* SDL_GetClosestDisplayMode ( int  displayIndex,

Get the closest match to the requested display mode.

Parameters
displayIndexThe index of display from which mode should be queried.
modeThe desired display mode
closestA pointer to a display mode to be filled in with the closest match of the available display modes.
Returns
The passed in value closest, or NULL if no matching video mode was available.

The available display modes are scanned, and closest is filled in with the closest mode matching the requested mode and returned. The mode format and refresh_rate default to the desktop mode if they are 0. The modes are scanned with size being first priority, format being second priority, and finally checking the refresh_rate. If all the available modes are too small, then NULL is returned.

Get the usable desktop area represented by a display, with the primary display located at 0,0.

This is the same area as SDL_GetDisplayBounds() reports, but with portions reserved by the system removed. For example, on Mac OS X, this subtracts the area occupied by the menu bar and dock.

Setting a window to be fullscreen generally bypasses these unusable areas, so these are good guidelines for the maximum space available to a non-fullscreen window.

◆ SDL_GL_GetDrawableSize()

void SDL_GL_GetDrawableSize ( SDL_Window window,
int *  w,

)

Get the size of a window's underlying drawable in pixels (for use with glViewport).

Parameters
windowWindow from which the drawable size should be queried
wPointer to variable for storing the width in pixels, may be NULL
hPointer to variable for storing the height in pixels, may be NULL

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.

◆ SDL_GL_GetSwapInterval()

int SDL_GL_GetSwapInterval ( void  )

Get the swap interval for the current OpenGL context.

Returns
0 if there is no vertical retrace synchronization, 1 if the buffer swap is synchronized with the vertical retrace, and -1 if late swaps happen immediately instead of waiting for the next retrace. If the system can't determine the swap interval, or there isn't a valid current context, this will return 0 as a safe default.

◆ SDL_GL_LoadLibrary()

int SDL_GL_LoadLibrary ( const char *  path)

Dynamically load an OpenGL library.

Parameters
pathThe platform dependent OpenGL library name, or NULL to open the default OpenGL library.
Returns
0 on success, or -1 if the library couldn't be loaded.

This should be done after initializing the video driver, but before creating any OpenGL windows. If no OpenGL library is loaded, the default library will be loaded upon creation of the first OpenGL window.

Note
If you do this, you need to retrieve all of the GL functions used in your program from the dynamic library using SDL_GL_GetProcAddress().

◆ SDL_SetWindowGammaRamp()

int SDL_SetWindowGammaRamp ( SDL_Window window,
const Uint16 red,
const Uint16 green,
const Uint16 blue 
)

Set the gamma ramp for a window.

Parameters
windowThe window for which the gamma ramp should be set.
redThe translation table for the red channel, or NULL.
greenThe translation table for the green channel, or NULL.
blueThe translation table for the blue channel, or NULL.
Returns
0 on success, or -1 if gamma ramps are unsupported.

Set the gamma translation table for the red, green, and blue channels of the video hardware. Each table is an array of 256 16-bit quantities, representing a mapping between the input and output for that channel. The input is the index into the array, and the output is the 16-bit gamma value at that index, scaled to the output color precision.

◆ SDL_SetWindowGrab()

void SDL_SetWindowGrab ( SDL_Window window,
SDL_bool  grabbed 
)

Set a window's input grab mode.

Parameters
windowThe window for which the input grab mode should be set.
grabbedThis is SDL_TRUE to grab input, and SDL_FALSE to release input.

If the caller enables a grab while another window is currently grabbed, the other window loses its grab in favor of the caller's window.

◆ SDL_SetWindowHitTest()

int SDL_SetWindowHitTest ( SDL_Window window,
SDL_HitTest  callback,
void callback_data 
)

Provide a callback that decides if a window region has special properties.

Normally windows are dragged and resized by decorations provided by the system window manager (a title bar, borders, etc), but for some apps, it makes sense to drag them from somewhere else inside the window itself; for example, one might have a borderless window that wants to be draggable from any part, or simulate its own title bar, etc.

This function lets the app provide a callback that designates pieces of a given window as special. This callback is run during event processing if we need to tell the OS to treat a region of the window specially; the use of this callback is known as "hit testing."

Mouse input may not be delivered to your application if it is within a special area; the OS will often apply that input to moving the window or resizing the window and not deliver it to the application.

Specifying NULL for a callback disables hit-testing. Hit-testing is disabled by default.

Platforms that don't support this functionality will return -1 unconditionally, even if you're attempting to disable hit-testing.

Your callback may fire at any time, and its firing does not indicate any specific behavior (for example, on Windows, this certainly might fire when the OS is deciding whether to drag your window, but it fires for lots of other reasons, too, some unrelated to anything you probably care about and when the mouse isn't actually at the location it is testing). Since this can fire at any time, you should try to keep your callback efficient, devoid of allocations, etc.

Parameters
windowThe window to set hit-testing on.
callbackThe callback to call when doing a hit-test.
callback_dataAn app-defined void pointer passed to the callback.
Returns
0 on success, -1 on error (including unsupported).

◆ SDL_SetWindowInputFocus()

int SDL_SetWindowInputFocus ( SDL_Window window)

Explicitly sets input focus to the window.

You almost certainly want SDL_RaiseWindow() instead of this function. Use this with caution, as you might give focus to a window that's completely obscured by other windows.

Parameters
windowThe window that should get the input focus
Returns
0 on success, or -1 otherwise.

Parameters
windowThe window of which to change the resizable state.
resizableSDL_TRUE to allow resizing, SDL_FALSE to disallow.
Note
You can't change the resizable state of a fullscreen window.

◆ SDL_SetWindowSize()

void SDL_SetWindowSize ( SDL_Window window,

Set the size of a window's client area.

Parameters
windowThe window to resize.
wThe width of the window, in screen coordinates. Must be >0.
hThe height of the window, in screen coordinates. Must be >0.
Note
Fullscreen windows automatically match the size of the display mode, and you should use SDL_SetWindowDisplayMode() to change their size.

The window size in screen coordinates may differ from the size in pixels, if the window was created with SDL_WINDOW_ALLOW_HIGHDPI on a platform with high-dpi support (e.g. iOS or OS X). Use SDL_GL_GetDrawableSize() or SDL_GetRendererOutputSize() to get the real client area size in pixels.

◆ SDL_Vulkan_CreateSurface()

SDL_bool SDL_Vulkan_CreateSurface ( SDL_Window window,
VkInstance  instance,
VkSurfaceKHR *  surface 
)

Create a Vulkan rendering surface for a window.

Parameters
[in]windowSDL_Window to which to attach the rendering surface.
[in]instancehandle to the Vulkan instance to use.
[out]surfacepointer to a VkSurfaceKHR handle to receive the handle of the newly created surface.
Returns
SDL_TRUE on success, SDL_FALSE on error.
VkInstance instance;
// create instance and window
// create the Vulkan surface
VkSurfaceKHR surface;
handle_error();
Note
window should have been created with the SDL_WINDOW_VULKAN flag.
instance should have been created with the extensions returned by SDL_Vulkan_CreateSurface() enabled.

◆ SDL_Vulkan_GetDrawableSize()

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

Get the size of a window's underlying drawable in pixels (for use with setting viewport, scissor & etc).

Parameters
windowSDL_Window from which the drawable size should be queried
wPointer to variable for storing the width in pixels, may be NULL
hPointer to variable for storing the height in pixels, may be NULL

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.

Note
On macOS high-DPI support must be enabled for an application by setting NSHighResolutionCapable to true in its Info.plist.

◆ SDL_Vulkan_LoadLibrary()

int SDL_Vulkan_LoadLibrary ( const char *  path)

Dynamically load a Vulkan loader library.

Parameters
[in]pathThe platform dependent Vulkan loader library name, or NULL.
Returns
0 on success, or -1 if the library couldn't be loaded.

If path is NULL SDL will use the value of the environment variable SDL_VULKAN_LIBRARY, if set, otherwise it loads the default Vulkan loader library.

This should be called after initializing the video driver, but before creating any Vulkan windows. If no Vulkan loader library is loaded, the default library will be loaded upon creation of the first Vulkan window.

Note
It is fairly common for Vulkan applications to link with libvulkan instead of explicitly loading it at run time. This will work with SDL provided the application links to a dynamic library and both it and SDL use the same search path.
If you specify a non-NULL path, an application should retrieve all of the Vulkan functions it uses from the dynamic library using SDL_Vulkan_GetVkGetInstanceProcAddr() unless you can guarantee path points to the same vulkan loader library the application linked to.
On Apple devices, if path is NULL, SDL will attempt to find the vkGetInstanceProcAddr address within all the mach-o images of the current process. This is because it is fairly common for Vulkan applications to link with libvulkan (and historically MoltenVK was provided as a static library). If it is not found then, on macOS, SDL will attempt to load vulkan.framework/vulkan, libvulkan.1.dylib, MoltenVK.framework/MoltenVK and libMoltenVK.dylib in that order. On iOS SDL will attempt to load libMoltenVK.dylib. Applications using a dynamic framework or .dylib must ensure it is included in its application bundle.
On non-Apple devices, application linking with a static libvulkan is not supported. Either do not link to the Vulkan loader or link to a dynamic library version.
This function will fail if there are no working Vulkan drivers installed.
