Function Documentation

◆ SDL_CreateWindow()

DECLSPEC SDL_Window* SDLCALL SDL_CreateWindow	(	const char *	title,
		int	x,
		int	y,
		int	w,
		int	h,
		Uint32	flags
	)

Create a window with the specified position, dimensions, and flags.

Parameters

title	The title of the window, in UTF-8 encoding.
x	The x position of the window, SDL_WINDOWPOS_CENTERED, or SDL_WINDOWPOS_UNDEFINED.
y	The y position of the window, SDL_WINDOWPOS_CENTERED, or SDL_WINDOWPOS_UNDEFINED.
w	The width of the window, in screen coordinates.
h	The height of the window, in screen coordinates.
flags	The 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.

See also: SDL_DestroyWindow(); SDL_GL_LoadLibrary(); SDL_Vulkan_LoadLibrary()

◆ SDL_CreateWindowFrom()

DECLSPEC SDL_Window* SDLCALL SDL_CreateWindowFrom ( const void * data )

Create an SDL window from an existing native window.

Parameters

data	A pointer to driver-dependent window creation data

Returns: The created window, or NULL if window creation failed.

See also: SDL_DestroyWindow()

◆ SDL_DestroyWindow()

DECLSPEC void SDLCALL SDL_DestroyWindow ( SDL_Window * window )

Destroy a window.

◆ SDL_DisableScreenSaver()

DECLSPEC void SDLCALL SDL_DisableScreenSaver ( void )

	)

Get the closest match to the requested display mode.

Parameters

displayIndex	The index of display from which mode should be queried.
mode	The desired display mode
closest	A 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.

See also: SDL_GetNumDisplayModes(); SDL_GetDisplayMode()

		SDL_DisplayMode *	mode
	)

Fill in information about the current display mode.

Returns: The name of the current video driver or NULL if no driver has been initialized

See also: SDL_GetNumVideoDrivers(); SDL_GetVideoDriver()

◆ SDL_GetDesktopDisplayMode()

DECLSPEC int SDLCALL SDL_GetDesktopDisplayMode	(	int	displayIndex,
		SDL_DisplayMode *	mode
	)

Fill in information about the desktop display mode.

◆ SDL_GetDisplayBounds()

DECLSPEC int SDLCALL SDL_GetDisplayBounds	(	int	displayIndex,
		SDL_Rect *	rect
	)

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

See also: SDL_GetNumVideoDisplays()

◆ SDL_GetDisplayDPI()

DECLSPEC int SDLCALL SDL_GetDisplayDPI	(	int	displayIndex,
		float *	ddpi,
		float *	hdpi,
		float *	vdpi
	)

Get the dots/pixels-per-inch for a display.

Note: Diagonal, horizontal and vertical DPI can all be optionally returned if the parameter is non-NULL.

Returns: 0 on success, or -1 if no DPI information is available or the index is out of range.

See also: SDL_GetNumVideoDisplays()

◆ SDL_GetDisplayMode()

DECLSPEC int SDLCALL SDL_GetDisplayMode	(	int	displayIndex,
		int	modeIndex,
		SDL_DisplayMode *	mode
	)

Fill in information about a specific display mode.

Note

The display modes are sorted in this priority:

See also: SDL_GetNumVideoDisplays()

◆ SDL_GetDisplayUsableBounds()

DECLSPEC int SDLCALL SDL_GetDisplayUsableBounds	(	int	displayIndex,
		SDL_Rect *	rect
	)

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.

Returns: 0 on success, or -1 if the index is out of range.

See also: SDL_GetDisplayBounds(); SDL_GetNumVideoDisplays()

◆ SDL_GetGrabbedWindow()

DECLSPEC SDL_Window* SDLCALL SDL_GetGrabbedWindow ( void )

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.

See also: SDL_GL_SetSwapInterval()

◆ SDL_GL_LoadLibrary()

DECLSPEC int SDLCALL SDL_GL_LoadLibrary ( const char * path )

Dynamically load an OpenGL library.

Parameters

path	The 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().

Set the swap interval for the current OpenGL context.

Parameters

interval 0 for immediate updates, 1 for updates synchronized with the vertical retrace. If the system supports it, you may specify -1 to allow late swaps to happen immediately instead of waiting for the next retrace.

Returns: 0 on success, or -1 if setting the swap interval is not supported.

See also: SDL_GL_GetSwapInterval()

◆ SDL_GL_SwapWindow()

DECLSPEC void SDLCALL SDL_GL_SwapWindow ( SDL_Window * window )

Swap the OpenGL buffers for a window, if double-buffering is supported.

◆ SDL_SetWindowBordered()

DECLSPEC void SDLCALL SDL_SetWindowBordered	(	SDL_Window *	window,
		SDL_bool	bordered
	)

Set the border state of a window.

This will add or remove the window's SDL_WINDOW_BORDERLESS flag and add or remove the border from the actual window. This is a no-op if the window's border already matches the requested state.

Parameters

window	The window of which to change the border state.
bordered	SDL_FALSE to remove border, SDL_TRUE to add border.

Note: You can't change the border state of a fullscreen window.

window	The window for which the display mode should be set.
mode	The mode to use, or NULL for the default mode.

Returns: 0 on success, or -1 if setting the display mode failed.

◆ SDL_SetWindowFullscreen()

DECLSPEC int SDLCALL SDL_SetWindowFullscreen	(	SDL_Window *	window,
		Uint32	flags
	)

Set a window's fullscreen state.

Returns: 0 on success, or -1 if setting the display mode failed.

◆ SDL_SetWindowGammaRamp()

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

Set the gamma ramp for a window.

Parameters

window	The window for which the gamma ramp should be set.
red	The translation table for the red channel, or NULL.
green	The translation table for the green channel, or NULL.
blue	The 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()

DECLSPEC void SDLCALL SDL_SetWindowGrab	(	SDL_Window *	window,
		SDL_bool	grabbed
	)

Set a window's input grab mode.

Parameters

window	The window for which the input grab mode should be set.
grabbed	This 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.

See also: SDL_GetWindowGrab()

◆ SDL_SetWindowHitTest()

DECLSPEC int SDLCALL 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

window	The window to set hit-testing on.
callback	The callback to call when doing a hit-test.
callback_data	An app-defined void pointer passed to the callback.

Returns: 0 on success, -1 on error (including unsupported).

◆ SDL_SetWindowIcon()

DECLSPEC void SDLCALL SDL_SetWindowIcon	(	SDL_Window *	window,
		SDL_Surface *	icon
	)

Set the icon for a window.

Parameters

window	The window for which the icon should be set.
icon	The icon for the window.

◆ SDL_SetWindowInputFocus()

DECLSPEC int SDLCALL 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

window The window that should get the input focus

Returns: 0 on success, or -1 otherwise.

See also: SDL_RaiseWindow()

◆ SDL_SetWindowMaximumSize()

DECLSPEC void SDLCALL SDL_SetWindowMaximumSize	(	SDL_Window *	window,
		int	max_w,
		int	max_h
	)

Set the maximum size of a window's client area.

Parameters

window	The window to set a new maximum size.
max_w	The maximum width of the window, must be >0
max_h	The maximum height of the window, must be >0

Note: You can't change the maximum size of a fullscreen window, it automatically matches the size of the display mode.

See also: SDL_GetWindowMaximumSize(); SDL_SetWindowMinimumSize()

◆ SDL_SetWindowMinimumSize()

DECLSPEC void SDLCALL SDL_SetWindowMinimumSize	(	SDL_Window *	window,
		int	min_w,
		int	min_h
	)

Set the minimum size of a window's client area.

Parameters

window	The window to set a new minimum size.
min_w	The minimum width of the window, must be >0
min_h	The minimum height of the window, must be >0

Note: You can't change the minimum size of a fullscreen window, it automatically matches the size of the display mode.

See also: SDL_GetWindowMinimumSize(); SDL_SetWindowMaximumSize()

◆ SDL_SetWindowModalFor()

DECLSPEC int SDLCALL SDL_SetWindowModalFor	(	SDL_Window *	modal_window,
		SDL_Window *	parent_window
	)

Sets the window as a modal for another window (TODO: reconsider this function and/or its name)

Parameters

modal_window	The window that should be modal
parent_window	The parent window

Returns: 0 on success, or -1 otherwise.

◆ SDL_SetWindowOpacity()

DECLSPEC int SDLCALL SDL_SetWindowOpacity	(	SDL_Window *	window,
		float	opacity
	)

Set the opacity for a window.

Parameters

window	The window which will be made transparent or opaque
opacity	Opacity (0.0f - transparent, 1.0f - opaque) This will be clamped internally between 0.0f and 1.0f.

Returns: 0 on success, or -1 if setting the opacity isn't supported.

See also: SDL_GetWindowOpacity()

◆ SDL_SetWindowPosition()

DECLSPEC void SDLCALL SDL_SetWindowPosition	(	SDL_Window *	window,
		int	x,
		int	y
	)

Set the position of a window.

Parameters

window	The window to reposition.
x	The x coordinate of the window in screen coordinates, or SDL_WINDOWPOS_CENTERED or SDL_WINDOWPOS_UNDEFINED.
y	The y coordinate of the window in screen coordinates, or SDL_WINDOWPOS_CENTERED or SDL_WINDOWPOS_UNDEFINED.

Note: The window coordinate origin is the upper left of the display.

See also: SDL_GetWindowPosition()

◆ SDL_SetWindowResizable()

DECLSPEC void SDLCALL SDL_SetWindowResizable	(	SDL_Window *	window,
		SDL_bool	resizable
	)

Set the user-resizable state of a window.

This will add or remove the window's SDL_WINDOW_RESIZABLE flag and allow/disallow user resizing of the window. This is a no-op if the window's resizable state already matches the requested state.

Parameters

window	The window of which to change the resizable state.
resizable	SDL_TRUE to allow resizing, SDL_FALSE to disallow.

Note: You can't change the resizable state of a fullscreen window.

See also: SDL_GetWindowFlags()

◆ SDL_SetWindowSize()

DECLSPEC void SDLCALL SDL_SetWindowSize	(	SDL_Window *	window,
		int	w,
		int	h
	)

Set the size of a window's client area.

Parameters

window	The window to resize.
w	The width of the window, in screen coordinates. Must be >0.
h	The 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.

See also: SDL_GetWindowSize(); SDL_SetWindowDisplayMode()

◆ SDL_SetWindowTitle()

DECLSPEC void SDLCALL SDL_SetWindowTitle	(	SDL_Window *	window,
		const char *	title
	)

Set the title of a window, in UTF-8 format.

See also: SDL_GetWindowTitle()

◆ SDL_ShowWindow()

DECLSPEC void SDLCALL SDL_ShowWindow ( SDL_Window * window )

Show a window.

See also: SDL_HideWindow()

◆ SDL_UpdateWindowSurface()

DECLSPEC int SDLCALL SDL_UpdateWindowSurface ( SDL_Window * window )
