Header File

Syntax

SDL_Window* SDL_CreateWindowWithProperties(SDL_PropertiesID props);

Function Parameters

props

the properties to use

Return Value

Returns the window that was created or NULL on failure; call SDL_GetError() for more information.

Remarks

These are the supported properties:

SDL_PROP_WINDOW_CREATE_ALWAYS_ON_TOP_BOOLEAN: true if the window should be always on top
SDL_PROP_WINDOW_CREATE_BORDERLESS_BOOLEAN: true if the window has no window decoration
SDL_PROP_WINDOW_CREATE_EXTERNAL_GRAPHICS_CONTEXT_BOOLEAN: true if the window will be used with an externally managed graphics context.
SDL_PROP_WINDOW_CREATE_FOCUSABLE_BOOLEAN: true if the window should accept keyboard input (defaults true)
SDL_PROP_WINDOW_CREATE_FULLSCREEN_BOOLEAN: true if the window should start in fullscreen mode at desktop resolution
SDL_PROP_WINDOW_CREATE_HEIGHT_NUMBER: the height of the window
SDL_PROP_WINDOW_CREATE_HIDDEN_BOOLEAN: true if the window should start hidden
SDL_PROP_WINDOW_CREATE_HIGH_PIXEL_DENSITY_BOOLEAN: true if the window uses a high pixel density buffer if possible
SDL_PROP_WINDOW_CREATE_MAXIMIZED_BOOLEAN: true if the window should start maximized
SDL_PROP_WINDOW_CREATE_MENU_BOOLEAN: true if the window is a popup menu
SDL_PROP_WINDOW_CREATE_METAL_BOOLEAN: true if the window will be used with Metal rendering
SDL_PROP_WINDOW_CREATE_MINIMIZED_BOOLEAN: true if the window should start minimized
SDL_PROP_WINDOW_CREATE_MODAL_BOOLEAN: true if the window is modal to its parent
SDL_PROP_WINDOW_CREATE_MOUSE_GRABBED_BOOLEAN: true if the window starts with grabbed mouse focus
SDL_PROP_WINDOW_CREATE_OPENGL_BOOLEAN: true if the window will be used with OpenGL rendering
SDL_PROP_WINDOW_CREATE_PARENT_POINTER: an SDL_Window that will be the parent of this window, required for windows with the "toolip", "menu", and "modal" properties
SDL_PROP_WINDOW_CREATE_RESIZABLE_BOOLEAN: true if the window should be resizable
SDL_PROP_WINDOW_CREATE_TITLE_STRING: the title of the window, in UTF-8 encoding
SDL_PROP_WINDOW_CREATE_TRANSPARENT_BOOLEAN: true if the window show transparent in the areas with alpha of 0
SDL_PROP_WINDOW_CREATE_TOOLTIP_BOOLEAN: true if the window is a tooltip
SDL_PROP_WINDOW_CREATE_UTILITY_BOOLEAN: true if the window is a utility window, not showing in the task bar and window list
SDL_PROP_WINDOW_CREATE_VULKAN_BOOLEAN: true if the window will be used with Vulkan rendering
SDL_PROP_WINDOW_CREATE_WIDTH_NUMBER: the width of the window
SDL_PROP_WINDOW_CREATE_X_NUMBER: the x position of the window, or SDL_WINDOWPOS_CENTERED, defaults to SDL_WINDOWPOS_UNDEFINED. This is relative to the parent for windows with the "parent" property set.
SDL_PROP_WINDOW_CREATE_Y_NUMBER: the y position of the window, or SDL_WINDOWPOS_CENTERED, defaults to SDL_WINDOWPOS_UNDEFINED. This is relative to the parent for windows with the "parent" property set.

These are additional supported properties on macOS:

SDL_PROP_WINDOW_CREATE_COCOA_WINDOW_POINTER: the (__unsafe_unretained) NSWindow associated with the window, if you want to wrap an existing window.
SDL_PROP_WINDOW_CREATE_COCOA_VIEW_POINTER: the (__unsafe_unretained) NSView associated with the window, defaults to [window contentView]

These are additional supported properties on Wayland:

SDL_PROP_WINDOW_CREATE_WAYLAND_SCALE_TO_DISPLAY_BOOLEAN
- true if the window should use forced scaling designed to produce 1:1 pixel mapping if not flagged as being DPI-aware. This is intended to allow legacy applications to be displayed without desktop scaling being applied, and has issues with certain display configurations, as this forces the window to behave in a way that Wayland desktops were not designed to accommodate. Potential issues include, but are not limited to: rounding errors can result when odd window sizes/scales are used, the window may be unusably small, the window may jump in visible size at times, the window may appear to be larger than the desktop space, and possible loss of cursor precision can occur. New applications should be designed with proper DPI awareness and handling instead of enabling this.
SDL_PROP_WINDOW_CREATE_WAYLAND_SURFACE_ROLE_CUSTOM_BOOLEAN
- true if the application wants to use the Wayland surface for a custom role and does not want it attached to an XDG toplevel window. See README/wayland for more information on using custom surfaces.
SDL_PROP_WINDOW_CREATE_WAYLAND_CREATE_EGL_WINDOW_BOOLEAN
- true if the application wants an associated wl_egl_window object to be created, even if the window does not have the OpenGL property or flag set.
SDL_PROP_WINDOW_CREATE_WAYLAND_WL_SURFACE_POINTER
- the wl_surface associated with the window, if you want to wrap an existing window. See README/wayland for more information.

These are additional supported properties on Windows:

SDL_PROP_WINDOW_CREATE_WIN32_HWND_POINTER: the HWND associated with the window, if you want to wrap an existing window.
SDL_PROP_WINDOW_CREATE_WIN32_PIXEL_FORMAT_HWND_POINTER: optional, another window to share pixel format with, useful for OpenGL windows

These are additional supported properties with X11:

SDL_PROP_WINDOW_CREATE_X11_WINDOW_NUMBER: the X11 Window associated with the window, if you want to wrap an existing window.

The window is implicitly shown if the "hidden" property is not set.

Windows with the "tooltip" and "menu" properties are popup windows and have the behaviors and guidelines outlined in SDL_CreatePopupWindow().

Version

This function is available since SDL 3.0.0.
