Function SDL_CreateWindowWithProperties

pub unsafe extern "C" fn SDL_CreateWindowWithProperties(
    props: u32,
) -> *mut SDL_Window

Available on crate feature dep_sdl3 only.

Create a window with the specified properties.

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 “tooltip”, “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 “tooltip” or “menu” 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 “tooltip” or “menu” 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_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 and attached to the window, even if the window does not have the OpenGL property or SDL_WINDOW_OPENGL 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().

If this window is being created to be used with an [SDL_Renderer], you should not add a graphics API specific property (SDL_PROP_WINDOW_CREATE_OPENGL_BOOLEAN, etc), as SDL will handle that internally when it chooses a renderer. However, SDL might need to recreate your window at that point, which may cause the window to appear briefly, and then flicker as it is recreated. The correct approach to this is to create the window with the SDL_PROP_WINDOW_CREATE_HIDDEN_BOOLEAN property set to true, then create the renderer, then show the window with SDL_ShowWindow().

Parameters

• props: the properties to use.

Return value

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

Thread safety

This function should only be called on the main thread.

Availability

This function is available since SDL 3.2.0.
