###### (This is the documentation for SDL3, which is the current stable version. [SDL2](https://wiki.libsdl.org/SDL2/) was the previous version!) # SDL_HINT_X11_WINDOW_TYPE A variable specifying the type of an X11 window. ## Header File Defined in [](https://github.com/libsdl-org/SDL/blob/main/include/SDL3/SDL_hints.h) ## Syntax ```c #define SDL_HINT_X11_WINDOW_TYPE "SDL_X11_WINDOW_TYPE" ``` ## Remarks During [SDL_CreateWindow](SDL_CreateWindow), SDL uses the _NET_WM_WINDOW_TYPE X11 property to report to the window manager the type of window it wants to create. This might be set to various things if [SDL_WINDOW_TOOLTIP](SDL_WINDOW_TOOLTIP) or [SDL_WINDOW_POPUP_MENU](SDL_WINDOW_POPUP_MENU), etc, were specified. For "normal" windows that haven't set a specific type, this hint can be used to specify a custom type. For example, a dock window might set this to "_NET_WM_WINDOW_TYPE_DOCK". This hint should be set before creating a window. ## Version This hint is available since SDL 3.1.3. ---- [CategoryAPI](CategoryAPI), [CategoryAPIMacro](CategoryAPIMacro), [CategoryHints](CategoryHints)
