A variable that forces X11 windows to create as a custom type.

Header File

Defined in SDL_hints.h




This is currently only used for X11 and ignored elsewhere.

During 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 or 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".

If not set or set to "", this hint is ignored. This hint must be set before the SDL_CreateWindow() call that it is intended to affect.

This hint is available since SDL 2.0.22.
