# SDL_SetWindowResizable
Set the user-resizable state of a window.
## Header File
Defined in [SDL_video.h](https://github.com/libsdl-org/SDL/blob/SDL2/include/SDL_video.h)
## Syntax
```c
void SDL_SetWindowResizable(SDL_Window * window,
SDL_bool resizable);
```
## Function Parameters
| | | |
| -------------------------- | ------------- | --------------------------------------------------------------------------- |
| [SDL_Window](SDL_Window) * | **window** | the window of which to change the resizable state. |
| [SDL_bool](SDL_bool) | **resizable** | [SDL_TRUE](SDL_TRUE) to allow resizing, [SDL_FALSE](SDL_FALSE) to disallow. |
## Remarks
This will add or remove the window's
[`SDL_WINDOW_RESIZABLE`](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.
You can't change the resizable state of a fullscreen window.
## Version
This function is available since SDL 2.0.5.
