sdlSetWindowMouseRect function

int sdlSetWindowMouseRect(
  1. Pointer<SdlWindow> window,
  2. Pointer<SdlRect> rect
)

Confines the cursor to the specified area of a window.

Note that this does NOT grab the cursor, it only defines the area a cursor is restricted to when the window has mouse focus.

\param window The window that will be associated with the barrier. \param rect A rectangle area in window-relative coordinates. If NULL the barrier for the specified window will be destroyed. \returns 0 on success or a negative error code on failure; call SDL_GetError() for more information.

\since This function is available since SDL 2.0.18.
