Function SDL_SetWindowRelativeMouseMode

pub unsafe extern "C" fn SDL_SetWindowRelativeMouseMode(
    window: *mut SDL_Window,
    enabled: bool,
) -> bool
Available on crate feature dep_sdl3 only.
Expand description

Set relative mouse mode for a window.

While the window has focus and relative mouse mode is enabled, the cursor is hidden, the mouse position is constrained to the window, and SDL will report continuous relative mouse motion even if the mouse is at the edge of the window.

If you’d like to keep the mouse position fixed while in relative mode you can use SDL_SetWindowMouseRect(). If you’d like the cursor to be at a specific location when relative mode ends, you should use SDL_WarpMouseInWindow() before disabling relative mode.

This function will flush any pending mouse motion for this window.

§Parameters

  • window: the window to change.
  • enabled: true to enable relative mode, false to disable.

§Return value

Returns true on success or false 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.
