SDL_MouseMotionEvent is a
member of the SDL_Event union
and is used when an event of type SDL_MOUSEMOTION is reported.
Simply put, a SDL_MOUSEMOTION type event occurs when a
user moves the mouse within the application window or when
SDL_WarpMouse is called. Both
the absolute (x and
y) and relative
(xrel and
yrel) coordinates
are reported along with the current button states (state). The button state can
be interpreted using the SDL_BUTTON macro (see SDL_GetMouseState).
If the cursor is hidden (SDL_ShowCursor(0)) and the input is grabbed
(SDL_WM_GrabInput(SDL_GRAB_ON)),
then the mouse will give relative motion events even when the
cursor reaches the edge fo the screen. This is currently only
implemented on Windows and Linux/Unix-a-likes.
