SDL_!MouseMotionEvent?- Mouse motion event structure
typedef struct{ Uint8 type; Uint8 state; Uint16 x, y; Sint16 xrel, yrel; } SDL_!MouseMotionEvent?;

state The current button state
x, y The X/Y coordinates of the mouse
xrel, yrel Relative motion in the X/Y direction
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.
