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.
