NAME
SDL_MouseMotionEvent - Mouse motion event structure
STRUCTURE DEFINITION
typedef struct{
Uint8 type;
Uint8 state;
Uint16 x, y;
Sint16 xrel, yrel;
} SDL_MouseMotionEvent;
STRUCTURE DATA
type SDL_MOUSEMOTION
state The current button state
x, y The X/Y coordinates of the mouse
xrel, yrel Relative motion in the X/Y direction
DESCRIPTION
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_GetMouseS-
tate).
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 mo-
tion events even when the cursor reaches the edge fo the screen. This
is currently only implemented on Windows and Linux/Unix-a-likes.
