SDL_MouseMotionEvent

Mouse motion event structure (event.motion.*)

Header File

Defined in [SDL_events.h](https://github.com/libsdl-org/SDL/blob/SDL2/include/SDL_events.h), but apps should _only_ `#include "SDL.h"`!

Syntax

typedef struct SDL_MouseMotionEvent
{
    Uint32 type;        /**< ::SDL_MOUSEMOTION */
    Uint32 timestamp;   /**< In milliseconds, populated using SDL_GetTicks() */
    Uint32 windowID;    /**< The window with mouse focus, if any */
    Uint32 which;       /**< The mouse instance id, or SDL_TOUCH_MOUSEID */
    Uint32 state;       /**< The current button state */
    Sint32 x;           /**< X coordinate, relative to window */
    Sint32 y;           /**< Y coordinate, relative to window */
    Sint32 xrel;        /**< The relative motion in the X direction */
    Sint32 yrel;        /**< The relative motion in the Y direction */
} SDL_MouseMotionEvent;
