###### (This is the documentation for SDL3, which is under heavy development and the API is changing! [SDL2](https://wiki.libsdl.org/SDL2/) is the current stable version!)
# SDL_MouseMotionEvent

Mouse motion event structure (event.motion.*)

## Header File

Defined in [SDL_events.h](https://github.com/libsdl-org/SDL/blob/main/include/SDL3/SDL_events.h), but apps should use `#include <SDL3/SDL.h>`

## Syntax

```c
typedef struct SDL_MouseMotionEvent
{
    SDL_EventType type; /**< ::SDL_EVENT_MOUSE_MOTION */
    Uint32 reserved;
    Uint64 timestamp;   /**< In nanoseconds, populated using SDL_GetTicksNS() */
    SDL_WindowID windowID; /**< The window with mouse focus, if any */
    SDL_MouseID which;  /**< The mouse instance id, SDL_TOUCH_MOUSEID, or SDL_PEN_MOUSEID */
    Uint32 state;       /**< The current button state */
    float x;            /**< X coordinate, relative to window */
    float y;            /**< Y coordinate, relative to window */
    float xrel;         /**< The relative motion in the X direction */
    float yrel;         /**< The relative motion in the Y direction */
} SDL_MouseMotionEvent;
```

## Version

This struct is available since SDL 3.0.0.
