# SDL\_PenMotionEvent(3type)

Pressure-sensitive pen motion event structure (event.pmotion.\*)

## NAME

SDL\_PenMotionEvent - Pressure-sensitive pen motion event structure (event.pmotion.\*)

## HEADER FILE

Defined in SDL3/SDL\_events.h

## SYNOPSIS

```
#include "SDL3/SDL.h"
```

**typedef struct SDL\_PenMotionEvent** **{**     **SDL\_EventType type; /\*\*\< SDL\_EVENT\_PEN\_MOTION \*/**     **Uint32 reserved;**     **Uint64 timestamp;   /\*\*\< In nanoseconds, populated using SDL\_GetTicksNS() \*/**     **SDL\_WindowID windowID; /\*\*\< The window with pen focus, if any \*/**     **SDL\_PenID which;        /\*\*\< The pen instance id \*/**     **SDL\_PenInputFlags pen\_state;   /\*\*\< Complete pen input state at time of event \*/**     **float x;                /\*\*\< X coordinate, relative to window \*/**     **float y;                /\*\*\< Y coordinate, relative to window \*/** **} SDL\_PenMotionEvent;**

## DESCRIPTION

Depending on the hardware, you may get motion events when the pen is not touching a tablet, for tracking a pen even when it isn't drawing. You should listen for  **SDL\_EVENT\_PEN\_DOWN**\
  and

**SDL\_EVENT\_PEN\_UP**\
  events, or check **pen\_state**& SDL\_PEN\_INPUT\_DOWN to decide if a pen is "drawing" when dealing with pen motion.

## AVAILABILITY

This struct is available since SDL 3.2.0.
