Pressure-sensitive pen touched event structure (event.ptouch.*)

Header File

Defined in <SDL3/SDL_events.h>

Syntax

typedef struct SDL_PenTouchEvent
{
    SDL_EventType type;     /**< SDL_EVENT_PEN_DOWN or SDL_EVENT_PEN_UP */
    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 */
    bool eraser;        /**< true if eraser end is used (not all pens support this). */
    bool down;          /**< true if the pen is touching or false if the pen is lifted off */
} SDL_PenTouchEvent;

Remarks

These events come when a pen touches a surface (a tablet, etc), or lifts off from one.

Version

This struct is available since SDL 3.2.0.
