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

       This struct is available since SDL 3.2.0.

Simple Directmedia Layer                           SDL 3.2.10                          SDL_PenMotionEvent(3type)

       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.
