Detailed Description

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

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.

Since
This struct is available since SDL 3.0.0.
