SDL_PenDeviceType

An enum that describes the type of a pen device.

Header File

Defined in <SDL3/SDL_pen.h>

Syntax

typedef enum SDL_PenDeviceType
{
    SDL_PEN_DEVICE_TYPE_INVALID = -1, /**< Not a valid pen device. */
    SDL_PEN_DEVICE_TYPE_UNKNOWN,      /**< Don't know specifics of this pen. */
    SDL_PEN_DEVICE_TYPE_DIRECT,       /**< Pen touches display. */
    SDL_PEN_DEVICE_TYPE_INDIRECT      /**< Pen touches something that isn't the display. */
} SDL_PenDeviceType;

Remarks

A "direct" device is a pen that touches a graphic display (like an Apple Pencil on an iPad's screen). "Indirect" devices touch an external tablet surface that is connected to the machine but is not a display (like a lower-end Wacom tablet connected over USB).

Apps may use this information to decide if they should draw a cursor; if the pen is touching the screen directly, a cursor doesn't make sense and can be in the way, but becomes necessary for indirect devices to know where on the display they are interacting.

Version

This enum is available since SDL 3.4.0.
