SDL_JoyHatEvent

Joystick hat position change event structure (event.jhat.*)

Header File

Defined in [SDL_events.h](https://github.com/libsdl-org/SDL/blob/SDL2/include/SDL_events.h), but apps should _only_ `#include "SDL.h"`!

Syntax

typedef struct SDL_JoyHatEvent
{
    Uint32 type;        /**< ::SDL_JOYHATMOTION */
    Uint32 timestamp;   /**< In milliseconds, populated using SDL_GetTicks() */
    SDL_JoystickID which; /**< The joystick instance id */
    Uint8 hat;          /**< The joystick hat index */
    Uint8 value;        /**< The hat position value.
                         *   \sa ::SDL_HAT_LEFTUP ::SDL_HAT_UP ::SDL_HAT_RIGHTUP
                         *   \sa ::SDL_HAT_LEFT ::SDL_HAT_CENTERED ::SDL_HAT_RIGHT
                         *   \sa ::SDL_HAT_LEFTDOWN ::SDL_HAT_DOWN ::SDL_HAT_RIGHTDOWN
                         *
                         *   Note that zero means the POV is centered.
