SDL_TouchFingerEvent

Touch finger event structure (event.tfinger.*)

Header File

Defined in SDL_events.h

Syntax

typedef struct SDL_TouchFingerEvent
{
    Uint32 type;        /**< ::SDL_FINGERMOTION or ::SDL_FINGERDOWN or ::SDL_FINGERUP */
    Uint32 timestamp;   /**< In milliseconds, populated using SDL_GetTicks() */
    SDL_TouchID touchId; /**< The touch device id */
    SDL_FingerID fingerId;
    float x;            /**< Normalized in the range 0...1 */
    float y;            /**< Normalized in the range 0...1 */
    float dx;           /**< Normalized in the range -1...1 */
    float dy;           /**< Normalized in the range -1...1 */
    float pressure;     /**< Normalized in the range 0...1 */
    Uint32 windowID;    /**< The window underneath the finger, if any */
} SDL_TouchFingerEvent;
