Timestamps always 0 in MultiGestureEvents from library

SDL Development

I am porting my apps to SDL3. I am using SDL_gesture.h from GitHub - libsdl-org/SDL_gesture: SDL2's gesture API split out into a single-header library.. All the events I am receiving from the library have timestamp == 0. What am I doing wrong?

I’m calling GestureInit() right after SDL_Init().

  if (!SDL_Init(SDL_INIT_VIDEO | SDL_INIT_EVENTS)) {
      fprintf(stderr, "%s: SDL video initialization failed: %s\n",
              theApp->name(), SDL_GetError());
      return 1;
  }
  Gesture_Init();

In the event handler

        Gesture_MultiGestureEvent& mgesture = *(Gesture_MultiGestureEvent *)event;
#if LOG_GESTURE_EVENTS
        SDL_Log("MG: x = %f, y = %f, dAng = %f (%f), dR = %f, numFingers = %i, timestamp = %i",
           mgesture.x,
           mgesture.y,
           mgesture.dTheta * 180.0 / M_PI,
           mgesture.dTheta,
           mgesture.dDist,
           mgesture.numFingers,
           mgesture.timestamp);
#endif

The code in SDL_gesture.h that generates the event sets timestamp = 0. Presumably it expects SDL_PushEvent((SDL_Event*)&mgesture); to add the timestamp. Why would it not be adding a timestamp?

The events structures declared in SDL_gesture.h were incompatible with SDL3 events. See SDL_gesture.h is incompatible with SDL 3 so timestamps are never set. · Issue #12 · libsdl-org/SDL_gesture · GitHub. They have now been fixed.
