PushEvent

[salviati]

cEvent() causes panic with panic: reflect.Value.UnsafeAddr of unaddressable value.. One can simply try pushing a UserEvent to get this.

This doesn't look as pretty, but at least it works:

func PushEvent(event Event) bool {
    var p cast
    switch ev := event.(type) {
        case ActiveEvent: p = cast(&ev)
        case KeyboardEvent: p = cast(&ev)
        case MouseMotionEvent: p = cast(&ev)
        case MouseButtonEvent: p = cast(&ev)
        case JoyAxisEvent: p = cast(&ev)
        case JoyBallEvent: p = cast(&ev)
        case JoyHatEvent: p = cast(&ev)
        case JoyButtonEvent: p = cast(&ev)
        case ResizeEvent: p = cast(&ev)
        case ExposeEvent: p = cast(&ev)
        case QuitEvent: p = cast(&ev)
        case UserEvent: p = cast(&ev)
        case SysWMEvent: p = cast(&ev)
        default: panic(fmt.Errorf("Unknown event type: %T", event))
    }
    ret := C.SDL_PushEvent((*C.SDL_Event)(p))
    return ret != 0
}

Found the problem. cEvent() is attempting to run UnsafeAddr() on a pointer. I'll send in a pull-request with a fix.

One other thing to note, however: It looks like you're attempting to run PushEvent() on a non-pointer. You need to run it on a pointer:

PushEvent(UserEvent{})

will panic, but

PushEvent(&UserEvent{})

will succeed, after the fix is implemented. I'll also add something to the godoc comment for PushEvent() that explicitly states that.

This is not compatible with the current event-handling though (which needs to be changed anyway: Issue 55).
