  proc updateEvents() =
    while pollEvent(stEvent):
      case stEvent.kind
      of QuitEvent: bRunning = false
      of KEY_DOWN:
        #var key = cast[KeyboardEventPtr](addr stEvent) #error key can't use, (key.keysym.sym == k_escape) is invalid
        #if stEvent.key.KeySym.sym == K_ESCAPE: #error
          #bRunning = false
      else:
        discard

  I don't know how to use keyevent, Who can tell me, I think nim sdl2 must have more examples, Because it's not same the sdl2 c lib.

  Ok, I found it, But I still feel it trouble, Because haven't example and not same with sdl2.

  #it's ok
  proc updateEvents() =
    while pollEvent(stEvent):
      case stEvent.kind
      of QuitEvent: bRunning = false
      of KEY_DOWN:
        let key = stEvent.key()
        echo key.type.name
        case key.keySym.sym
        of K_ESCAPE: bRunning = false
        else: discard
      else:
        discard
  Run

  #I can't find key proc for Event.
  Event* = object
      ...
  Run
