[MacRuby-devel] Dynamic refresh in a view - xcode 4 / MacRuby

[Laurent Sansonetti]

Just one minor detail, the NSTimer callback method accepts an argument (which is a reference to the NSTimer object). So it should be:

  def drawWord(sender)
    …
  end

If it works otherwise, then it's pure luck :)
