/me sighs remembering when he did that with good ol' Delphi

I've no experience of Tk, moreover I did not follow the thread from the
beginning, so apologies in advance.  Does anything prevent you to extend
the TkText object with a new setter method that also triggers refresh?

class TkText
  def my_value=(text)
    # set the text
    # trigger refresh
  end
end

Anyway, a noble purpose, especially for people (like me!) not too fond
of writing GUI code.  Let us (or the RAA) know about your results!
