Subject: Re: how to use Ruby / Tk to display a text message status bo

If however, you don't want a separate reporting thread, this is it:


require 'tk'

tk = TkRoot.new
text = TkText.new(tk, 'width'=>80, "height" => 60).pack()

#text = TkText.new(Tk.root).pack

i = 0
n = 100000

Tk.root.protocol(:WM_DELETE_WINDOW){
  if Tk.messageBox(:type=>'okcancel', :message=>'Really exit? ') == 'ok'
    printf "Bye ...\n"
    exit
  else
    # ignore
  end
}

evloop = Thread.new{ Tk.mainloop }
while (1)

  i += 1
  if i % n == 0
    text.value = <<EOS
This is GUI #{(i / n)}
Time is #{Time.now.strftime("%Y-%m-%d %I:%M:%S")}
EOS

    printf "This is command line #{i / n} "
  end
end
