[ruby-talk:12806] Re: Tk Demo in Windows

OK, I took one of the short demos, label.rb, inserted require 'tk'at
the top and ran it. Got this message:

/cygdrive/c/ruby/lib/ruby/1.6/tk.rb:819:in `_invoke': unknown option
"-positionWindow" (RuntimeError)
	from /cygdrive/c/ruby/lib/ruby/1.6/tk.rb:819:in `_invoke'
	from /cygdrive/c/ruby/lib/ruby/1.6/tk.rb:559:in `tk_call'
	from /cygdrive/c/ruby/lib/ruby/1.6/tk.rb:2000:in `configure'

	from C:\ruby\samples\tk\demos\label.rb:18:in `new'
	from C:\ruby\samples\tk\demos\label.rb:18

The code creates a TopLevel with:

# demo toplevel widget 
$label_demo = TkToplevel.new {|w|
  title("Label Demonstration")
  iconname("label")
  positionWindow(w)
}

If I comment out the #positionWindow, it bombs on trying to read an
image. If I comment out the image button, then label.rb runs but never
opens a window.

I'm out of ideas. Someone who has a clue, please help out.

Thanks,

Ron
