Subject: TkCanvas TkcPolygon state disability

Rubies:

Run this:

#!/usr/bin/env ruby

require "tk"

def main

        top = TkRoot.new

        canvas  = TkCanvas.new (top)

        canvas.grid 'row'=>0,  'column'=>0
                                    
        canvas.configure 'background' => '#888888',
                                         'width' => 200,
                                         'height' => 200 * 2 / 3

        shape = [30, 30, 30, 60, 60, 30 ] 

        poly1 = TkcPolygon.new(canvas, shape) { 
            fill 'green'
             outline 'white'
             disabledoutline ''
             width 3
             state 'normal'
             }
        poly2 = TkcPolygon.new(canvas, shape) { 
            fill 'red' 
             outline 'white'
             disabledoutline ''
             width 3
             state 'disabled'
            }
        poly2.move 60, 70
        
        top.bind ('KeyPress-Return') {
            poly1.configure 'state' => 'disabled'
            poly2.configure 'state' => 'normal'
            }

        Tk.mainloop

end

Under Ruby 1.6.6 and its Tk, both triangles come up with white outlines. 
The disabled emphasis does not display. If you tap Return both triangles 
still appear enabled.

My work-around configures the outline itself - either 'white' or ''. It 
would be nice if these advanced features worked, but I'm unaware if they 
work in Tkinter or Tcl/Tk either.
