Subject: ruby tk drawing a line

I have a question concerning ruby/tk and drawing lines on a canvas.
I tried to convert from a tcl program. 
Everything works fine except that the line when its thickness is large 
appears to be a series of short line segments rather than a solid line.

I have binded the "1" mouse button to start the line with the following

canvas.bind( '1', proc { |e| 
			     
                             $startx = e.x
                             $starty = e.y
                             
                             })

and the motion of the mouse

canvas.bind('B1-Motion', proc { |e| 
      $endx = e.x
      $endy = e.y
                        
      $a  = TkcLine.new(canvas, $startx, $starty, $endx, $endy)
      $a.width option.value
      $a.fill "#{color}"
      })

Can anyone see why this does not give me a solid line
