> Can anyone tell me how to 'move' an existing TckOval in Ruby Tk?

For example, 
------------------------------------------------------------
canvas = TkCanvas.new.pack

tag = TkcTag.new(canvas)

oval = TkcOval.new(canvas, [100,100], [150,150], :tags=>tag)
line = TkcLine.new(canvas, [100,100], [150,150], :tags=>tag)

oval.move(20, -15) # move 
line.move(20, -15) # move 

tag.move(30, 20) # move items with tag

oval.coords([50,100], [200,140]) # transform
line.coords([50,50], [100,50], [50,100], [200,140]) # transform
------------------------------------------------------------
