Snipped code > canv.itemconfig(rect, width=width*progress/100) ## The width option of a rectangle item does not change the rectangles width, but changes the width of the rectangle perimiter line. You need to modify the coordinates of the rectangle item: canv.coords(rect, 0, 0, width*progress/100, height) Regards, John -- http://mail.python.org/mailman/listinfo/python-list
