To be honest, for no special reason, it seemed the "natural choice" to
me :)
BTW, in my example I did frame.configure(width=...) in the <Configure>
event binding, which at a second glance I would replace with
canvas.itemconfigure (w, width=event.width-2...)
A real advantage of the window items vs. pack() might be that it is
probably easier to handle when there are multiple widgets placed in the
canvas.

You can avoid this with pack(pady=(1,0))
