Tkinter and simulated transparency

[Stephane Conversy]

Hi.

I have a top level window with an embeded canvas
To simulate transparency, I want to grab the image in the root window
at the place where the toplevel will be displayed, and put the
image in the canvas.

Is it possible to do that with Tkinter (grab a part of the root window)
?

BTW, what is the purpose of the non-refresh behavior of the toplevel
window ? If I put a canvas into it and then I pack() it, it's background

is displayed (as for the other widgets)..

Thanks.
