help: menu item callback in TK

[lin li]

Hi,

I have the following problem and any help is greatly appreciated. 
I generated a menu using the data in a dynamically composed list. 
Since I do not know what will be in the list, I can only have all the 
command items in the menu to point to the same callback. Now 
from inside the callback, how can I find out which menu item is 
selected? To make it more interesting, the menu can have two or 
three levels of cascades.

I am running Python 1.5.2 with Tkinter on NT.

Thank you very much.
