Calling update_idletasks() from within this method before quering diplay data
should do the trick.
The only way I can think of to do this without using the

I think the tkFont module has what you need:
>>> from Tkinter import *
>>> l=Label(text='hi')
>>> l.pack()
>>> import tkFont
>>> f=tkFont.Font(family='helvetica', size='-14')
>>> l.config(font=f)
>>> print f.measure(l['text'])
11
>>> print f.measure('blahblah')
54
I hope this helps
