Danny, I got it:


from Tkinter import *
from time import *

def my_update():
   for i in range(3):
     tv.set("Now it's %d"%i)
     root.update()
     sleep(1)

root=Tk()
tv=StringVar()
Entry(textvariable=tv).pack()
tv.set("Initial Value of StringVar")
Button(text="Update", command=my_update).pack()
root.mainloop()



Trick is call to update() - which I found by looking at a few pages before the one your URL pointed me to, so THANKS!!! again.
