See the Tkinter example from my threads tutorial on my website.

Short answer:
use the after method to set up a periodic scan of a queue.
In another thread, look for the new stuff, and put it on the queue when found.
there is a recipe for this sort of thing, but I keep losing links.

I'm pretty sure the book "Programmin g Python 3rd Ed." by Lutz covers
this stuff in detail. I think it mentions using threads for this sort
of thing. The wxPython wiki has a good example that I think you could
adapt for Tkinter. Just use the threading code and wrap it in your
Tkinter code and I think you'll be good to go. Here's the link: http://www.wxpython.org/maillist.php
Good luck,
Mike

There's also a good example on the wxPython wiki dealing with threads
that you should be able to adapt to Tkinter. http://wiki.wxpython.org/LongRunningTasks

Hi, now that in .NET everything is on millimeter, I was wondering how

done on pascal/delphi, but can be very easily read & converted to VB

However my question is what is the difference between "real"
millimeters and "logical" millimeters?
The source of the code is in the following thread:

Folks,
Can anyone thow some clarifying light on the following?
I have come across a column with the same name and same data contents
defined on different tables, on some the column is defined as a FLOAT
on others it is a REAL.

have absorbed all the good bits into the data warehouse). .
