Multi threading could be an answer, but Tk is not thread safe.

Tk isn't "thread-safe", but it does run perfectly safely in a single thread.

That is, you can have as many background threads running as you need in your TK app, provided that none of those other threads attempt to talk directly to the GUI.

The basic method is that you start all your background threads runnung before you require Tk and build your GUI. And you then use Thread::Queue(s) to send commands from the GUI to the worker threads and another to receive back results. It is a simple, efficient mechanism that avoids all the fuss and bother of buffered pipes or sockets and select loops.

With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.

The start of some sanity?
