> I have a Tk GUI app. There are "Start" and "Stop" buttons on my GUI. After pressing "Start" button, my app will execute a command in a thread, maybe copy a large file. It will take a long time. At the moment, I want to press "Stop" button to stop this action immidiately. And then, I can press "Start" button to copy that file again. This is what I want. Do you have any idea? Or is there another way to achieve this?

First off, no need to use threads here at all.

Tcl/Tk event driven model will handle it.  Take a look at the help/man pages 
for the fcopy command.  To stop the transfer, just close both files in the 
procedure invoked by the "Stop" button.
