Tk problem: keep sober while in callback

llancet has asked for the wisdom of the Perl Monks concerning the following question:

I have a callback that will spend a pretty long time to run, and I want to have a button, which can be pressed to stop that callback. However, while in a callback, the interface stops respond. So, how can I achieve that?

As vkon said, liberally sprinking $mw->update in your callback, will keep the gui responsive, usually. But some callbacks can take along time on a single step, so the update method won't work. You need to tell us what is in your callback.....you may need to fork it off or put it into a thread for maintaining Tk responsiveness.
