Re: How to run 2 buttons in parallel in Perl/Tk

[zentara]

You are creating threads after you invoked some Tk gui code. Tk is not threadsafe, and you cannot make threads that way. See Re: Perl Tk and Threads or you can switch to Gtk2 which allows your type of code, with some restrictions.

Hi Zentara, thanks for your answer, again. May I know how do people usually do if they want to kick run numerous job together? Seems that the treads method not suitable here, and I doubt to switch to Gtk2 now since my code now is pretty done except for this "RunAll" button :(

You can use threads made before any gui code is called, and send commands to be eval'd by them thru threads:shared variables. See Tk-with-worker-threads

The alternative, is to fork off your parallel processes, and that is the way it was originally done before the coming of perl threads.
