Using the PerlMonks Chatter Box GUI Client as an example, we'll see how to integrate Tk safely into a threaded program via Thread::Queue, or via MCE to avoid threads

PM::CB::G or Perl Monks Chatter Box GUI Client is a Tk program that uses threads to keep the GUI responsive even when communicating over the net. Threads are, by the official documentation, discouraged - but if one knows how to use them safely, they can help you. MCE::Shared has the API very similar to Thread::Queue so you can easily switch between the two.
