The Gtk2-Perl FAQ has a question along these lines [1].

You use the add_watch method to watch a filehandle for changes, then
your anonymous subroutine gets called whenever some data appears on
that filehandle.  It would be up to you to have that anonymous
subroutine parse the data and make any changes to controls on your
form.

I would start with the example listed in the FAQ, and search for
"Gtk2::Helper" or the actual class Gtk2::Helper calls, "Glib::IO",  in
the mailing list archives to find more examples of similar problems.

Thanks,

Brian
