Oh great more possibly relevant code to wade through. I did google for C examples but not on Perlmonks. That's where I discovered that, in using Gtk2 in C, it seems you can just change the widget and call the the main loop again from the callback - how simple is that! - which does not work in Perl for me.
Frankly I'm tired of looking which I why I'm posting, there isn't a single clear blog or doc explaining this in Perl-gtk2. And the gtk2-perl docs are mere type and arg expanders, look auto generated, and show few or no examples whatsoever. Time to move to another toolkit?
