. No idea what that may do.
I see your code uses Tcl::Tk, which I've never looked into. I've been playing around with Perl/Tk and implemented some very simple Tk code in the latest release of my script. I'm not sure I want to switch over to Tcl::Tk, but I can't see any mention of the tablelist widget in any Perl/Tk documentation. Tcl::Tk is supposed to be simply be another way to acces the same Tk stuff that one can use with the Tk module, so one would expect the same widgets to be available... I'm getting confused here. Well, who would be better able to clear this up than the Tcl::Tk developer, right?
