The fact that he doesn't mention Perl at all is a bit of a clue in. Tk is an extension to Tcl, not Perl. Yes, there is a Perl interface for it, but his question is a generalised one regarding the configuration of Tk, not something specific to the Tk Perl module.

If it can be achieved with Tk::options, by all means enlighten us. It will be a useful contribution if he is indeed using the perl Tk module.
