in reply to Is there a better way to learn Tk?

I'm not sure if this is useful, but there are two O'Reilly books for Perl/TK, the lower-level of which I found fairly useful, albeit basic.

I'm pretty sure they're called Learning Perl/TK and Mastering Perl/TK. I've found the first book in multiple libraries.
