My apologizes, WxPerl IS in fact documented, but most of the documentation is introduction material and perl object model oddities. Samples are merely "hello world", and more elaborated samples are only available in C++. I know how it can be difficult and time consuming writing such documentation. Now most of the time is still dedicated to make it work.
IMHO, WxPerl despite its real power, is still lacking of an accompagning book (there's here matter for a Chapter XI of the Perl In A Nutshell, even perhaps for a dedicated tome [which animal? *g*]). But don't be mistaken about my remarks, I DO prefer from far using WxPerl than Tk...
