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

Despite some of the criticisms mentioned here, and including my own frustrations, my opinion is that Perl/Tk is still worth learning. I've tinkered a bit with some others and with the possible exception of Prima it seems to be the most Perlish. Once you get the hang of it, Perl/Tk is not very difficult at all. OTOH I really want to like Wx, but trying to learn it gives me fits and leaves me cross-eyed with a headache.

The collective Perl/Tk docs actually contain sufficient information scattered about to get you going, but its a bit difficult to sort through. The following PODs should cover most of what you need to get started. Also, there should be a lot of example code somewhere under @INC at Tk/demos/.

  • Tk::UserGuide - This gives the basics and general overview. It also contains a list of standard widgets you should familiarize yourself with. Complex widgets are generally built with some combination of these.
  • Tk::option - Basic introduction to widget options database & methods
  • Tk::options - The standard widget options.
  • Tk::Widget - Generic methods for widgets.
  • Tk::pack - The most common and easiest geometry manager, its best to start with this one. There are also grid and place and form geometry managers.
  • To build complex/custom widgets or subclass existing widgets:
    • Tk::mega
    • Tk::composite
    • Tk::Derived
    • Tk::ConfigSpecs
  • Events, callbacks & binding:
    • Tk::callbacks
    • Tk::bind
    • Tk::bindtags
    • Tk::event
    • Tk::after

Update: Here's a pdf Perl Tk reference designed to be printed & folded into a booklet. Its for an older version, but may be helpful to you.
