note Marshall <i>The CPAN documentation seems plentiful but incomplete. For example, if there are parameters for Tk::MainLoop or any special methods for Tk::MainWindow it can't be discerned from the documentation.</i><p> I have the Perl/Tk Pocket Reference by Stephan Lidie. I counted 27 methods that can be called on a mainwindow in that chapter. Appendix A of Learning Perl/Tk has a table of common widget methods. But that book is out of print. I don't know about the Pocket Reference. But is very handy and has a lot more than the Appendix A table. This isn't a tutorial, it is a "cut to the chase", here is a widget and here are the methods. There aren't any examples. <p> Update: http://www.amazon.com/Perl-Pocket-Reference-Stephen-Lidie/dp/1565925173/ref=sr_1_3?ie=UTF8&s=books&qid=1241797000&sr=1-3<br> $10 on Amazon. I recommend this. 762748 762748
