returning values from Perl-Tk eventsby thunders (Priest) |

thunders has asked for the wisdom of the Perl Monks concerning the following question:
Hello fellow Monks, I've been working with Tk for a few days now and I've run into something I can't get my brain around. How can I return or pass a value from a button event? I'm writing an application that will let me compare photographs from a directory two at a time until I've decided on a favorite. The problem comes with trying to achieve this using Tk Buttons. I've tried several different methods, but I still cant figure how to pass an array or return it through a button event subroutine, so that my array will eventually shrink as I make choices. Any suggestions?
