Tk Entry not updating when textvariable changesby smithbr (Initiate) |

smithbr has asked for the wisdom of the Perl Monks concerning the following question: Hi, I am just starting with Tk and I'll admit, I don't get a chance to write a lot of Perl. But, this seems very simple to me so I can't figure out why it won't work.
I assume I must be doing something really stupid because my entry never gets updated, but $text changes from the prints. If I add $entry->configure(-textvariable=>$text) before the $mw->update() it works ok. However, all the documentation suggests if I use textvariable, changing the variable anywhere should magically update the widget text. I searched around, but the similar problems I saw were much more complicated than this so I didn't get a lot of help from them. Thanks.
