Re: Need a callback for Tk radio button deselect

Does this give you ideas?

#!/usr/bin/perl
use Tk;
use strict;

my $val;

my $mw = new MainWindow;
$mw->Checkbutton(onvalue => "I am selected",
                offvalue => "I am deselected",
                variable => \$val)
  ->pack;
$mw->Entry(textvariable => \$val)->pack;

MainLoop;

zentara, I'm not sure your example helps. What I am after is a callback for a radiobutton. My radiobutton widget is detecting changes of value of the common -variable, and visibly changes its appearance. It looks like you are doing something equivalent by typing into the entry box. However, no callback results; this is what I am really after, in order to do some processing when the widget is deselected. -- I'm Not Just Another Perl Hacker	[reply]
