Dear Monks

I am trying to set up an action using radio buttons that when it is selected it changes the readonly state of the text field (see below code). This code runs but the subroutine does not work when the radio button is selected. I expect that the –click option is not doing what I want it to do, and my googling for solutions technique is not yielding any suggestions. Does anyone have any suggestions on how to get the functionality that I am looking for?

#!perl -w
use strict;
#use warnings;
use Win32::GUI();

my $w = 250;
my $h = 100;
my $main = Win32::GUI::Window->new(
    -name => 'Main',
    -text => 'Example Window',
    -width => $w,
    -height => $h,
    -resizable => 0
);

$main->AddRadioButton (
        -name    => 'radio_1',
        -pos     => [10, 10],
        -size    => [12,12],
        -checked => '1',
        -click => sub{$main->user_text->Change(-readonly => 1);},
);

$main->AddLabel(
    -text => "Disable Textfield",
    -pos => [25,10],
);

$main->AddRadioButton (
        -name    => 'radio_2',
        -pos     => [10, 30],
        -size    => [12,12],
        -click => sub{$main->user_text->Change(-readonly => 0);},
);

$main->AddLabel(
    -text => "Enable Textfield",
    -pos => [25,30],
);

$main->AddTextfield(
    -name => 'user_text',
    -pos => [110,28],
    -size => [60,20],
    -align => 'left',
    -readonly => 1,
);

$main->Show();
Win32::GUI::Dialog();
