Perl Tk Scrolled widget callbacks

[ghosh123]

Hi
I have a scrolled widget in my Perl Tk code. How can I introduce a callback just to check the -wrap value of it and take some action accordingly.

Following is just a snippet of my code :

use warnings;
use strict;
use Tk;

my $mw = new MainWindow;
$mw->geometry("200x200");
my $frame = $mw->Frame()->pack;

my $textbox = $frame->Scrolled('Text',
                                -scrollbars => 'soe',
                                -foreground => 'blue',
                                -background => 'white',
                                -wrap => 'none',
                                 )->pack;
$textbox->insert('end', "This is scrolled widget.\nThis is scrolled wi
+dget.This is scrolled widget"); 

MainLoop;

I want the callback to be called when I click RightMouseButton > View > Wrap on the scrolled frame and change the Wrap to something.
Please help. Thanks.
My callback should be like below

sub func
{
my $wr = $textbox->Subwidget('scrolled')->cget(-wrap);

if ($wr =~ /\bnone\b/)
{
    # do something
}
else
{
        # do something else
}
