Just to give you a little more help with the scrollbar, here is a little example to show what happens when you override the scrollbar callback. Notice in this example, if I override the scrollbar's internal callback, it will stop working unless you manually do it.
#!/usr/bin/perl
use warnings;
use strict;
use Tk;
my $mw = MainWindow->new();
my $text_box = $mw->Scrolled("Text",
-scrollbars => 'e',
-relief => 'sunken',
-takefocus => 1)
->pack(-expand => 1, -fill => 'both');
for(1..1000){
$text_box->insert('end', "$_ test\n");
$text_box->see('end');
}
$text_box -> Subwidget("yscrollbar")->configure(
-background => "lightgreen",
-troughcolor => "black",
#comment out the following line to restore normal
#scroll function
-command => \&scrollcallback,
);
MainLoop;
#if you specify a scrollcallback, you will override the
#normal scroll behavior.
sub scrollcallback{
#uncomment the following line to restore the normal function
# $text_box->yview(@_);
#do your additional stuff here
print "1\n";
}
I'm not really a human, but I play one on earth.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
are good places to start.
