Hi, here is a little example which should show you the ropes on handling the scrollbar options. It is slightly exaggerated for demo purposes. :-)

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

my %frames;  
my %subframes;
my %labels;
my %buttons;
my $mw = MainWindow->new;

my $pane = $mw->Scrolled("Pane",
   -scrollbars => 'se',
   -sticky => 'nsew',
   -bg => 'black',
   -width => 300,
   -height => 300
)->pack(-expand => 1, -fill => 'both');
my $realpane = $pane->Subwidget('scrolled');

my $xbar = $pane->Subwidget('xscrollbar');
my $ybar = $pane->Subwidget('yscrollbar');

$ybar->configure(-background=>'blue', -activebackground=>'blue', 
                  -troughcolor => 'black', -width=> 50);
$xbar->configure(-background=>'green', -activebackground=>'green',
                 -troughcolor => 'black', -width=> 50);


foreach my $row (0 .. 3) {
    $frames{$row} = $pane->Frame(-bg => 'black')->pack(
     -padx => 5,
     -pady => 5,
     -expand => 1,
     -fill => 'both', 
     -anchor => 'nw',
   );
  
   foreach my $col (0 .. 3) {
      createTile($row, $col);
   }
}

MainLoop;

sub createTile
{
   my ($row, $col) = @_;

   $subframes{$row}{$col}{'mainframe'} = $frames{$row}->Frame(
        -bg => 'black')->pack(
                           -side => 'left',
                       -padx => 5,
                           -pady => 5,
                           -expand => 1,
                           -fill => 'both', 
                           -anchor => 'nw',
        );

   my $frame = $subframes{$row}{$col}{'mainframe'};

   my $sc = $frame->Scrolled('Canvas',
      -scrollbars => 'osoe',
      -scrollregion => [0, 0, 1200, 1200],
      -width => 125,
      -height => 125,
      -background => randColor()
   )->pack(-fill=>'both',-expand => 1, -side =>'top');

   my $count = int(rand(6)) + 2;
   foreach my $i (1 .. $count) {
      my ($x, $y) = (randNumber(), randNumber());
      my $size = randNumber();
      $sc->createRectangle($x, $y, $x+$size, $y+$size,
         -fill => randColor(),
         -outline => 'black',
         -width => 2
      );
   }

   #miniframe for labels

   #labels
   $labels{$row}{$col}{1} = $subframes{$row}{$col}{'subframe_a'}->Labe
+l(

        -bg => 'black',
        -fg => 'green',
     )->pack(-side => 'left', -padx => 5);

  $labels{$row}{$col}{2} = $subframes{$row}{$col}{'subframe_a'}->Label
+(

        -bg => 'black',
    -fg => 'hotpink',
     )->pack(-side => 'right', -padx => 5);
