The code is as follows. I have edited a few lines. 
my $fright = $mw->Frame(-borderwidth=>3)->pack(-expand=>1, -side=>'lef
+t', -fill=>'both');
my $fedit = $fright->Frame(-relief=>'sunken',
    -borderwidth=>5)->pack(-expand=>1, -side=>'top', -fill=>'both');
my $noteb = $fedit->NoteBook(-relief=>'raised', -background=>'skyblue'
+)->pack(-expand=>1, -side=>'top', -fill=>'both');
my $nb1 = $noteb->add(1,-label=>"Stdout");
my $nb2 = $noteb->add(2,-label=>"View");
my $tedit = $nb1->Scrolled('Text', -scrollbars=>'oe')->pack(-expand=>1
+, -side=>'top', -fill=>'both');
    $tedit->configure(-background=>'AliceBlue');
my $fileview = $nb2->Scrolled('ROText', -scrollbars=>'oe')->pack(-expa
+nd=>1, -side=>'top', -fill=>'both');
    $fileview->configure(-background=>'AliceBlue');
# Tie STDOUT to Text widget
tie *STDOUT, 'Tk::Text', $tedit;
