I'm not sure exactly what you want, but it sounds like you are looking for a Tk::Adjuster. See Tk::Adjuster, how to keep proportions for maintaining ratios. Here is a simple example with no ratio. 
#!/usr/bin/perl
use warnings;
use strict;
use Tk;
use Tk::Pane;

my $mw = MainWindow->new();

my $pane = $mw->Scrolled('Pane',
 -sticky => 'nsew',
 -scrollbars => 'osoe',
)->pack(-fill => 'both',-expand => 1);

my $i;
for ($i = 0; $i <= 5; $i++){

my $frame = $pane->Frame(
   -relief => 'ridge',
   -bd     => 1,)
     ->pack(-side => 'top',-fill => 'both',-expand => 1);

my $adjust = $pane->Adjuster();
$adjust->packAfter($frame, -side => 'top',-fill=>'both',-expand=>1);

my $label = $frame->Label(-width => 30,
    -text  => "Frame ". $i,)->pack();
}

my $frame = $pane->Frame(
   -relief => 'ridge',
   -bd     => 1,)
     ->pack(-side => 'top',-fill => 'both',-expand => 1);

my $label = $frame->Label(-width => 30,
    -text  => "Frame 6 ")->pack();

MainLoop;
