Here is a pager method I'm using in Tk. Basically you put all the keys to be displayed into an @list, then you parse through @list pushing them into @{pager{$count}}, and incrementing $count when scalar @{pager{$count}} exceeds the desired pagesize. 
######################################################################
+######## 
my $pagesize = 10; #elements per page

sub setup_pager{

my $arrayref = $_[0];  #pass in @list
my $new = $_[1];       #conditional for new

%pager=(); #empty pager 
my $keytot = scalar @{$arrayref};
#print "$keytot\n"; 

my $key;
#setup pages####################### 
my $count = 1;
foreach $key (@{$arrayref}){
      push @{$pager{$count}},$key;
         if(scalar @{$pager{$count}} > ($pagesize - 1) ){$count++}
   }
################################## 

if($new){&display_page($count)}
   else{ &display_page(1) };
 
}
######################################################################
+########## 
sub display_page{
$page = shift;
my $e = shift || 1; #which entry to display, defaults to 1 
                    #top is admin at 0 

$pagetot = scalar(keys %pager);
$pagerlab->configure(-text => "Page $page of $pagetot");

#blank previous thumbnail entries 
foreach(1..$pagesize){$h->hide('entry',$_)}

#load  page  
foreach my $key (@{$pager{$page}} ){
        $ethumbs{$e}->blank;
        $ethumbs{$e}->read($info{$key}{'thumbnail'});

        $h->itemConfigure ($e, 0,
           #image is read directly in Photo object above 
           -text => $info{$key}{'comment'},
           );

         $h->itemConfigure($e, 1,
           -text => "$info{$key}{'name'}\n$info{$key}{'key'}",
           );

      $h->show('entry',$e);
      $e++;
    }

}
