I am trying to use Tk module to create a simple GUI. I would like to get the "Save and exit" button to be located at most bottom position in the GUI. When running my code below, the button is somewhere in the middle of the GUI. I have tried with -side option.


use Tk;
my $mw = MainWindow->new(-title => 'IP User config form');
my $label2 = $mw->Label(-text => 'Part 1: Mandotory fields filling');
$label2->pack();
my $f1 = $mw->Frame(-borderwidth => 2, -relief => 'groove', -width => 
+30)
->pack(-side => 'top', -fill => 'both', -expand => 1);
my $f2 = $mw->Frame(-borderwidth => 2, -relief => 'groove', -width => 
+30)
->pack(-side => 'top', -fill => 'both', -expand => 1);
$f1->Label(-text => 'Config ID')->grid($f1->Entry(-textvariable => \$d
+ss_config_id), 
$f1->Label(-text => 'Milestone ID'), 
$f1->Entry(-textvariable => \$milestone_id), -sticky => 'w', -padx => 
+2, -pady => 5); 
$f1->Label(-text => 'IPX_FQN')->grid($f1->Entry(-textvariable => \$ipx
+_fqn), 
$f1->Label(-text => 'IPX NEWLINE'), 
$f1->Entry(-textvariable => \$ipx_new_line), 
-sticky => 'w', -padx => 2, -pady => 5); 
$f1->Label(-text => 'IPX consumer groups')->grid($f1->Entry(-textvaria
+ble => \$ipx_consumer_grp), 
$f1->Label(-text => 'IPP Tag'), 
$f1->Entry(-textvariable => \$ipp_tag), 
-sticky => 'w', -padx => 2, -pady => 5); 
$f1->Label(-text => 'Process')->grid($f1->Entry(-textvariable => \$pro
+cess), 
$f1->Label(-text => 'Runset version'), 
$f1->Entry(-textvariable => \$runset_ver), 
-sticky => 'w', -padx => 2, -pady => 5);
$f1->Label(-text => 'UPF version')->grid($f1->Entry(-textvariable => \
+$upf_ver), 
$f1->Label(-text => 'Contact (username:contact_type)'), 
$f1->Entry(-textvariable => \$contact), 
-sticky => 'w', -padx => 2, -pady => 5);

#my $label3 = $mw->Label(-text => 'Release Notes Enabling', -relief=>'
+groove')->pack(-fill => 'x', -side => 'bottom');
my $label3 = $mw->Label(-text => 'Release notes');
$label3->pack();



my $values2;
my @chk_boxes2 = (
[\$values2->{notes},'Notes'],
[\$values2->{issues},'Issues'],
[\$values2->{comments},'Comments'],
[\$values2->{changes},'Changes'],
);
check_box2(\@chk_boxes2);
$f2->pack();

my $button = $mw->Button(-text => "Save and exit", -command => \&reFor
+m)->grid('-', '-', '-', -pady => 10)->pack(-side=>'bottom');

$f2->pack();
MainLoop; 
sub check_box2 {
    my $data = shift;
    my $index = 0;
    
    for my $chk_box ( @{$data} ) {
        my $column = $index % 2;
            my $row    = int($index/2);
            my $chk_x = $f2->Checkbutton(
                    -text       => $chk_box->[1],
                    -variable   => $chk_box->[0]
                    )->grid( -column => $column, -row => $row, -sticky
+ => 'w');

            #$chk_x->select if $index == 0;
            
            $index++;

    }               
my $chk_x=$f2->pack(-side=>'bottom');

}
