Trying to debug my script, I broke it down to bare minimum: 
#!/usr/bin/perl
use strict;
use warnings;
use Tk;
use Tk::Pane;

my $mw = MainWindow->new( );
$mw->minsize(200,300);

my $pane = $mw->Scrolled( 'Pane',
    -scrollbars => 'e',
    -border => 2,
    )->pack(-fill=>'both', -expand=>1);

foreach my $x (1..100) {
    my $label = $pane->Label(
        -text    => $x,
    )->pack(-side=>'top', -fill=>'x', -expand=>0);
#    $pane->yview(moveto => 1);
}
MainLoop;

Above script suppose to create a Pane, then populate it with 100 labels.
So far so good.


Uncommenting the line $pane->yview($label);, it is suppose to scroll to the bottom.
But I get this error:

Can't call method "Call" on an undefined value at C:/Perl/site/lib/Tk/Pane.pm line 346.

What is wrong?

According to documents (http://search.cpan.org/~srezic/Tk/Tk/Pane.pm):
$pane->yview(moveto => 1) Is how to scroll to the very bottom but it is not doing so. Why?
