Hello. I need an example, how create virtual listview with Win32::GUI. I want to know, how to use LVM_SETITEMCOUNT hook and where in code I need to add items in ListView?

use warnings;
use strict;
no strict 'subs';


my @list_items;

use constant LVM_SETITEMCOUNT => 4143;

use Win32::GUI::Constants qw(/^(MB_|ILC_|IDYES|SB_|DT_|WS_|LVS_)/);
use Win32::GUI();


my $wnd = Win32::GUI::Window->new(
    -size => [500, 500]
);

my $lines = $wnd->AddTextfield(
    -prompt => ['Lines:', 80],
    -pos => [160, $wnd->ScaleHeight - 30],
    -height => 24,
    -width => 100,
    -popstyle => WS_BORDER,
    -tabstop => 1,
    -text => 5000
);


my $refresh_btn = $wnd->AddButton(
    -pos => [10, $wnd->ScaleHeight - 30],
    -size => [100, 24],
    -text => 'Refresh',
    -onClick => \&update_list
);

my $list = $wnd->AddListView(
    -name => 'list',
    -pos => [10, 10],
    -size => [$wnd->ScaleWidth - 20, $wnd->ScaleHeight - 50],
    -gridlines => 1,
    -popstyle => WS_BORDER,
    -pushstyle => LVS_OWNERDATA 
);
$list->Hook(LVM_SETITEMCOUNT, sub {
    ################
    # What I need to write there?
    ################
});

$list->InsertColumn(
    -width => 24
);

$list->InsertColumn(
    -width => 200
);



$wnd->Center();
$wnd->Show();
Win32::GUI::Dialog;



sub update_list() {
    my $line = 0;
    my $max_lines = $lines->Text();
    
    $list->Clear();
    
    @list_items = ();
    for (1 .. $max_lines) {
        push(@list_items, {-text => [$_, rand(9999999)]});
    }
    
    $list->SetItemCountEx(scalar @list_items, 0);
}
