Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

Hello, i am hoping you can help me. I am using the Win32::GUI module and i have a listview added. I am trying to catch a button-click on a column name so i can sort on that column. I am looking through the documentation but i can't find anything. Here is what i have so far: 

use strict;
use warnings;
use Win32::GUI();
use DBI;
my $mw = Win32::GUI::Window->new(
-text => "View",
-size => [ 550, 500 ],
-pos => [ 200, 200 ],
);

sub mw_Terminate { return -1 }

my $lv = $mw->AddListView(
-pos => [ 20, 20 ],
-size => [ 400, 400 ],
-gridlines => 1
);

$lv->InsertColumn( -item => 0, -text => "PID", -width => 50);
$lv->InsertColumn( -item => 1, -text => "Name", -width => 100);
$lv->InsertColumn( -item => 2, -text => "Address", -width => 100);
$lv->InsertColumn( -item => 3, -text => "Salary", -width => 100);

my $dbfile = 'C:/code/lqs.db';
my $dbh = DBI->connect("dbi:SQLite:dbname=$dbfile","","");
my $stmt = qq(select id,name,address,salary from deliver order by sala
+ry desc);
my $sth = $dbh->prepare($stmt);
$sth->execute;
while(my @row = $sth->fetchrow_array()){
    $lv->InsertItem(-text => [$row[0],$row[1],$row[2],$row[3]]);
}

$mw->Show;
Win32::GUI::Dialog();

    Sure: 

    use strict;
use warnings;
use Win32::GUI();
use DBI;
my $mw = Win32::GUI::Window->new(
-text => "ListView",
-size => [ 500, 500 ],
-pos => [ 200, 200 ],
);

sub mw_Terminate { return -1 }

my $lv = $mw->AddListView(
-name => "view",
-pos => [ 20, 20 ],
-size => [ 400, 400 ],
-gridlines => 1
);

$lv->InsertColumn( -item => 0, -text => "PID", -width => 50);
$lv->InsertColumn( -item => 1, -text => "Name", -width => 100);
$lv->InsertColumn( -item => 2, -text => "Address", -width => 100);
$lv->InsertColumn( -item => 3, -text => "Salary", -width => 100);

my $dbfile = 'C:/code/lqs.db';
my $dbh = DBI->connect("dbi:SQLite:dbname=$dbfile","","");
my $stmt = qq(select id,name,address,salary from deliver order by sala
+ry desc);
my $sth = $dbh->prepare($stmt);
$sth->execute;
while(my @row = $sth->fetchrow_array()){
    $lv->InsertItem(-text => [$row[0],$row[1],$row[2],$row[3]]);
}

$mw->Show;
Win32::GUI::Dialog();

sub view_ColumnClick{
    my $var = shift;
    $lv->DeleteAllItems;
    if($var == 0){
        $stmt = qq(select id,name,address,salary from deliver order by
+ id asc);
        $sth = $dbh->prepare($stmt);
        $sth->execute;
        while(my @row = $sth->fetchrow_array()){
            $lv->InsertItem(-text => [$row[0],$row[1],$row[2],$row[3]]
+);
        }    
    }
    elsif($var==1){
        $stmt = qq(select id,name,address,salary from deliver order by
+ name asc);
        $sth = $dbh->prepare($stmt);
        $sth->execute;
        while(my @row = $sth->fetchrow_array()){
            $lv->InsertItem(-text => [$row[0],$row[1],$row[2],$row[3]]

        while(my @row = $sth->fetchrow_array()){
            $lv->InsertItem(-text => [$row[0],$row[1],$row[2],$row[3]]
+);    
        }
    }
    elsif($var==3){
        $stmt = qq(select id,name,address,salary from deliver order by
