( #3333=superdoc: print w/replies, xml ) Need Help??

Thanks a lot Ken .
Well to give you some hint of how I want the gui to be :

1. There will be a 'load' button on it which will load for example two jobs. Job1 and Job2 under columns Jobname and Status.
2. Primarily those job1 and job2 status should be Stopped.
3. There will be one more button Start, clicking start button those two jobs should start running in the background.
4. Those jobs will be simple perl file with just a sleep statement for 20s and 10s respectively.
5. As long as those jobs will be running , the job status under status column should change to 'Running' from 'Stopped'. And as the jobs finished their status will be changed to 'Finished'.
6. The gui should not know anything about what job is running, but through socket it should get the information and display its status accordingly.
7. After clicking 'start' button, the text on it should change to 'stop'. And then pressing 'stop' it should toggle back to 'start' and accordingly the job status should also change to 'Stopped' from 'Running'.

I have little modified your code to explain my wish. I have implemented #1 and #2 mentioned above. But need help on #3 to #7.

#!/usr/bin/perl use strict; use warnings; use Tk; use IO::Socket; use Tk::HList; my $status = ''; my $mw = MainWindow->new; $mw->geometry("200x100"); my $control_F = $mw->Frame()->pack(-side => 'bottom'); $control_F->Button(-text => 'Listen', -command => sub { start_server(\$mw, \$status) } )->pack(-side => 'left'); $control_F->Button(-text => 'Load', -command => sub { load_job() } )->pack(-side => 'left'); $control_F->Button(-text => 'start', -command => sub { } )->pack(-side => 'left'); $control_F->Button(-text => 'Quit', -command => sub { exit } )->pack(-side => 'left'); my $status_F = $mw->Frame()->pack(-side => 'top'); #$status_F->Label(-text => 'Status:')->pack(-side => 'left'); #$status_F->Label(-textvariable => \$status)->pack(-side => 'left'); my $hlist = $status_F->Scrolled( 'HList', -scrollbars => 'ose', -columns => 2, -header => 1, -height => 5, )->pack( -fill => 'both', -expand => 1 ); my $label1 = $hlist->Label( -text => "Jobname", -anchor => 'w' ); $hlist->headerCreate( 0, -itemtype => 'window', -widget => $label1 ); my $label2 = $hlist->Label( -text => "Result", -anchor => 'w' ); $hlist->headerCreate( 1, -itemtype => 'window', -widget => $label2 ); sub load_job { $hlist->add(0); $hlist->itemCreate(0,0,-text=> "job1"); $hlist->itemCreate(0,1,-text=> "stopped"); $hlist->add(1); $hlist->itemCreate(1,0,-text=> "job2"); $hlist->itemCreate(1,1,-text=> "stopped"); } MainLoop; sub start_server { my ($mw_ref, $status_ref) = @_; my $server = IO::Socket::INET::->new( Proto => 'tcp', LocalPort => 55555, Listen => SOMAXCONN, Reuse => 1 ) or die "Server can't start: $!"; my $client = $server->accept(); $client->autoflush; $$mw_ref->fileevent($client, 'readable', sub { if (defined(my $read = <$client>)) { chomp $read; $$status_ref = $read; } }); }
