Currently I have been trying to build a chat client using the Perl Object Environment and Gtk2. I have been talking on the POE mailing list and have made progress but currently have ran into a few snags lately. One problem that I have encountered is that when you close the client, the GUI closes but the program is still running. I suspect that the Component::Client session is still running. Another problem is that when the client connects to the server, nothing is displayed in the textview but when it encounters the client error event, it is displayed in the text box. I would appreciate any help.

use warnings;
use strict;

use Gtk2 -init;
use Glib qw/TRUE FALSE/;
use POE::Kernel { loop => "Glib" };
use POE::Session;
use POE::Component::Client::TCP;

my $buffer = Gtk2::TextBuffer->new;

sub ui_start {
    my ( $kernel, $session, $heap ) = @_[ KERNEL, SESSION, HEAP ];
    
    $heap->{main_window} = Gtk2::Window->new("toplevel");
    $kernel->signal_ui_destroy( $heap->{main_window} );

    my $table = Gtk2::Table->new(3, 2, FALSE);
    
    my $label = Gtk2::Label->new("Chat Client Test");
    
    my $button = Gtk2::Button->new("Send");
    
    my $textview = Gtk2::TextView->new_with_buffer($buffer);
    $textview->set_cursor_visible (FALSE);
    my $swindow = Gtk2::ScrolledWindow->new( undef, undef);
    $swindow->set_policy( 'automatic', 'automatic');
    $swindow->set_shadow_type( 'etched-out');
    
    $swindow->add( $textview);
    
    my $entry = Gtk2::Entry->new();
   
    $table->attach_defaults($label, 0, 1, 0, 1);
    $table->attach_defaults($swindow, 0, 2, 1, 2);
    $table->attach_defaults($entry, 0, 1, 2, 3);
    $table->attach_defaults($button, 1, 2, 2, 3);
    $heap->{main_window}->add($table);

    $heap->{main_window}->show_all();
