NAME

POE::Component::XUL - Easier use of XUL::Node when using POE

DESCRIPTION

POE::Component::XUL uses POE::XUL::SessionManager and POE::XUL::Session in a slightly different way to allow poe callbacks to your session for XUL application calls.

SYNOPSIS

            

              
              
use POE qw( Component::XUL );
use XUL::Node;
use XUL::Node::Application;
use base 'XUL::Node::Application';
POE::Session->create(
        inline_states => {
                _start => sub {
                        my ($kernel, $heap, $session) = @_[KERNEL, HEAP, SESSION];
                        POE::Component::XUL->spawn({
                                port => 8001,
                                root => '/usr/local/xul-node',
                                apps => {
                                        # a callback
                                        Test => $session->callback("client_start"),
                                        # or a sub
                                        Test2 => sub {
                                                # code for app Test2 here
                                                # see client_start below
                                        },
                                },
                        });
                },
                client_start => sub {
                        my ($kernel, $heap, $session) = @_[KERNEL, HEAP, SESSION];
                        # the label object is kept in the heap to use it on callbacks
                        return Window(
                                VBox(FILL, $heap->{label} = Label(value => 'select item from list'),
                                        ListBox(FILL,
                                                (map { ListItem(label => "item #$_") } 1..10),
                                                Select => $session->callback('listbox_select')
                                        ),
                                ),
                        );
                },
                listbox_select => sub {
                        my ($kernel, $heap, $session, $event) = (@_[KERNEL, HEAP, SESSION], $_[ARG1]->[0]);
                        print "[".$event->{session}."] picked #".($event->{selectedIndex}+1)."\n";
                        # example of doing 2 or more things in request
                        # set the label text and make it change colors
                        my @colors = ('red','blue','green','yellow','white','black');
                        return $heap->{label}->value("you selected #".($event->{selectedIndex}+1)).
                                $heap->{label}->style('color:'.$colors[(int(rand($#colors)))]);           
                },
        },
);
$poe_kernel->run();
            
          

DESCRIPTION

POE::Component::XUL allows you to use poe callbacks in your XUL::Node apps. In its current state, XUL::Node doesn't give you a way to use POE easily in your apps, but with this component you will have the control you need.
