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 {

                                                            # see client_start below
                                                    },
                                            },
                                    });
                            },

                                                            Select => $session->callback('listbox_select')
                                                    ),

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.
