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.
