=head1 NAME

Gapp::Moose - Gapp widgets for your Moose classes

=head1 SYNOPSIS

  package Foo::Bar;

  use Gapp::Moose;

  widget 'label' => (

    is => 'ro',

    traits => [qw( GappLabel )],

    construct => sub {

        text => 'Hello World!'

    },

    lazy => 1,

  );

  widget 'window' => (

    is => 'ro',

    traits => [qw( GappWindow GappDefault )],

    construct => sub {

        my $self = shift;

        title => 'Gapp Application',

        content => [ $self->label ],

        signal_connect => [

            [ 'delete-event' => sub { Gtk2->main_quit } ]

        ],

    },

  );

=head1 DESCRIPTION

L<Gapp::Moose> provides sugar for adding L<Gapp> widgets to your L<Moose>
classes.

=head1 SUGAR

=head2 C<widget>

Internally, this calls C<&Moose::has> to create a new attribute with the
C<GappWidget> trait applied. 

Alternatively, you could apply the GappWidget trait yourself

 has 'widget' => (

    traits => [qw( GappWidget )],

 );

=head3 C<construct>

The C<GappWidget> trait adds the C<construct> property added to the attribute. This property
accepts a C<CodeRef> or a C<1>. The C<CodeRef> must return a list of parameters that will
be passed to the L<Gapp::Widget> during construction. C<$self> is passed in as the first
parameter to the C<CodeRef>. If C<construct> is set to one, the widget will be
constructed in its default state.
