NAME

Acme::Gtk2::Ex::Builder - Funny Gtk2 Interface Design Module

VERSION

version 0.006

SYNOPSIS

use strict;
use warnings;
use Gtk2 -init;
use Acme::Gtk2::Ex::Builder;

my $app = build {
    widget Window => contain {
        info id           => 'window';
        set  title        => 'Awesome App';
        set  default_size => 200, 100;
        set  position     => 'center';
        on   delete_event => sub { Gtk2->main_quit; };

        widget Button => contain {
            set label  => 'Action';
            on clicked => sub { say 'Seoul Perl Mongers!' };
        };
    };
};

$app->find('window')->show_all;
Gtk2->main;

METHODS

find

Find and get widget by ID. You can find widget only you set id with info function.

my $app = build {
    widget Window => contain {
        info id => 'my-window';
    };
};

my $window = $app->find('my-window');

FUNCTIONS

build

This function acts like ordinary "new" method. It is exported by default and returns Acme::Gtk2::Ex::Builder object. It can contains several widget functions.

my $app = build {
    widget Window;
    widget Dialog;
    widget FileChooser;
    widget VBox;
};

widget

This function creates the Gtk2 widget. In fact when you use this, Gtk2::XXX->new will be called. See Gtk2 and Gtk2 API reference.

Following code will call Gtk2::Window->new.

my $app = build {
    widget Window;
};

If you need more children widgets, use contain, then call widget again and again.

my $app = build {
    widget Window contain => {
        widget HBox => contain {
            widget Button;
            widget Button;
            widget Button;
        };
    };
};

If you have to use more parameters for constructor, then specify additional parameters after the widget block. Following code create Gtk2::SimpleList with additional timestamp, nick and message parameter. See Gtk2 and Gtk2 API reference.

my $app = build {
    widget SimpleList => contain {
        info id              => 'logviewer';
        set  headers_visible => FALSE;
        set  rules_hint      => TRUE;
    }, (
        timestamp => 'markup',
        nick      => 'markup',
        message   => 'markup',
    );
};

info

This function sets additional information. Since it is not realted to Gtk2 functions, attributes, signal and properties, so save anything what you want or need.

Currently id and packing have some special meanings. id is used for widget method to find widget. packing is used for Gtk2::VBox and Gtk2::HBox.

my $app = build {
    widget Window => contain {
        info id             => 'window';
        set  title          => 'Seoul.pm irc log viewer';
    };

    widget HBox => contain {
        info id      => 'hbox';
        info packing => TRUE, TRUE, 1, 'start';

        widget ScrolledWindow => contain {
            set policy => 'never', 'automatic';
        };
    };
};

on

This function connects signals for specified widget. Actually it is same as $widget->signal_connect. See Gtk2 and Gtk2 API reference.

my $app = build {
    widget Window => contain {
        on   delete_event => sub { Gtk2->main_quit };
        widget VBox => contain {
            widget ToggleButton => contain {
                set  label   => "show/hide";
                on   toggled => \&toggled;
            };
            widget Button => contain {
                set  label   => 'Quit';
                on   clicked => sub { Gtk2->main_quit };
            };
        };
    };
};

set

This function sets properties for specified widget. Actually it is same as $widget->set_xxx. See Gtk2 and Gtk2 API reference.

my $app = build {
    widget Window => contain {
        set  title        => 'Awesome App';
        set  default_size => 200, 100;
        set  position     => 'center';
    };
};

contain

This function is used to set attributes, connect signal, add additional information or contain children widgets.

my $app = build {
    widget Window => contain {
        info   ...
        set    ...
        on     ...
        widget ...
    };
};

SEE ALSO

The idea of this module is stealed from Seoul.pm Perl Advent Calendar, 2010-12-24. I think Gtk2::Ex::Builder will be released someday by the article's author. But before the release, this module colud be helpful for you who likes Gtk2 but too lazy to type all code by his/her own hands.
