NAME

Goo::Canvas - Perl interface to the GooCanvas

SYNOPSIS

    use Goo::Canvas;
    use Gtk2 '-init';
    use Glib qw(TRUE FALSE);

    my $window = Gtk2::Window->new('toplevel');
    $window->signal_connect('delete_event' => sub { Gtk2->main_quit; });
    $window->set_default_size(640, 600);

    my $swin = Gtk2::ScrolledWindow->new;
    $swin->set_shadow_type('in');
    $window->add($swin);

    my $canvas = Goo::Canvas->new();
    $canvas->set_size_request(600, 450);
    $canvas->set_bounds(0, 0, 1000, 1000);
    $swin->add($canvas);

    my $root = $canvas->get_root_item();
    my $rect = Goo::Canvas::Rect->new(
        $root, 100, 100, 400, 400,
        'line-width' => 10,
        'radius-x' => 20,
        'radius-y' => 10,
        'stroke-color' => 'yellow',
        'fill-color' => 'red'
    );
    $rect->signal_connect('button-press-event',
                          \&on_rect_button_press);

    my $text = Goo::Canvas::Text->new(
        $root, "Hello World", 300, 300, -1, 'center',
        'font' => 'Sans 24',
    );
    $text->rotate(45, 300, 300);
    $window->show_all();
    Gtk2->main;

    sub on_rect_button_press {
        print "Rect item pressed!\n";
        return TRUE;
    }

DESCRIPTION

GTK+ does't has an buildin canvas widget. GooCanvas is wonderful. It is easy to use and has powerful and extensible way to create items in canvas. Just try it.

For more documents, please read GooCanvas Manual and the demo programs provided in the source distribution in both perl-Goo::Canvas and GooCanvas.
