    my $win = FLTK::Window->new(500, 200);
    $win->begin;
    {
        my $tabs = FLTK::TabGroup->new(10, 10, 500 - 20, 200 - 20);
        $tabs->begin;
        $tabs->callback(
            sub {
                my $self = shift;
                printf <<'END',
Tab change!
Current tab index: %d
Current tab label: %s
END
                    $self->value, # zero based index
                    $self->selected_child->label; # selected_child() is a Widget
            }
        );
        {   # Aaa tab
            my $aaa = FLTK::Group->new(10, 20, 500 - 20, 200 - 45, "Aaa");
            $aaa->begin;
            {   my $b1 = FLTK::Button->new(10, 20, 90, 25, "Button A1");
                my $b2 = FLTK::Button->new(10, 50, 90, 25, "Button A2");

            }
            $aaa->end();

            # Bbb tab
