Setting an iter from an ID value

[Daniel Kasak <dkasak nusconsulting com au>]

Hi all.

I have some code which I'm not completely happy with.
I have a combo box with a Gtk2::ListStore model, which contains 2 
fields: an ID field and a string field.
Here's how I'm currently selecting the iter:

> my $iter = $widget->get_model->get_iter_first;
>
> $widget->get_child->set_text(""); # In case no match is found for some 
> reason
>
> while ($iter) {
>     
>     if ($id_from_database eq $widget->get_model->get($iter, 0)) {
>         $widget->set_active_iter($iter);
>         last;
>     }
>     
>     $iter = $widget->get_model->iter_next($iter);
>     
> }


This works, but doesn't seem like a very economical way of doing things.
I've thought about getting the string field from the database and using 
$widget->get_child->set_text($string) but that also seems kinda dodgy, 
and won't work if there are duplicate strings ( not that there should 
be, but anyway ... )

Is there a better way of doing this?
