I am converting an app from using [Gtk2::GladeXML](http://search.cpan.org/perldoc?Gtk2%3a%3aGladeXML) to [Gtk2::Builder](http://gtk2-perl.sourceforge.net/doc/pod/Gtk2/Builder.html). When getting all widgets with 

```
@widgets = $glade_object->get_widget_prefix('')

```

I could get the name (set in Glade) of a widget with 

```
$widgets[0]->get_widget_name

```

With Gtk2::Builder I fetch all widgets with

```
@widgets = $builder_object->get_objects

```

But `$widgets[0]->get_widget_name` is not known. `$widgets[0]->get_name` just gives me the widget class, e.g. GtkImage.

So my question is: How do i get the name (or id) of an widget which was created with Gtk2::Builder?

Thanks for any help.
