Apparently, we never added an overload for it to make it behave like in
Gtk2, so you can ask perli11ndoc how to use it:

---
# perli11ndoc Gtk3::ComboBox::get_active_iter
METHOD

  Gtk3::ComboBox::get_active_iter [available since 2.4]

SYNOPSIS

  ($retval, $iter) = $object->get_active_iter ()

DESCRIPTION

  ...

RETURN VALUES

  • gboolean
    %TRUE if @iter was set, %FALSE otherwise

  • iter: Gtk3::TreeIter
    A #GtkTreeIter
---

Use the bool $retval to know whether $iter is valid.
