I'd like to know how to test the result of get_active_iter() when no
element is active.In Gtk2 it returns undef but in Gtk3 it returns a
Gtk3::TreeIter object that isn't usable.
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.
