It's slightly more complicated: you have to use the foreach method of the model to iterate on its rows, supply a callback to it, in which you use the Gtk2::TreeIter to get the value out of each row.
Working example:
#! /usr/bin/perl
use strict;
use warnings;
use feature qw/say/;
use Gtk2 -init;
my $window = Gtk2::Window->new ('toplevel');
$window->signal_connect (delete_event => sub { Gtk2->main_quit });
my $vbox = Gtk2::VBox->new();
$window->set_size_request (130, 100);
$window->add($vbox);
my $combo = Gtk2::ComboBox->new_text();
foreach (qw/foo bar baz/) {
$combo->append_text ($_);
}
$vbox->pack_start($combo, 0, 0, 5); # expand?, fill?, padding
my $button = Gtk2::Button->new ('extract');
$button->signal_connect (clicked => \&extract);
$vbox->pack_start($button, 1,1,5);
$window->show_all;
Gtk2->main;
sub extract {
my $active_text = $combo->get_active_text();
print "active text: $active_text\n";
print "all rows:\n";
my $model = $combo->get_model();
$model->foreach(sub {
my ($store, $path, $iter) = @_;
my $value = $model->get_value($iter, 0); # assuming there is o
+ne column only in the model
print $value."\n";
return 0;
});
}

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>

-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
