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;
    });
}

Documentation: http://gtk2-perl.sourceforge.net/doc/pod/Gtk2/ComboBox.html - warning: it's autogenerated and obsolete.

I suspect the python bindings have some overloading when used as an iterable.

In the perl bindings you get the treemodel object and then iterate over it using the iter_next or foreach methods.

See http://gtk2-perl.sourceforge.net/doc/pod/Gtk2/TreeModel.html#_model_foreach_func_ and http://gtk2-perl.sourceforge.net/doc/pod/Gtk2/TreeModel.html#treeiter_tree_model_4

Maybe something like this will work (untested).

my $callback = sub {
    my ($model, $path, $iter) = @_;
    my @selected = $model->get($iter);
    
    print @selected;
    # return false to ensure we keep iterating
    return;  
}

my $model = $combo->get_model;
$model->foreach ($callback);

And just for completeness, here is an example using iter_next. One could argue that the lack of callbacks make this somewhat easier to read than the foreach example.

my $iter = $model->get_iter_first();
while ($iter) {
    my @selected = $labels_model->get( $iter );
    print @selected;
    $iter = $model->iter_next( $iter );
}

my @model=$combo->get_model;
foreach(@model) {
    print $_[0];
}

Thanks for this code. (you're just missing a </code> terminating tag, but that's of little consequence in this short example).

I know almost zero about Gtk2 (and I can't find Gtk2::Combobox - do you mean Gtk2::Ex::ComboBox?) but I can say that $_[0] is likely to be undefined here. foreach just sets $_, not @_. Maybe try printing that, or using Data::Dumper or similar to dump the object, if it is one? Just a thought.

An SSCCE is always best.

I have tried it both ways with $_ and $_[0]

The docs for Gtk2::Ex::ComboBox say you want get_treeview to get the model:

my @model = $combo->get_treeview; 
print $_ for @model;
[download]

"Returns the treeview that serves as the model for the ComboBox".

Thank you Monks that is exactly what i was looking for
