bug

Hello

When creating a combobox using a GtkListStore, PHP-GTK gives me this
error:

(combobox_model.php:7672): GLib-GObject-WARNING **:
IA__g_object_new_valist: object class `GtkComboBox' has no property
named `text-column'

Does anyone knows what it can be ? The code is below:

<?php
$window = new GtkWindow;
$window->set_default_size(200,100);
$window->set_border_width(20);
$window->set_position(GTK::WIN_POS_CENTER);

$model = new GtkListStore(GObject::TYPE_OBJECT, GObject::TYPE_STRING);

$comboBox = new GtkComboBox($model); // => the error is here

$cell_renderer1 = new GtkCellRendererPixbuf();
$cell_renderer2 = new GtkCellRendererText();

$comboBox->pack_start($cell_renderer1, false);
$comboBox->pack_start($cell_renderer2, true);

$comboBox->set_attributes($cell_renderer1, 'pixbuf', 0);
$comboBox->set_attributes($cell_renderer2, 'text', 1);

$items   = array();

$items[] = array('ico_pdf.png', 'Arquivo PDF');
$items[] = array('ico_php.png', 'Arquivo PHP');

foreach ($items as $item)
{
    $imagem = $item[0];
    $texto  = $item[1];
    
    $pixbuf = GdkPixbuf::new_from_file($imagem);
    
    $iter = $model->append(array($pixbuf, $texto));
}

$comboBox->set_active(0);
$window->add($comboBox);

$window->show_all();
Gtk::main();
?>
