$title->set_size_request(-1, 60);
$vbox->pack_start($title, 0, 0);
// the selection
$list = array('item 1', 'item 2', 'item 3', 'item 4');
$vbox->pack_start($hbox=new GtkHBox(), 0, 0);
$hbox->pack_start(new GtkLabel('Select: '), 0, 0);
// Create the data model
if (defined("GObject::TYPE_STRING")) {
$model = new GtkListStore(GObject::TYPE_STRING); // note 1
} else {
$model = new GtkListStore(Gtk::TYPE_STRING); // note 1
}
// Create the comboboxentry
$combobox = &GtkComboBoxEntry::new_with_model($model, 0); // note 2
// Stuff the choices in the model
foreach($list as $choice) {
$model->append(array($choice));
}
// Set up a hbox to contain the combobox as well as the Submit button
$hbox->pack_start($combobox, 0, 0);
