       Gtk2::ComboBox - A widget used to choose from a list of items

	 # the easy way:
	 $combobox = Gtk2::ComboBox->new_text;
	 foreach (@strings) {
	     $combobox->append_text ($_);
	 $combobox->prepend_text ($another_string);
	 $combobox->insert_text ($index, $yet_another_string);
	 $combobox->remove_text ($index);
	 $text = $combobox->get_active_text;

	 # the full-featured way.
	 # a combo box that shows stock ids and their images:
	 use constant ID_COLUMN => 0;
	 $model = Gtk2::ListStore->new ('Glib::String');
	 foreach (qw(gtk-ok gtk-cancel gtk-yes gtk-no gtk-save gtk-open)) {
	     $model->set ($model->append, ID_COLUMN, $_);
	 $combo_box = Gtk2::ComboBox->new ($model);
	 # to display anything, you must pack cell renderers into
	 # the combobox, which implements the Gtk2::CellLayout interface.
	 $renderer = Gtk2::CellRendererPixbuf->new;
	 $combo_box->pack_start ($renderer, FALSE);
	 $combo_box->add_attribute ($renderer, stock_id => ID_COLUMN);
	 $renderer = Gtk2::CellRendererText->new;
	 $combo_box->pack_start ($renderer, TRUE);
	 $combo_box->add_attribute ($renderer, text => ID_COLUMN);

	 # select by index
	 $combo_box->set_active ($index);
	 $active_index = $combo_box->get_active;

	 # or by iter
	 $combo_box->set_active_iter ($iter);
	 $active_iter = $combo_box->get_active_iter;

       Gtk2::ComboBox is a widget that allows the user to choose from a list of valid choices.
       The ComboBox displays the selected choice.  When activated, the ComboBox displays a popup
       which allows the user to make a new choice.

       Unlike its predecessors Gtk2::Combo and Gtk2::OptionMenu, the Gtk2::ComboBox uses the
       model-view pattern; the list of valid choices is specified in the form of a tree model,
       and the display of the choices can be adapted to the data in the model by using cell
       renderers, as you would in a tree view.	This is possible since ComboBox implements the
       Gtk2::CellLayout interface.  The tree model holding the valid choices is not restricted to
       a flat list; it can be a real tree, and the popup will reflect the tree structure.

       In addition to the model-view API, ComboBox offers a simple API which is suitable for
       text-only combo boxes, and hides the complexity of managing the data in a model.  It
       consists of the methods "new_text", "append_text", "insert_text", "prepend_text",
       "remove_text" and "get_active_text".
