9 # the easy way:
10 $combobox = Gtk2::ComboBox->new_text;
11 foreach (@strings) {
12 $combobox->append_text ($_);
13 }
14 $combobox->prepend_text ($another_string);
15 $combobox->insert_text ($index, $yet_another_string);
16 $combobox->remove_text ($index);
17 $text = $combobox->get_active_text;
18 # the full-featured way.
21 # a combo box that shows stock ids and their images:
22 use constant ID_COLUMN => 0;
23 $model = Gtk2::ListStore->new ('Glib::String');
24 foreach (qw(gtk-ok gtk-cancel gtk-yes gtk-no gtk-save gtk-open)) {
25 $model->set ($model->append, ID_COLUMN, $_);
26 }
27 $combo_box = Gtk2::ComboBox->new ($model);
28 # to display anything, you must pack cell renderers into
29 # the combobox, which implements the Gtk2::CellLayout interface.
30 $renderer = Gtk2::CellRendererPixbuf->new;
31 $combo_box->pack_start ($renderer, FALSE);
32 $combo_box->add_attribute ($renderer, stock_id => ID_COLUMN);
33 $renderer = Gtk2::CellRendererText->new;
34 $combo_box->pack_start ($renderer, TRUE);
35 $combo_box->add_attribute ($renderer, text => ID_COLUMN);
36 # select by index
38 $combo_box->set_active ($index);
39 $active_index = $combo_box->get_active;
40 # or by iter
42 $combo_box->set_active_iter ($iter);
43 $active_iter = $combo_box->get_active_iter;

46 Gtk2::ComboBox is a widget that allows the user to choose from a list
47 of valid choices. The ComboBox displays the selected choice. When
48 activated, the ComboBox displays a popup which allows the user to make
49 a new choice.
50 Unlike its predecessors Gtk2::Combo and Gtk2::OptionMenu, the
52 Gtk2::ComboBox uses the model-view pattern; the list of valid choices
53 is specified in the form of a tree model, and the display of the
54 choices can be adapted to the data in the model by using cell
55 renderers, as you would in a tree view. This is possible since
56 ComboBox implements the Gtk2::CellLayout interface. The tree model
57 holding the valid choices is not restricted to a flat list; it can be a
58 real tree, and the popup will reflect the tree structure.
59 In addition to the model-view API, ComboBox offers a simple API which
61 is suitable for text-only combo boxes, and hides the complexity of
62 managing the data in a model. It consists of the methods "new_text",
63 "append_text", "insert_text", "prepend_text", "remove_text" and
64 "get_active_text".
