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".
