GI.Gtk.Objects.ComboBox

A GtkComboBox is a widget that allows the user to choose from a list of valid choices. The GtkComboBox displays the selected choice. When activated, the GtkComboBox displays a popup which allows the user to make a new choice. The style in which the selected value is displayed, and the style of the popup is determined by the current theme. It may be similar to a Windows-style combo box.

The GtkComboBox 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 GtkComboBox implements the 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.

To allow the user to enter values not in the model, the “has-entry” property allows the GtkComboBox to contain a Entry. This entry can be accessed by calling binGetChild on the combo box.

For a simple list of textual choices, the model-view API of GtkComboBox can be a bit overwhelming. In this case, ComboBoxText offers a simple alternative. Both GtkComboBox and ComboBoxText can contain an entry.

A GtkComboBox with an entry has a single CSS node with name combobox. It contains a box with the .linked class. That box contains an entry and a button, both with the .combo class added. The button also contains another node with name arrow.

Signals

changed

type ComboBoxChangedCallback = IO ()

The changed signal is emitted when the active item is changed. The can be due to the user selecting a different item from the list, or due to a call to comboBoxSetActiveIter. It will also be emitted while typing into the entry of a combo box with an entry.

Since: 2.4

Connect a signal handler for the changed signal, to be run after the default handler. When overloading is enabled, this is equivalent to

after comboBox #changed callback

By default the object invoking the signal is not passed to the callback. If you need to access it, you can use the implit ?self parameter. Note that this requires activating the ImplicitParams GHC extension.

onComboBoxChanged :: (IsComboBox a, MonadIO m) => a -> ((?self :: a) => ComboBoxChangedCallback) -> m SignalHandlerId

Connect a signal handler for the changed signal, to be run before the default handler. When overloading is enabled, this is equivalent to

on comboBox #changed callback

formatEntryText

type ComboBoxFormatEntryTextCallback

Arguments

 = Text

path: the GtkTreePath string from the combo box's current model to format text for

-> IO Text

Returns: a newly allocated string representing path for the current GtkComboBox model.

For combo boxes that are created with an entry (See GtkComboBox:has-entry).

A signal which allows you to change how the text displayed in a combo box's entry is displayed.

Connect a signal handler which returns an allocated string representing path. That string will then be used to set the text in the combo box's entry. The default signal handler uses the text from the GtkComboBoxentryTextColumn model column.

Here's an example signal handler which fetches data from the model and displays it in the entry.

C code

static gchar*
format_entry_text_callback (GtkComboBox *combo,
                            const gchar *path,
                            gpointer     user_data)
{
  GtkTreeIter iter;
  GtkTreeModel model;
  gdouble      value;

  model = gtk_combo_box_get_model (combo);

  gtk_tree_model_get_iter_from_string (model, &iter, path);
  gtk_tree_model_get (model, &iter,
                      THE_DOUBLE_VALUE_COLUMN, &value,
