Implemented Interfaces

GtkComboBoxText implements AtkImplementorIface, GtkBuildable, GtkCellLayout and GtkCellEditable.

Includes

#include <gtk/gtk.h>

Description

A GtkComboBoxText is a simple variant of GtkComboBox that hides the model-view complexity for simple text-only use cases.

To create a GtkComboBoxText, use gtk_combo_box_text_new() or gtk_combo_box_text_new_with_entry().

You can add items to a GtkComboBoxText with gtk_combo_box_text_append_text(), gtk_combo_box_text_insert_text() or gtk_combo_box_text_prepend_text() and remove options with gtk_combo_box_text_remove().

If the GtkComboBoxText contains an entry (via the “has-entry” property), its contents can be retrieved using gtk_combo_box_text_get_active_text(). The entry itself can be accessed by calling gtk_bin_get_child() on the combo box.

You should not call gtk_combo_box_set_model() or attempt to pack more cells into this combo box via its GtkCellLayout interface.

GtkComboBoxText as GtkBuildable

The GtkComboBoxText implementation of the GtkBuildable interface supports adding items directly using the <items> element and specifying <item> elements for each item. Each <item> element can specify the “id” corresponding to the appended text and also supports the regular translation attributes “translatable”, “context” and “comments”.

Here is a UI definition fragment specifying GtkComboBoxText items:

CSS nodes

<object class="GtkComboBoxText">
  <items>
    <item translatable="yes" id="factory">Factory</item>
    <item translatable="yes" id="home">Home</item>
    <item translatable="yes" id="subway">Subway</item>
  </items>
</object>

GtkComboBoxText has a single CSS node with name combobox. It adds the style class .combo to the main CSS nodes of its entry and button children, and the .linked class to the node of its internal box.

Functions

gtk_combo_box_text_new ()

GtkWidget *
gtk_combo_box_text_new (void);

Creates a new GtkComboBoxText, which is a GtkComboBox just displaying strings.

Returns

A new GtkComboBoxText

Since: 2.24

gtk_combo_box_text_new_with_entry ()

GtkWidget *
gtk_combo_box_text_new_with_entry (void);

Creates a new GtkComboBoxText, which is a GtkComboBox just displaying strings. The combo box created by this function has an entry.

gtk_combo_box_text_append ()

void
gtk_combo_box_text_append (GtkComboBoxText *combo_box,
                           const gchar *id,
