Implemented Interfaces

GtkComboBox implements AtkImplementorIface, GtkBuildable, GtkCellLayout and GtkCellEditable.

Includes

#include <gtk/gtk.h>

Description

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 GtkCellLayout 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 GtkEntry. This entry can be accessed by calling gtk_bin_get_child() 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, GtkComboBoxText offers a simple alternative. Both GtkComboBox and GtkComboBoxText can contain an entry.
