## 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 GtkOptionMenu, or similar to a Windows-style combo box.

Unlike its predecessors GtkCombo and GtkOptionMenu, 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.

In addition to the model-view API, GtkComboBox 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 functions `gtk_combo_box_new_text()`, `gtk_combo_box_append_text()`, `gtk_combo_box_insert_text()`, `gtk_combo_box_prepend_text()`, `gtk_combo_box_remove_text()` and `gtk_combo_box_get_active_text()`.
