+ * @Short_description: A widget used to choose from a list of items
+ * @Title: GtkComboBox
+ * @See_also: #GtkComboBoxText, #GtkTreeModel, #GtkCellRenderer
+ *
+ * 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.
+ *
+ * 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.
