+ * @Short_description: Renders a combobox in a cell
+ * @Title: GtkCellRendererCombo
+ *
+ * #GtkCellRendererCombo renders text in a cell like #GtkCellRendererText from
+ * which it is derived. But while #GtkCellRendererText offers a simple entry to
+ * edit the text, #GtkCellRendererCombo offers a #GtkComboBox
+ * widget to edit the text. The values to display in the combo box are taken from
+ * the tree model specified in the #GtkCellRendererCombo:model property.
+ *
+ * The combo cell renderer takes care of adding a text cell renderer to the combo
+ * box and sets it to display the column specified by its
+ * #GtkCellRendererCombo:text-column property. Further properties of the combo box
+ * can be set in a handler for the #GtkCellRenderer::editing-started signal.
+ *
+ * The #GtkCellRendererCombo cell renderer was added in GTK+ 2.6.
