+ * (relative to the tree view model)
+ * @new_iter: the new iter selected in the combo box
+ * (relative to the combo box model)
+ *
+ * This signal is emitted each time after the user selected an item in
+ * the combo box, either by using the mouse or the arrow keys. Contrary
+ * to GtkComboBox, GtkCellRendererCombo::changed is not emitted for
+ * changes made to a selected item in the entry. The argument @new_iter
+ * corresponds to the newly selected item in the combo box and it is relative
+ * to the GtkTreeModel set via the model property on GtkCellRendererCombo.
+ *
+ * Note that as soon as you change the model displayed in the tree view,
+ * the tree view will immediately cease the editing operating. This
+ * means that you most probably want to refrain from changing the model
+ * until the combo cell renderer emits the edited or editing_canceled signal.
