+ * @Short_description: A widget displaying a single row of a GtkTreeModel
+ * @Title: GtkCellView
+ *
+ * A #GtkCellView displays a single row of a #GtkTreeModel using a #GtkCellArea
+ * and #GtkCellAreaContext. A #GtkCellAreaContext can be provided to the
+ * #GtkCellView at construction time in order to keep the cellview in context
+ * of a group of cell views, this ensures that the renderers displayed will
+ * be properly aligned with eachother (like the aligned cells in the menus
+ * of #GtkComboBox).
+ *
+ * #GtkCellView is #GtkOrientable in order to decide in which orientation
+ * the underlying #GtkCellAreaContext should be allocated. Taking the #GtkComboBox
+ * menu as an example, cellviews should be oriented horizontally if the menus are
+ * listed top-to-bottom and thus all share the same width but may have separate
+ * individual heights (left-to-right menus should be allocated vertically since
+ * they all share the same height but may have variable widths).
