  36  * @Short_description: A widget displaying a single row of a GtkTreeModel
  37  * @Title: GtkCellView
  38  *
  39  * A #GtkCellView displays a single row of a #GtkTreeModel using a #GtkCellArea
  40  * and #GtkCellAreaContext. A #GtkCellAreaContext can be provided to the
  41  * #GtkCellView at construction time in order to keep the cellview in context
  42  * of a group of cell views, this ensures that the renderers displayed will
  43  * be properly aligned with eachother (like the aligned cells in the menus
  44  * of #GtkComboBox).
  45  *
  46  * #GtkCellView is #GtkOrientable in order to decide in which orientation
  47  * the underlying #GtkCellAreaContext should be allocated. Taking the #GtkComboBox
  48  * menu as an example, cellviews should be oriented horizontally if the menus are
  49  * listed top-to-bottom and thus all share the same width but may have separate
  50  * individual heights (left-to-right menus should be allocated vertically since
  51  * they all share the same height but may have variable widths).
