A cell area that renders GtkCellRenderers into a row or a column
List views use widgets for displaying their contents
The `GtkCellAreaBox` renders cell renderers into a row or a column depending on its `GtkOrientation`.
GtkCellAreaBox uses a notion of packing. Packing refers to adding cell renderers with reference to a particular position in a `GtkCellAreaBox`. There are two reference positions: the start and the end of the box. When the `GtkCellAreaBox` is oriented in the gtk_orientation_vertical orientation, the start is defined as the top of the box and the end is defined as the bottom. In the gtk_orientation_horizontal orientation start is defined as the left side and the end is defined as the right side.
Alignments of `GtkCellRenderer`s rendered in adjacent rows can be configured by configuring the `GtkCellAreaBox` align child cell property with cell_set_property or by specifying the "align" argument to pack_start_full and pack_end_full.
