24 * SECTION:ctkcellareabox
25 * @Short_Description: A cell area that renders CtkCellRenderers
26 * into a row or a column
27 * @Title: CtkCellAreaBox
28 *
29 * The #CtkCellAreaBox renders cell renderers into a row or a column
30 * depending on its #CtkOrientation.
31 *
32 * CtkCellAreaBox uses a notion of packing. Packing
33 * refers to adding cell renderers with reference to a particular position
34 * in a #CtkCellAreaBox. There are two reference positions: the
35 * start and the end of the box.
36 * When the #CtkCellAreaBox is oriented in the %CTK_ORIENTATION_VERTICAL
37 * orientation, the start is defined as the top of the box and the end is
38 * defined as the bottom. In the %CTK_ORIENTATION_HORIZONTAL orientation
39 * start is defined as the left side and the end is defined as the right
40 * side.
41 *
42 * Alignments of #CtkCellRenderers rendered in adjacent rows can be
43 * configured by configuring the #CtkCellAreaBox align child cell property
44 * with ctk_cell_area_cell_set_property() or by specifying the "align"
45 * argument to ctk_cell_area_box_pack_start() and ctk_cell_area_box_pack_end().
