Detailed Description
A cell area that renders CellRenderers into a row or a colum, depending on its orientation.
This class uses a notion of packing. Packing refers to adding cell renderers with reference to a particular position in a CellAreaBox . There are two reference positions: the start and the end of the box. When the CellAreaBox 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 CellRenderers rendered in adjacent rows can be configured by configuring the align_child cell property with CellArea::cell_set_property() or by specifying the "align" argument to pack_start() or pack_end() .
