Detailed Description

This stores geometrical information for a series of rows in a CellArea.

CellAreaContext is used by widgets such as TreeView and IconView, but application developers do not usually need to be aware of it.

The CellAreaContext object is created by a given CellArea and is used to store cell sizes and alignments for a series of TreeModel rows that are requested and rendered in the same context.

CellLayout widgets can create any number of contexts in which to request and render groups of data rows. However. it's important that the same context which was used to request sizes for a given TreeModel row also be used for the same row when calling other CellArea APIs such as gtk_cell_area_render() and gtk_cell_area_event().
