Details

The gtk:cell-area-context object is created by a given gtk:cell-area implementation via its create_context() virtual method and is used to store cell sizes and alignments for a series of gtk:tree-model rows that are requested and rendered in the same context.

The gtk:cell-layout widget can create any number of contexts in which to request and render groups of data rows. However its important that the same context which was used to request sizes for a given gtk:tree-model row also be used for the same row when calling other gtk:cell-area APIs such as the gtk:cell-renderer-* and gtk:cell-area-event functions.
