public virtual void get_preferred_height_for_width (CellAreaContext context, Widget widget, int width, out int minimum_height, out int natural_height)
Retrieves a cell area’s minimum and natural height if it would be given the specified width.
this stores some geometrical information in context along the way while calling
get_preferred_width. It’s important to perform a series of
get_preferred_width requests with context first
and then call get_preferred_height_for_width on each cell area individually to get the height for
width of each fully requested row.
If at some point, the width of a single row changes, it should be requested with get_preferred_width again and then the full width of the requested rows checked again with get_preferred_width.
