Retrieves a cell area’s minimum and natural width if it would be given the specified height
.
this stores some geometrical information in context
along the way while calling
get_preferred_height. It’s important to perform a series of
get_preferred_height requests with context
first
and then call get_preferred_width_for_height on each cell area individually to get the height for
width of each fully requested row.
If at some point, the height of a single row changes, it should be requested with get_preferred_height again and then the full height of the requested rows checked again with get_preferred_height.
