gtk:cell-area-context-preferred-width-for-height (context height)

context -- a gtk:cell-area-context object
height -- an integer with a proposed height for allocation

minimum -- an integer with the minimum width, or nil
natural -- an integer with the natural width, or nil

Gets the accumulative preferred width for height for all rows which have been requested for the same said height with this context. After the gtk:cell-area-context-reset function is called and/or before ever requesting the size of a cell area, the returned values are -1. The gtk:cell-area-context implementation is deprecated since 4.10. This object will be removed in GTK 5.
