gtk:cell-area-preferred-height (area context widget)

area -- a gtk:cell-area object
context -- a gtk:cell-area-context object to perform this request with
widget -- a gtk:widget where area will be rendering
minimum-height -- an integer for the minimum height, or nil
natural-height -- an integer for the natural height, or nil

Retrieves an initial minimum and natural height of the cell area. The area argument will store some geometrical information in context along the way, when requesting sizes over an arbitrary number of rows, its not important to check the minimum-height and natural-height of this call but rather to consult the gtk:cell-area-context-preferred-height function after a series of requests.
