gtk-cell-area-request-renderer (area renderer orientation widget for-size)

area -- a gtk-cell-area object
renderer -- a gtk-cell-renderer object to request size for
orientation -- a value of the gtk-orientation enumeration in which to request size
widget -- a gkt-widget object that area is rendering onto
for-size -- an integer with the allocation contextual size to request for, or -1 if the base request for the orientation is to be returned

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

This is a convenience function for gtk-cell-area implementations to request size for cell renderers. It is important to use this function to request size and then use the gtk-cell-area-inner-cell-area function at render and event time since this function will add padding around the cell for focus painting.
