gtk-cell-renderer-size (cell widget area)

cell -- a gtk-cell-renderer object
widget -- the gtk-widget object the renderer is rendering to
area -- a gdk-rectangle with the area a cell will be allocated, or nil

x-offset -- an integer with the x offset of cell relative to area, or nil
y-offset -- an integer with the y offset of cell relative to area, or nil
width -- an integer with the width needed to render a cell, or nil
height -- an integer with the height needed to render a cell, or nil

Obtains the width and height needed to render the cell. Used by tree view widgets to determine the appropriate size for the cell area passed to the function gtk-cell-renderer-render. If area is not nil, fills in the x and y offsets (if set) of the cell relative to this location.

Please note that the values set in width and height, as well as those in x-offset and y-offset are inclusive of the xpad and ypad properties. The gtk-cell-renderer-size function has been deprecated since version 3.0 and should not be used in newly written code. Use the gtk-cell-renderer-preferred-size function instead.
