gtk-tree-view-column-set-cell-data-func (column renderer func)

column -- a gtk-tree-view-column object
renderer -- a gtk-cell-renderer object
func -- the gtk-tree-cell-data-func callback to use

Sets the callback function to use for the tree view column. This function is used instead of the standard attributes mapping for setting the column value, and should set the value of the tree view column cell renderer as appropriate. func may be nil to remove an older one.
