TreeViewColumn.setCellDataFunc

void setCellDataFunc(gtk.cell_renderer.CellRenderer cellRenderer, gtk.types.TreeCellDataFunc func = null)

Sets the #GtkTreeCellDataFunc to use for the column. This function is used instead of the standard attributes mapping for setting the column value, and should set the value of tree_column's cell renderer as appropriate. func may be null to remove an older one.

Parameters

`cellRenderer`	A #GtkCellRenderer
`func`	The #GtkTreeCellDataFunc to use.
