gtk:column-view-sort-by-column (columnview column direction)

columnview -- a gtk:column-view widget
column -- a gtk:column-view-column object to sort by, or nil
direction -- a gtk:sort-type value with the direction to sort in

Sets the sorting of the column view. This function should be used to set up the initial sorting. At runtime, users can change the sorting of a column view by clicking on the list headers.

This call only has an effect if the sorter returned by the gtk:column-view-sorter function is set on a sort model, and the (setf gtk:column-view-column-sorter) function has been called on column to associate a sorter with the column.

If column is nil, the column view will be unsorted.
