# Method GTK2.TreeViewColumn()->set_sort_order()

Method set_sort_order

  ``GTK2.TreeViewColumn` set_sort_order(`int` `order`)`

Description

  Changes the appearance of the sort indicator.

  This does not actually sort the model. Use set_sort_column_id() if you wnat automatic sorting support. This function is primarily for custom sorting behavior, and should be used in conjunction with GTK2.TreeSortable->set_sort_column() to do that. For custom models, the mechanism will vary.

  The sort indicator changes direction to indicate normal sort or reverse sort. Note that you must have the sort indicator enabled to see anything when calling this function. One of SORT_ASCENDING and SORT_DESCENDING.
