TreeSortable.setSortColumnId

void setSortColumnId(int sortColumnId, gtk.types.SortType order)

Sets the current sort column to be sort_column_id. The sortable will resort itself to reflect this change, after emitting a GtkTreeSortable::sort-column-changed signal. sort_column_id may either be a regular column id, or one of the following special values:

[gtk.types.TREE_SORTABLE_DEFAULT_SORT_COLUMN_ID]: the default sort function

will be used, if it is set

[gtk.types.TREE_SORTABLE_UNSORTED_SORT_COLUMN_ID]: no sorting will occur

Parameters

`sortColumnId`	the sort column id to set
`order`	The sort order of the column
