this function.Usage

The comparison function

User data to pass to sort.func, or NULL. [ allow-none ] Details
If sort.func is NULL, then there will be no default comparison function.

default state. In this case, when the current sort column id of sortable
is GTK_TREE_SORTABLE_DEFAULT_SORT_COLUMN_ID, the model will be unsorted.
