Methods:

• public abstract bool get_sort_column_id (out int sort_column_id, out SortType order)
  Fills in sort_column_id and order with the current sort column and the order. It returns true unless the sort_column_id is DEFAULT or UNSORTED.
• public abstract bool has_default_sort_func ()
  Returns true if the model has a default sort function. This is used primarily by GtkTreeViewColumns in order to determine if a model can go back to the default state, or not.
• public abstract void set_default_sort_func (owned TreeIterCompareFunc sort_func)
  Sets the default comparison function used when sorting to be sort_func. If the current sort column id of sortable is DEFAULT, then the model will sort using this function.
• public abstract void set_sort_column_id (int sort_column_id, SortType order)
• public abstract void set_sort_func (int sort_column_id, owned TreeIterCompareFunc sort_func)
  Sets the comparison function used when sorting to be sort_func. If the current sort column id of sortable is the same as sort_column_id, then the model will sort using this function.

Signals:

• public void sort_column_changed ()
  The sort_column_changed signal is emitted when the sort column or sort order of sortable is changed. The signal is emitted before the contents of sortable are resorted.
