public interface TreeSortable : Object, TreeModel

TreeSortable is an interface to be implemented by tree models which support sorting.

The TreeView uses the methods provided by this interface to sort the model.

All known implementing classes:

Namespace: Gtk

Package: gtk+-3.0

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.
public abstract bool has_default_sort_func ()
Returns true if the model has a default sort function.
public abstract void set_default_sort_func (owned TreeIterCompareFunc sort_func)
Sets the default comparison function used when sorting to be sort_func.
public abstract void set_sort_column_id (int sort_column_id, SortType order)
Sets the current sort column to be sort_column_id.
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.

public virtual signal void sort_column_changed ()
The sort_column_changed signal is emitted when the sort column or sort order of sortable is changed.
