GtkTreeModelSort implements GtkTreeModel, GtkTreeSortable and GtkTreeDragSource.
GtkTreeModel *
gtk_tree_model_sort_new_with_model (GtkTreeModel *child_model);
Creates a new GtkTreeModel, with child_model
 as the child model.
GtkTreeModel *
gtk_tree_model_sort_get_model (GtkTreeModelSort *tree_model);
Returns the model the GtkTreeModelSort is sorting.
GtkTreePath * gtk_tree_model_sort_convert_child_path_to_path (GtkTreeModelSort *tree_model_sort,GtkTreePath *child_path);
Converts child_path
 to a path relative to tree_model_sort
.  That is,
child_path
 points to a path in the child model.  The returned path will
point to the same row in the sorted model.  If child_path
 isn't a valid 
path on the child model, then NULL is returned.
gboolean gtk_tree_model_sort_convert_child_iter_to_iter (GtkTreeModelSort *tree_model_sort,GtkTreeIter *sort_iter,GtkTreeIter *child_iter);
Sets sort_iter
 to point to the row in tree_model_sort
 that corresponds to
the row pointed at by child_iter
.  If sort_iter
 was not set, FALSE
is returned.  Note: a boolean is only returned since 2.14.
| tree_model_sort | ||
| sort_iter | An uninitialized GtkTreeIter. | [out] | 
| child_iter | A valid GtkTreeIter pointing to a row on the child model | 
GtkTreePath * gtk_tree_model_sort_convert_path_to_child_path (GtkTreeModelSort *tree_model_sort,GtkTreePath *sorted_path);
Converts sorted_path
 to a path on the child model of tree_model_sort
.  
That is, sorted_path
 points to a location in tree_model_sort
.  The 
returned path will point to the same location in the model not being 
sorted.  If sorted_path
 does not point to a location in the child model, 
NULL is returned.
void gtk_tree_model_sort_convert_iter_to_child_iter (GtkTreeModelSort *tree_model_sort,GtkTreeIter *child_iter,GtkTreeIter *sorted_iter);
Sets child_iter
 to point to the row pointed to by sorted_iter
.

| child_iter | An uninitialized GtkTreeIter. | [out] | 
| sorted_iter | A valid GtkTreeIter pointing to a row on  | 
void
gtk_tree_model_sort_reset_default_sort_func
                               (GtkTreeModelSort *tree_model_sort);
This resets the default sort function to be in the 'unsorted' state. That is, it is in the same order as the child model. It will re-sort the model to be in the same order as the child model only if the GtkTreeModelSort is in 'unsorted' state.
void
gtk_tree_model_sort_clear_cache (GtkTreeModelSort *tree_model_sort);
This function should almost never be called.  It clears the tree_model_sort
of any cached iterators that haven't been reffed with
gtk_tree_model_ref_node().  This might be useful if the child model being
sorted is static (and doesn't change often) and there has been a lot of
unreffed access to nodes.  As a side effect of this function, all unreffed
iters will be invalid.
gboolean gtk_tree_model_sort_iter_is_valid (GtkTreeModelSort *tree_model_sort,GtkTreeIter *iter);
This function is slow. Only use it for debugging and/or testing purposes.
Checks if the given iter is a valid iter for this GtkTreeModelSort.
Since: 2.2
