## Member Function Documentation

void Gtk::TreeModelSort::clear_cache | ( |  | ) |

| 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.

iterator Gtk::TreeModelSort::convert_child_iter_to_iter | ( | const iterator& | child_iter | ) | const

TreeModel::Path Gtk::TreeModelSort::convert_child_path_to_path | ( | const Path& | child_path | ) | const

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 `0` is returned.

Parameters:

  child_path | A Gtk::TreePath to convert.

Returns:
  A newly allocated Gtk::TreePath, or `0`.

iterator Gtk::TreeModelSort::convert_iter_to_child_iter | ( | const iterator& | sorted_iter | ) | const

TreeModel::Path Gtk::TreeModelSort::convert_path_to_child_path | ( | const Path& | sorted_path | ) | const

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, `0` is returned.

Parameters:

  sorted_path | A Gtk::TreePath to convert.

Returns:
  A newly allocated Gtk::TreePath, or `0`.

Glib::RefPtr<TreeModelSort> Gtk::TreeModelSort::create | ( | const Glib::RefPtr<TreeModel>& | model | ) | `[static]`

Glib::RefPtr<const TreeModel> Gtk::TreeModelSort::get_model | ( |  | ) | const

Returns the model the Gtk::TreeModelSort is sorting.

Returns:
  The "child model" being sorted.

Glib::RefPtr<TreeModel> Gtk::TreeModelSort::get_model | ( |  | ) |

Returns the model the Gtk::TreeModelSort is sorting.

Returns:
  The "child model" being sorted.

const GtkTreeModelSort* Gtk::TreeModelSort::gobj | ( |  | ) | const`[inline]`

| Provides access to the underlying C GObject. Reimplemented from Gtk::TreeModel.

GtkTreeModelSort* Gtk::TreeModelSort::gobj | ( |  | ) | `[inline]`

| Provides access to the underlying C GObject. Reimplemented from Gtk::TreeModel.

GtkTreeModelSort* Gtk::TreeModelSort::gobj_copy | ( |  | ) |

bool Gtk::TreeModelSort::iter_is_valid | ( | const iterator& | iter | ) | const

WARNING: This function is slow.

Only use it for debugging and/or testing purposes.

Checks if the given iter is a valid iter for this Gtk::TreeModelSort.

Parameters:

  iter | A Gtk::TreeIter.

Returns:
  `true` if the iter is valid, `false` if the iter is invalid.

Since: 2.2.

void Gtk::TreeModelSort::reset_default_sort_func | ( |  | ) |

| 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 Gtk::TreeModelSort is in 'unsorted' state.

virtual void Gtk::TreeModelSort::set_value_impl | ( | const iterator& | row,
|  | int | column,
|  | const Glib::ValueBase& | value
| ) | `[protected, virtual]`

| Reimplemented from Gtk::TreeModel.
