32 * SECTION:ctktreemodelsort
33 * @Short_description: A CtkTreeModel which makes an underlying tree model sortable
34 * @Title: CtkTreeModelSort
35 * @See_also: #CtkTreeModel, #CtkListStore, #CtkTreeStore, #CtkTreeSortable, #CtkTreeModelFilter
36 *
37 * The #CtkTreeModelSort is a model which implements the #CtkTreeSortable
38 * interface. It does not hold any data itself, but rather is created with
39 * a child model and proxies its data. It has identical column types to
40 * this child model, and the changes in the child are propagated. The
41 * primary purpose of this model is to provide a way to sort a different
42 * model without modifying it. Note that the sort function used by
43 * #CtkTreeModelSort is not guaranteed to be stable.
44 *
45 * The use of this is best demonstrated through an example. In the
46 * following sample code we create two #CtkTreeView widgets each with a
47 * view of the same data. As the model is wrapped here by a
48 * #CtkTreeModelSort, the two #CtkTreeViews can each sort their
49 * view of the data without affecting the other. By contrast, if we
50 * simply put the same model in each widget, then sorting the first would
51 * sort the second.
52 *
53 * ## Using a #CtkTreeModelSort
54 *
55 * |[<!-- language="C" -->
56 * {
57 * CtkTreeView *tree_view1;
58 * CtkTreeView *tree_view2;
59 * CtkTreeModel *sort_model1;
60 * CtkTreeModel *sort_model2;
61 * CtkTreeModel *child_model;
62 *
63 * // get the child model
64 * child_model = get_my_model ();
65 *
66 * // Create the first tree
67 * sort_model1 = ctk_tree_model_sort_new_with_model (child_model);
68 * tree_view1 = ctk_tree_view_new_with_model (sort_model1);
69 *
70 * // Create the second tree
71 * sort_model2 = ctk_tree_model_sort_new_with_model (child_model);
72 * tree_view2 = ctk_tree_view_new_with_model (sort_model2);
73 *
74 * // Now we can sort the two models independently
75 * ctk_tree_sortable_set_sort_column_id (CTK_TREE_SORTABLE (sort_model1),
76 * COLUMN_1, CTK_SORT_ASCENDING);
77 * ctk_tree_sortable_set_sort_column_id (CTK_TREE_SORTABLE (sort_model2),
78 * COLUMN_1, CTK_SORT_DESCENDING);
79 * }
80 * ]|
81 *
82 * To demonstrate how to access the underlying child model from the sort
83 * model, the next example will be a callback for the #CtkTreeSelection
84 * #CtkTreeSelection::changed signal. In this callback, we get a string
85 * from COLUMN_1 of the model. We then modify the string, find the same
86 * selected row on the child model, and change the row there.
87 *
88 * ## Accessing the child model of in a selection changed callback
89 *
90 * |[<!-- language="C" -->
91 * void
92 * selection_changed (CtkTreeSelection *selection, gpointer data)
93 * {
94 * CtkTreeModel *sort_model = NULL;
95 * CtkTreeModel *child_model;
96 * CtkTreeIter sort_iter;
97 * CtkTreeIter child_iter;
98 * char *some_data = NULL;
99 * char *modified_data;
100 *
101 * // Get the current selected row and the model.
102 * if (! ctk_tree_selection_get_selected (selection,
103 * &sort_model,
104 * &sort_iter))
105 * return;
106 *
107 * // Look up the current value on the selected row and get
108 * // a new value to change it to.
109 * ctk_tree_model_get (CTK_TREE_MODEL (sort_model), &sort_iter,
110 * COLUMN_1, &some_data,
111 * -1);
112 *
113 * modified_data = change_the_data (some_data);
114 * g_free (some_data);
115 *
116 * // Get an iterator on the child model, instead of the sort model.
117 * ctk_tree_model_sort_convert_iter_to_child_iter (CTK_TREE_MODEL_SORT (sort_model),
118 * &child_iter,
119 * &sort_iter);
120 *
121 * // Get the child model and change the value of the row. In this
122 * // example, the child model is a CtkListStore. It could be any other
123 * // type of model, though.
124 * child_model = ctk_tree_model_sort_get_model (CTK_TREE_MODEL_SORT (sort_model));
125 * ctk_list_store_set (CTK_LIST_STORE (child_model), &child_iter,

134/* Notes on this implementation of CtkTreeModelSort
135 * ================================================
136 *
137 * Warnings
138 * --------
139 *
140 * In this code there is a potential for confusion as to whether an iter,
141 * path or value refers to the CtkTreeModelSort model, or to the child model
142 * that has been set. As a convention, variables referencing the child model
143 * will have an s_ prefix before them (ie. s_iter, s_value, s_path);
144 * Conversion of iterators and paths between CtkTreeModelSort and the child
145 * model is done through the various ctk_tree_model_sort_convert_* functions.
146 *
147 * Iterator format
148 * ---------------
149 *
150 * The iterator format of iterators handed out by CtkTreeModelSort is as
151 * follows:
152 *
153 * iter->stamp = tree_model_sort->stamp
154 * iter->user_data = SortLevel
155 * iter->user_data2 = SortElt
156 *
157 * Internal data structure
158 * -----------------------
159 *
160 * Using SortLevel and SortElt, CtkTreeModelSort maintains a “cache” of
161 * the mapping from CtkTreeModelSort nodes to nodes in the child model.
162 * This is to avoid sorting a level each time an operation is requested
163 * on CtkTreeModelSort, such as get iter, get path, get value.
164 *
165 * A SortElt corresponds to a single node. A node and its siblings are
166 * stored in a SortLevel. The SortLevel keeps a reference to the parent
167 * SortElt and its SortLevel (if any). The SortElt can have a "children"
168 * pointer set, which points at a child level (a sub level).
169 *
170 * In a SortLevel, nodes are stored in a GSequence. The GSequence
171 * allows for fast additions and removals, and supports sorting
172 * the level of SortElt nodes.
173 *
174 * It is important to recognize the two different mappings that play
175 * a part in this code:
176 * I. The mapping from the client to this model. The order in which
177 * nodes are stored in the GSequence is the order in which the
178 * nodes are exposed to clients of the CtkTreeModelSort.
179 * II. The mapping from this model to its child model. Each SortElt
180 * contains an “offset” field which is the offset of the
181 * corresponding node in the child model.
182 *
183 * Reference counting
184 * ------------------
185 *
186 * CtkTreeModelSort forwards all reference and unreference operations
187 * to the corresponding node in the child model. The reference count
188 * of each node is also maintained internally, in the “ref_count”
189 * fields in SortElt and SortLevel. For each ref and unref operation on
190 * a SortElt, the “ref_count” of the SortLevel is updated accordingly.
191 * In addition, if a SortLevel has a parent, a reference is taken on
192 * this parent. This happens in ctk_tree_model_sort_build_level() and
193 * the reference is released again in ctk_tree_model_sort_free_level().
194 * This ensures that when CtkTreeModelSort takes a reference on a node
195 * (for example during sorting), all parent nodes are referenced
196 * according to reference counting rule 1, see the CtkTreeModel
197 * documentation.
198 *
199 * When a level has a reference count of zero, which means that
200 * none of the nodes in the level is referenced, the level has
201 * a “zero ref count” on all its parents. As soon as the level
202 * reaches a reference count of zero, the zero ref count value is
203 * incremented by one on all parents of this level. Similarly, as
204 * soon as the reference count of a level changes from zero, the
205 * zero ref count value is decremented by one on all parents.
206 *
207 * The zero ref count value is used to clear unused portions of
208 * the cache. If a SortElt has a zero ref count of one, then
209 * its child level is unused and can be removed from the cache.
210 * If the zero ref count value is higher than one, then the
211 * child level contains sublevels which are unused as well.
212 * ctk_tree_model_sort_clear_cache() uses this to not recurse
213 * into levels which have a zero ref count of zero.
