| 32 | * @Title: CtkTreeModel | |||
| 33 | * @Short_description: The tree interface used by CtkTreeView | |||
| 34 | * @See_also: #CtkTreeView, #CtkTreeStore, #CtkListStore, | |||
| 35 | * [CtkTreeView drag-and-drop][ctk3-CtkTreeView-drag-and-drop] | |||
| 36 | * #CtkTreeSortable | |||
| 37 | * | |||
| 38 | * The #CtkTreeModel interface defines a generic tree interface for | |||
| 39 | * use by the #CtkTreeView widget. It is an abstract interface, and | |||
| 40 | * is designed to be usable with any appropriate data structure. The | |||
| 41 | * programmer just has to implement this interface on their own data | |||
| 42 | * type for it to be viewable by a #CtkTreeView widget. | |||
| 43 | * | |||
| 44 | * The model is represented as a hierarchical tree of strongly-typed, | |||
| 45 | * columned data. In other words, the model can be seen as a tree where | |||
| 46 | * every node has different values depending on which column is being | |||
| 47 | * queried. The type of data found in a column is determined by using | |||
| 48 | * the GType system (ie. #G_TYPE_INT, #CTK_TYPE_BUTTON, #G_TYPE_POINTER, | |||
| 49 | * etc). The types are homogeneous per column across all nodes. It is | |||
| 50 | * important to note that this interface only provides a way of examining | |||
| 51 | * a model and observing changes. The implementation of each individual | |||
| 52 | * model decides how and if changes are made. | |||
| 53 | * | |||
| 54 | * In order to make life simpler for programmers who do not need to | |||
| 55 | * write their own specialized model, two generic models are provided | |||
| 56 | * — the #CtkTreeStore and the #CtkListStore. To use these, the | |||
| 57 | * developer simply pushes data into these models as necessary. These | |||
| 58 | * models provide the data structure as well as all appropriate tree | |||
| 59 | * interfaces. As a result, implementing drag and drop, sorting, and | |||
| 60 | * storing data is trivial. For the vast majority of trees and lists, | |||
| 61 | * these two models are sufficient. | |||
| 62 | * | |||
| 63 | * Models are accessed on a node/column level of granularity. One can | |||
| 64 | * query for the value of a model at a certain node and a certain | |||
| 65 | * column on that node. There are two structures used to reference a | |||
| 66 | * particular node in a model. They are the #CtkTreePath-struct and | |||
| 67 | * the #CtkTreeIter-struct (“iter” is short for iterator). Most of the | |||
| 68 | * interface consists of operations on a #CtkTreeIter-struct. | |||
| 69 | * | |||
| 70 | * A path is essentially a potential node. It is a location on a model | |||
| 71 | * that may or may not actually correspond to a node on a specific | |||
| 72 | * model. The #CtkTreePath-struct can be converted into either an | |||
| 73 | * array of unsigned integers or a string. The string form is a list | |||
| 74 | * of numbers separated by a colon. Each number refers to the offset | |||
| 75 | * at that level. Thus, the path `0` refers to the root | |||
| 76 | * node and the path `2:4` refers to the fifth child of | |||
| 77 | * the third node. | |||
| 78 | * | |||
| 79 | * By contrast, a #CtkTreeIter-struct is a reference to a specific node on | |||
| 80 | * a specific model. It is a generic struct with an integer and three | |||
| 81 | * generic pointers. These are filled in by the model in a model-specific | |||
| 82 | * way. One can convert a path to an iterator by calling | |||
| 83 | * ctk_tree_model_get_iter(). These iterators are the primary way | |||
| 84 | * of accessing a model and are similar to the iterators used by | |||
| 85 | * #CtkTextBuffer. They are generally statically allocated on the | |||
| 86 | * stack and only used for a short time. The model interface defines | |||
| 87 | * a set of operations using them for navigating the model. | |||
| 88 | * | |||
| 89 | * It is expected that models fill in the iterator with private data. | |||
| 90 | * For example, the #CtkListStore model, which is internally a simple | |||
| 91 | * linked list, stores a list node in one of the pointers. The | |||
| 92 | * #CtkTreeModelSort stores an array and an offset in two of the | |||
| 93 | * pointers. Additionally, there is an integer field. This field is | |||
| 94 | * generally filled with a unique stamp per model. This stamp is for | |||
| 95 | * catching errors resulting from using invalid iterators with a model. | |||
| 96 | * | |||
| 97 | * The lifecycle of an iterator can be a little confusing at first. | |||
| 98 | * Iterators are expected to always be valid for as long as the model | |||
| 99 | * is unchanged (and doesn’t emit a signal). The model is considered | |||
| 100 | * to own all outstanding iterators and nothing needs to be done to | |||
| 101 | * free them from the user’s point of view. Additionally, some models | |||
| 102 | * guarantee that an iterator is valid for as long as the node it refers | |||
| 103 | * to is valid (most notably the #CtkTreeStore and #CtkListStore). | |||
| 104 | * Although generally uninteresting, as one always has to allow for | |||
| 105 | * the case where iterators do not persist beyond a signal, some very | |||
| 106 | * important performance enhancements were made in the sort model. | |||
| 107 | * As a result, the #CTK_TREE_MODEL_ITERS_PERSIST flag was added to | |||
| 108 | * indicate this behavior. | |||
| 109 | * | |||
| 110 | * To help show some common operation of a model, some examples are | |||
| 111 | * provided. The first example shows three ways of getting the iter at | |||
| 112 | * the location `3:2:5`. While the first method shown is | |||
| 113 | * easier, the second is much more common, as you often get paths from | |||
| 114 | * callbacks. | |||
| 115 | * | |||
| 116 | * ## Acquiring a #CtkTreeIter-struct | |||
| 117 | * | |||
| 118 | * |[<!-- language="C" --> | |||
| 119 | * // Three ways of getting the iter pointing to the location | |||
| 120 | * CtkTreePath *path; | |||
| 121 | * CtkTreeIter iter; | |||
| 122 | * CtkTreeIter parent_iter; | |||
| 123 | * | |||
| 124 | * // get the iterator from a string | |||
| 125 | * ctk_tree_model_get_iter_from_string (model, | |||
| 126 | * &iter, | |||
| 127 | * "3:2:5"); | |||
| 128 | * | |||
| 129 | * // get the iterator from a path | |||
| 130 | * path = ctk_tree_path_new_from_string ("3:2:5"); | |||
| 131 | * ctk_tree_model_get_iter (model, &iter, path); | |||
| 132 | * ctk_tree_path_free (path); | |||
| 133 | * | |||
| 134 | * // walk the tree to find the iterator | |||
| 135 | * ctk_tree_model_iter_nth_child (model, &iter, | |||
| 136 | * NULL, 3); | |||
| 137 | * parent_iter = iter; | |||
| 138 | * ctk_tree_model_iter_nth_child (model, &iter, | |||
| 139 | * &parent_iter, 2); | |||
| 140 | * parent_iter = iter; | |||
| 141 | * ctk_tree_model_iter_nth_child (model, &iter, | |||
| 142 | * &parent_iter, 5); | |||
| 143 | * ]| | |||
| 144 | * | |||
| 145 | * This second example shows a quick way of iterating through a list | |||
| 146 | * and getting a string and an integer from each row. The | |||
| 147 | * populate_model() function used below is not | |||
| 148 | * shown, as it is specific to the #CtkListStore. For information on | |||
| 149 | * how to write such a function, see the #CtkListStore documentation. | |||
| 150 | * | |||
| 151 | * ## Reading data from a #CtkTreeModel | |||
| 152 | * | |||
| 153 | * |[<!-- language="C" --> | |||
| 154 | * enum | |||
| 155 | * { | |||
| 156 | * STRING_COLUMN, | |||
| 157 | * INT_COLUMN, | |||
| 158 | * N_COLUMNS | |||
| 159 | * }; | |||
| 160 | * | |||
| 161 | * ... | |||
| 162 | * | |||
| 163 | * CtkTreeModel *list_store; | |||
| 164 | * CtkTreeIter iter; | |||
| 165 | * gboolean valid; | |||
| 166 | * gint row_count = 0; | |||
| 167 | * | |||
| 168 | * // make a new list_store | |||
| 169 | * list_store = ctk_list_store_new (N_COLUMNS, | |||
| 170 | * G_TYPE_STRING, | |||
| 171 | * G_TYPE_INT); | |||
| 172 | * | |||
| 173 | * // Fill the list store with data | |||
| 174 | * populate_model (list_store); | |||
| 175 | * | |||
| 176 | * // Get the first iter in the list, check it is valid and walk | |||
| 177 | * // through the list, reading each row. | |||
| 178 | * | |||
| 179 | * valid = ctk_tree_model_get_iter_first (list_store, | |||
| 180 | * &iter); | |||
| 181 | * while (valid) | |||
| 182 | * { | |||
| 183 | * gchar *str_data; | |||
| 184 | * gint int_data; | |||
| 185 | * | |||
| 186 | * // Make sure you terminate calls to ctk_tree_model_get() with a “-1” value | |||
| 187 | * ctk_tree_model_get (list_store, &iter, | |||
| 188 | * STRING_COLUMN, &str_data, | |||
| 189 | * INT_COLUMN, &int_data, | |||
| 190 | * -1); | |||
| 191 | * | |||
| 192 | * // Do something with the data | |||
| 193 | * g_print ("Row %d: (%s,%d)\n", | |||
| 194 | * row_count, str_data, int_data); | |||
| 195 | * g_free (str_data); | |||
| 196 | * | |||
| 197 | * valid = ctk_tree_model_iter_next (list_store, | |||
| 198 | * &iter); | |||
| 199 | * row_count++; | |||
| 200 | * } | |||
| 201 | * ]| | |||
| 202 | * | |||
| 203 | * The #CtkTreeModel interface contains two methods for reference | |||
| 204 | * counting: ctk_tree_model_ref_node() and ctk_tree_model_unref_node(). | |||
| 205 | * These two methods are optional to implement. The reference counting | |||
| 206 | * is meant as a way for views to let models know when nodes are being | |||
| 207 | * displayed. #CtkTreeView will take a reference on a node when it is | |||
| 208 | * visible, which means the node is either in the toplevel or expanded. | |||
| 209 | * Being displayed does not mean that the node is currently directly | |||
| 210 | * visible to the user in the viewport. Based on this reference counting | |||
| 211 | * scheme a caching model, for example, can decide whether or not to cache | |||
| 212 | * a node based on the reference count. A file-system based model would | |||
| 213 | * not want to keep the entire file hierarchy in memory, but just the | |||
| 214 | * folders that are currently expanded in every current view. | |||
| 215 | * | |||
| 216 | * When working with reference counting, the following rules must be taken | |||
| 217 | * into account: | |||
| 218 | * | |||
| 219 | * - Never take a reference on a node without owning a reference on its parent. | |||
| 220 | * This means that all parent nodes of a referenced node must be referenced | |||
| 221 | * as well. | |||
| 222 | * | |||
| 223 | * - Outstanding references on a deleted node are not released. This is not | |||
| 224 | * possible because the node has already been deleted by the time the | |||
| 225 | * row-deleted signal is received. | |||
| 226 | * | |||
| 227 | * - Models are not obligated to emit a signal on rows of which none of its | |||
| 228 | * siblings are referenced. To phrase this differently, signals are only | |||
| 229 | * required for levels in which nodes are referenced. For the root level | |||
| 230 | * however, signals must be emitted at all times (however the root level | |||
| 231 | * is always referenced when any view is attached). | |||
