ListStore

A list-like data structure that can be used with the gtk.tree_view.TreeView.

The gtk.list_store.ListStore object is a list model for use with a gtk.tree_view.TreeView widget. It implements the gtk.tree_model.TreeModel interface, and consequentialy, can use all of the methods available there. It also implements the gtk.tree_sortable.TreeSortable interface so it can be sorted by the view. Finally, it also implements the tree drag and drop interfaces.

The gtk.list_store.ListStore can accept most gobject.types.TYPE_FLAG_RESERVED_ID_BITs as a column type, though it can’t accept all custom types. Internally, it will keep a copy of data passed in (such as a string or a boxed pointer). Columns that accept gobject.object.ObjectGs are handled a little differently. The gtk.list_store.ListStore will keep a reference to the object instead of copying the value. As a result, if the object is modified, it is up to the application writer to call gtk.tree_model.TreeModel.rowChanged to emit the signal@Gtk.TreeModel::row_changed signal. This most commonly affects lists with gdk.texture.Textures stored.

An example for creating a simple list store:

enum {
  COLUMN_STRING,
  COLUMN_INT,
  COLUMN_BOOLEAN,
  N_COLUMNS
};

{
  GtkListStore *list_store;
  GtkTreePath *path;
  GtkTreeIter iter;
  int i;

  list_store = gtk_list_store_new (N_COLUMNS,
                                   G_TYPE_STRING,
                                   G_TYPE_INT,
                                   G_TYPE_BOOLEAN);

  for (i = 0; i < 10; i++)
    {
      char *some_data;

      some_data = get_some_data (i);

      // Add a new row to the model
      gtk_list_store_append (list_store, &iter);
      gtk_list_store_set (list_store, &iter,
                          COLUMN_STRING, some_data,
                          COLUMN_INT, i,
                          COLUMN_BOOLEAN,  FALSE,
                          -1);

      // As the store will keep a copy of the string internally,
      // we free some_data.
      g_free (some_data);
    }

  // Modify a particular row
  path = gtk_tree_path_new_from_string ("4");
  gtk_tree_model_get_iter (GTK_TREE_MODEL (list_store),
                           &iter,
                           path);
  gtk_tree_path_free (path);
  gtk_list_store_set (list_store, &iter,
                      COLUMN_BOOLEAN, TRUE,
                      -1);
}

gtk.list_store.ListStore is deprecated since GTK 4.10, and should not be used in newly written code. You should use gio.list_store.ListStore instead, and the various list models provided by GTK.

Performance Considerations

Internally, the gtk.list_store.ListStore was originally implemented with a linked list with a tail pointer. As a result, it was fast at data insertion and deletion, and not fast at random data access. The gtk.list_store.ListStore sets the gtk.types.TreeModelFlags.ItersPersist flag, which means that gtk.tree_iter.TreeIters can be cached while the row exists. Thus, if access to a particular row is needed often and your code is expected to run on older versions of GTK, it is worth keeping the iter around.

Atomic Operations

It is important to note that only the methods gtk.list_store.ListStore.insertWithValues and gtk.list_store.ListStore.insertWithValuesv are atomic, in the sense that the row is being appended to the store and the values filled in in a single operation with regard to gtk.tree_model.TreeModel signaling. In contrast, using e.g. gtk.list_store.ListStore.append and then gtk.list_store.ListStore.set will first create a row, which triggers the GtkTreeModel::row-inserted signal on gtk.list_store.ListStore. The row, however, is still empty, and any signal handler connecting to GtkTreeModel::row-inserted on this particular store should be prepared for the situation that the row might be empty. This is especially important if you are wrapping the gtk.list_store.ListStore inside a gtk.tree_model.TreeModelFilter and are using a gtk.tree_model.TreeModelFilterVisibleFunc. Using any of the non-atomic operations to append rows to the gtk.list_store.ListStore will cause the gtk.tree_model.TreeModelFilterVisibleFunc to be visited with an empty row first; the function must be prepared for that.

GtkListStore as GtkBuildable

The GtkListStore implementation of the gtk.buildable.Buildable interface allows to specify the model columns with a <columns> element that may contain multiple <column> elements, each specifying one model column. The “type” attribute specifies the data type for the column.

Additionally, it is possible to specify content for the list store in the UI definition, with the <data> element. It can contain multiple <row> elements, each specifying to content for one row of the list model. Inside a <row>, the <col> elements specify the content for individual cells.

Note that it is probably more common to define your models in the code, and one might consider it a layering violation to specify the content of a list store in a UI definition, data, not presentation, and common wisdom is to separate the two, as far as possible.

An example of a UI Definition fragment for a list store:

<object class="GtkListStore">
  <columns>
    <column type="gchararray"/>
    <column type="gchararray"/>
    <column type="gint"/>
  </columns>
  <data>
    <row>
      <col id="0">John</col>
      <col id="1">Doe</col>
      <col id="2">25</col>
    </row>
    <row>
      <col id="0">Johan</col>
      <col id="1">Dahlin</col>
      <col id="2">50</col>
    </row>
  </data>
</object>

Functions

append void append(gtk.tree_iter.TreeIter iter): Appends a new row to list_store. iter will be changed to point to this new row. The row will be empty after this function is called. To fill in values, you need to call gtk.list_store.ListStore.set or gtk.list_store.ListStore.setValue.
clear void clear(): Removes all rows from the list store.
insert void insert(gtk.tree_iter.TreeIter iter, int position): Creates a new row at position. iter will be changed to point to this new row. If position is -1 or is larger than the number of rows on the list, then the new row will be appended to the list. The row will be empty after this function is called. To fill in values, you need to call gtk.list_store.ListStore.set or gtk.list_store.ListStore.setValue.
insertAfter void insertAfter(gtk.tree_iter.TreeIter iter, gtk.tree_iter.TreeIter sibling): Inserts a new row after sibling. If sibling is null, then the row will be prepended to the beginning of the list. iter will be changed to point to this new row. The row will be empty after this function is called. To fill in values, you need to call gtk.list_store.ListStore.set or gtk.list_store.ListStore.setValue.
insertBefore void insertBefore(gtk.tree_iter.TreeIter iter, gtk.tree_iter.TreeIter sibling): Inserts a new row before sibling. If sibling is null, then the row will be appended to the end of the list. iter will be changed to point to this new row. The row will be empty after this function is called. To fill in values, you need to call gtk.list_store.ListStore.set or gtk.list_store.ListStore.setValue.
insertWithValues void insertWithValues(gtk.tree_iter.TreeIter iter, int position, int[] columns, gobject.value.Value[] values): A variant of gtk.list_store.ListStore.insertWithValues which takes the columns and values as two arrays, instead of varargs.
iterIsValid bool iterIsValid(gtk.tree_iter.TreeIter iter): Checks if the given iter is a valid iter for this gtk.list_store.ListStore.
moveAfter void moveAfter(gtk.tree_iter.TreeIter iter, gtk.tree_iter.TreeIter position): Moves iter in store to the position after position. Note that this function only works with unsorted stores. If position is null, iter will be moved to the start of the list.
moveBefore void moveBefore(gtk.tree_iter.TreeIter iter, gtk.tree_iter.TreeIter position): Moves iter in store to the position before position. Note that this function only works with unsorted stores. If position is null, iter will be moved to the end of the list.
prepend void prepend(gtk.tree_iter.TreeIter iter): Prepends a new row to list_store. iter will be changed to point to this new row. The row will be empty after this function is called. To fill in values, you need to call gtk.list_store.ListStore.set or gtk.list_store.ListStore.setValue.
remove bool remove(gtk.tree_iter.TreeIter iter): Removes the given row from the list store. After being removed, iter is set to be the next valid row, or invalidated if it pointed to the last row in list_store.
set void set(gtk.tree_iter.TreeIter iter, int[] columns, gobject.value.Value[] values): A variant of gtk.list_store.ListStore.setValist which takes the columns and values as two arrays, instead of varargs. This function is mainly intended for language-bindings and in case the number of columns to change is not known until run-time.
setColumnTypes void setColumnTypes(gobject.types.GType[] types): Sets the types of the columns of a list store.
setValue void setValue(gtk.tree_iter.TreeIter iter, int column, gobject.value.Value value): Sets the data in the cell specified by iter and column. The type of value must be convertible to the type of the column.
swap void swap(gtk.tree_iter.TreeIter a, gtk.tree_iter.TreeIter b): Swaps a and b in store. Note that this function only works with unsorted stores.

bindProperty gobject.binding.Binding bindProperty(string sourceProperty, gobject.object.ObjectG target, string targetProperty, gobject.types.BindingFlags flags): Creates a binding between source_property on source and target_property on target.
bindPropertyFull gobject.binding.Binding bindPropertyFull(string sourceProperty, gobject.object.ObjectG target, string targetProperty, gobject.types.BindingFlags flags, gobject.closure.Closure transformTo, gobject.closure.Closure transformFrom): Creates a binding between source_property on source and target_property on target, allowing you to set the transformation functions to be used by the binding.
forceFloating void forceFloating(): This function is intended for #GObject implementations to re-enforce a floating[floating-ref] object reference. Doing this is seldom required: all #GInitiallyUnowneds are created with a floating reference which usually just needs to be sunken by calling gobject.object.ObjectG.refSink.
freezeNotify void freezeNotify(): Increases the freeze count on object. If the freeze count is non-zero, the emission of "notify" signals on object is stopped. The signals are queued until the freeze count is decreased to zero. Duplicate notifications are squashed so that at most one #GObject::notify signal is emitted for each property modified while the object is frozen.
getData void* getData(string key): Gets a named field from the objects table of associations (see gobject.object.ObjectG.setData).
getProperty void getProperty(string propertyName, gobject.value.Value value): Gets a property of an object.
getQdata void* getQdata(glib.types.Quark quark): This function gets back user data pointers stored via gobject.object.ObjectG.setQdata.
getv void getv(string[] names, gobject.value.Value[] values): Gets n_properties properties for an object. Obtained properties will be set to values. All properties must be valid. Warnings will be emitted and undefined behaviour may result if invalid properties are passed in.

runDispose void runDispose(): Releases all references to other objects. This can be used to break reference cycles.
setData void setData(string key, void* data): Each object carries around a table of associations from strings to pointers. This function lets you set an association.
setProperty void setProperty(string propertyName, gobject.value.Value value): Sets a property on an object.
stealData void* stealData(string key): Remove a specified datum from the object's data associations, without invoking the association's destroy handler.
stealQdata void* stealQdata(glib.types.Quark quark): This function gets back user data pointers stored via gobject.object.ObjectG.setQdata and removes the data from object without invoking its destroy() function (if any was set). Usually, calling this function is only required to update user data pointers with a destroy notifier, for example:
thawNotify void thawNotify(): Reverts the effect of a previous call to gobject.object.ObjectG.freezeNotify. The freeze count is decreased on object and when it reaches zero, queued "notify" signals are emitted.
watchClosure void watchClosure(gobject.closure.Closure closure): This function essentially limits the life time of the closure to the life time of the object. That is, when the object is finalized, the closure is invalidated by calling gobject.closure.Closure.invalidate on it, in order to prevent invocations of the closure with a finalized (nonexisting) object. Also, gobject.object.ObjectG.ref_ and gobject.object.ObjectG.unref are added as marshal guards to the closure, to ensure that an extra reference count is held on object during invocation of the closure. Usually, this function will be called on closures that use this object as closure data.
connectNotify ulong connectNotify(string detail, T callback, Flag!"After" after): Connect to Notify signal.

getSortColumnId bool getSortColumnId(int sortColumnId, gtk.types.SortType order): Fills in sort_column_id and order with the current sort column and the order. It returns true unless the sort_column_id is GTK_TREE_SORTABLE_DEFAULT_SORT_COLUMN_ID or GTK_TREE_SORTABLE_UNSORTED_SORT_COLUMN_ID.
hasDefaultSortFunc bool hasDefaultSortFunc(): Returns true if the model has a default sort function. This is used primarily by GtkTreeViewColumns in order to determine if a model can go back to the default state, or not.
setDefaultSortFunc void setDefaultSortFunc(gtk.types.TreeIterCompareFunc sortFunc): Sets the default comparison function used when sorting to be sort_func. If the current sort column id of sortable is GTK_TREE_SORTABLE_DEFAULT_SORT_COLUMN_ID, then the model will sort using this function.
setSortColumnId void setSortColumnId(int sortColumnId, gtk.types.SortType order): Sets the current sort column to be sort_column_id. The sortable will resort itself to reflect this change, after emitting a GtkTreeSortable::sort-column-changed signal. sort_column_id may either be a regular column id, or one of the following special values:
setSortFunc void setSortFunc(int sortColumnId, gtk.types.TreeIterCompareFunc sortFunc): Sets the comparison function used when sorting to be sort_func. If the current sort column id of sortable is the same as sort_column_id, then the model will sort using this function.
sortColumnChanged void sortColumnChanged(): Emits a GtkTreeSortable::sort-column-changed signal on sortable.
connectSortColumnChanged ulong connectSortColumnChanged(T callback, Flag!"After" after): Connect to SortColumnChanged signal.
