+/**
+ * GtkEntryCompletion:
+ *
+ * `GtkEntryCompletion` is an auxiliary object to provide completion functionality
+ * for `GtkEntry`.
+ *
+ * It implements the [iface@Gtk.CellLayout] interface, to allow the user
+ * to add extra cells to the `GtkTreeView` with completion matches.
+ *
+ * “Completion functionality” means that when the user modifies the text
+ * in the entry, `GtkEntryCompletion` checks which rows in the model match
+ * the current content of the entry, and displays a list of matches.
+ * By default, the matching is done by comparing the entry text
+ * case-insensitively against the text column of the model (see
+ * [method@Gtk.EntryCompletion.set_text_column]), but this can be overridden
+ * with a custom match function (see [method@Gtk.EntryCompletion.set_match_func]).
+ *
+ * When the user selects a completion, the content of the entry is
+ * updated. By default, the content of the entry is replaced by the
+ * text column of the model, but this can be overridden by connecting
+ * to the [signal@Gtk.EntryCompletion::match-selected] signal and updating the
+ * entry in the signal handler. Note that you should return %TRUE from
+ * the signal handler to suppress the default behaviour.
+ *
+ * To add completion functionality to an entry, use
+ * [method@Gtk.Entry.set_completion].
+ *
+ * `GtkEntryCompletion` uses a [class@Gtk.TreeModelFilter] model to
+ * represent the subset of the entire model that is currently matching.
+ * While the `GtkEntryCompletion` signals
+ * [signal@Gtk.EntryCompletion::match-selected] and
+ * [signal@Gtk.EntryCompletion::cursor-on-match] take the original model
+ * and an iter pointing to that model as arguments, other callbacks and
+ * signals (such as `GtkCellLayoutDataFunc` or
+ * [signal@Gtk.CellArea::apply-attributes)]
+ * will generally take the filter model as argument. As long as you are
+ * only calling [method@Gtk.TreeModel.get], this will make no difference to
+ * you. If for some reason, you need the original model, use
+ * [method@Gtk.TreeModelFilter.get_model]. Don’t forget to use
+ * [method@Gtk.TreeModelFilter.convert_iter_to_child_iter] to obtain a
+ * matching iter.
+ *
