    /// [`EntryCompletion`][crate::EntryCompletion] is an auxiliary object to be used in conjunction with
    /// [`Entry`][crate::Entry] to provide the completion functionality. It implements the
    /// [`CellLayout`][crate::CellLayout] interface, to allow the user to add extra cells to the
    /// [`TreeView`][crate::TreeView] with completion matches.
    ///
    /// “Completion functionality” means that when the user modifies the text
    /// in the entry, [`EntryCompletion`][crate::EntryCompletion] 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
    /// [`EntryCompletionExt::set_text_column()`][crate::prelude::EntryCompletionExt::set_text_column()]), but this can be overridden
    /// with a custom match function (see [`EntryCompletionExt::set_match_func()`][crate::prelude::EntryCompletionExt::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::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 [`EntryExt::set_completion()`][crate::prelude::EntryExt::set_completion()].
    ///
    /// In addition to regular completion matches, which will be inserted into the
    /// entry when they are selected, [`EntryCompletion`][crate::EntryCompletion] also allows to display
    /// “actions” in the popup window. Their appearance is similar to menuitems,
    /// to differentiate them clearly from completion strings. When an action is
    /// selected, the `signal::EntryCompletion::action-activated` signal is emitted.
    ///
    /// GtkEntryCompletion uses a [`TreeModelFilter`][crate::TreeModelFilter] model to represent the
    /// subset of the entire model that is currently matching. While the
    /// GtkEntryCompletion signals `signal::EntryCompletion::match-selected` and
    /// `signal::EntryCompletion::cursor-on-match` take the original model and an
    /// iter pointing to that model as arguments, other callbacks and signals
    /// (such as `GtkCellLayoutDataFuncs` or `signal::CellArea::apply-attributes`)
    /// will generally take the filter model as argument. As long as you are
    /// only calling `gtk_tree_model_get()`, this will make no difference to
    /// you. If for some reason, you need the original model, use
    /// [`TreeModelFilterExt::model()`][crate::prelude::TreeModelFilterExt::model()]. Don’t forget to use
