    /// [`SignalListItemFactory`][crate::SignalListItemFactory] is a [`ListItemFactory`][crate::ListItemFactory] that emits signals
    /// to to manage listitems.
    ///
    /// Signals are emitted for every listitem in the same order:
    ///
    ///  1. `signal::SignalListItemFactory::setup` is emitted to set up permanent
    ///  things on the listitem. This usually means constructing the widgets used in
    ///  the row and adding them to the listitem.
    ///
    ///  2. `signal::SignalListItemFactory::bind` is emitted to bind the item passed
    ///  via `property::ListItem::item` to the widgets that have been created in
    ///  step 1 or to add item-specific widgets. Signals are connected to listen to
    ///  changes - both to changes in the item to update the widgets or to changes
    ///  in the widgets to update the item. After this signal has been called, the
    ///  listitem may be shown in a list widget.
    ///
    ///  3. `signal::SignalListItemFactory::unbind` is emitted to undo everything
    ///  done in step 2. Usually this means disconnecting signal handlers. Once this
    ///  signal has been called, the listitem will no longer be used in a list
    ///  widget.
    ///
    ///  4. `signal::SignalListItemFactory::bind` and
    ///  `signal::SignalListItemFactory::unbind` may be emitted multiple times
    ///  again to bind the listitem for use with new items. By reusing listitems,
    ///  potentially costly setup can be avoided. However, it means code needs to
    ///  make sure to properly clean up the listitem in step 3 so that no information
    ///  from the previous use leaks into the next use.
    ///
    /// 5. `signal::SignalListItemFactory::teardown` is emitted to allow undoing
    /// the effects of `signal::SignalListItemFactory::setup`. After this signal
    /// was emitted on a listitem, the listitem will be destroyed and not be used again.
    ///
    /// Note that during the signal emissions, changing properties on the
    /// [`ListItem`][crate::ListItem]s passed will not trigger notify signals as the listitem's
    /// notifications are frozen. See `g_object_freeze_notify()` for details.
    ///
    /// For tracking changes in other properties in the [`ListItem`][crate::ListItem], the
    /// ::notify signal is recommended. The signal can be connected in the
    /// `signal::SignalListItemFactory::setup` signal and removed again during
    /// `signal::SignalListItemFactory::teardown`.
