    /// want to provide a [`TreeViewColumn`][crate::TreeViewColumn] like API for packing cells,
    /// setting attributes and data funcs.
    ///
    /// One of the notable features provided by implementations of
    /// GtkCellLayout are attributes. Attributes let you set the properties
    /// in flexible ways. They can just be set to constant values like regular
    /// properties. But they can also be mapped to a column of the underlying
    /// tree model with `gtk_cell_layout_set_attributes()`, which means that the value
    /// of the attribute can change from cell to cell as they are rendered by
    /// the cell renderer. Finally, it is possible to specify a function with
    /// [`CellLayoutExt::set_cell_data_func()`][crate::prelude::CellLayoutExt::set_cell_data_func()] that is called to determine the
    /// value of the attribute for each cell that is rendered.
    ///
    /// # GtkCellLayouts as GtkBuildable
    ///
    /// Implementations of GtkCellLayout which also implement the GtkBuildable
    /// interface ([`CellView`][crate::CellView], [`IconView`][crate::IconView], [`ComboBox`][crate::ComboBox],
    /// [`EntryCompletion`][crate::EntryCompletion], [`TreeViewColumn`][crate::TreeViewColumn]) accept GtkCellRenderer objects
    /// as ``<child>`` elements in UI definitions. They support a custom ``<attributes>``
    /// element for their children, which can contain multiple ``<attribute>``
    /// elements. Each ``<attribute>`` element has a name attribute which specifies
    /// a property of the cell renderer; the content of the element is the
    /// attribute value.
    ///
    /// This is an example of a UI definition fragment specifying attributes:
    ///
    ///
    ///
    /// **⚠️ The following code is in xml ⚠️**
    ///
    /// ```xml
    /// <object class="GtkCellView">
    ///   <child>
    ///     <object class="GtkCellRendererText"/>
    ///     <attributes>
    ///       <attribute name="text">0</attribute>
    ///     </attributes>
    ///   </child>
    /// </object>
    /// ```
    ///
    /// Furthermore for implementations of GtkCellLayout that use a [`CellArea`][crate::CellArea]
    /// to lay out cells (all GtkCellLayouts in GTK+ use a GtkCellArea)
    /// [cell properties][cell-properties] can also be defined in the format by
    /// specifying the custom ``<cell-packing>`` attribute which can contain multiple
    /// ``<property>`` elements defined in the normal way.
    ///

    /// # Subclassing GtkCellLayout implementations
    ///
    /// When subclassing a widget that implements [`CellLayout`][crate::CellLayout] like
    /// [`IconView`][crate::IconView] or [`ComboBox`][crate::ComboBox], there are some considerations related
    /// to the fact that these widgets internally use a [`CellArea`][crate::CellArea].
    /// The cell area is exposed as a construct-only property by these

    ///
    /// ```C
    /// combo = g_object_new (GTK_TYPE_COMBO_BOX, "cell-area", my_cell_area, NULL);
    /// ```
    ///
    /// to use a custom cell area with a combo box. But construct properties
    /// are only initialized after instance `init()`
    /// functions have run, which means that using functions which rely on
    /// the existence of the cell area in your subclass’ `init()` function will
    /// cause the default cell area to be instantiated. In this case, a provided
    /// construct property value will be ignored (with a warning, to alert
    /// you to the problem).
    ///
    ///
    ///
    /// **⚠️ The following code is in C ⚠️**
    ///
    /// ```C
    /// static void
    /// my_combo_box_init (MyComboBox *b)
    /// {
    ///   GtkCellRenderer *cell;
    ///
    ///   cell = gtk_cell_renderer_pixbuf_new ();
