    /// An object for rendering a single cell
    ///
    /// The [`CellRenderer`][crate::CellRenderer] is a base class of a set of objects used for
    /// rendering a cell to a [`cairo::Context`][crate::cairo::Context].  These objects are used primarily by
    /// the [`TreeView`][crate::TreeView] widget, though they aren’t tied to them in any
    /// specific way.  It is worth noting that [`CellRenderer`][crate::CellRenderer] is not a
    /// [`Widget`][crate::Widget] and cannot be treated as such.
    ///
    /// The primary use of a [`CellRenderer`][crate::CellRenderer] is for drawing a certain graphical
    /// elements on a [`cairo::Context`][crate::cairo::Context]. Typically, one cell renderer is used to
    /// draw many cells on the screen.  To this extent, it isn’t expected that a
    /// CellRenderer keep any permanent state around.  Instead, any state is set
    /// just prior to use using `GObject`s property system.  Then, the
    /// cell is measured using gtk_cell_renderer_get_preferred_size(). Finally, the cell
    /// is rendered in the correct location using gtk_cell_renderer_snapshot().
    ///
    /// There are a number of rules that must be followed when writing a new
    /// [`CellRenderer`][crate::CellRenderer].  First and foremost, it’s important that a certain set
    /// of properties will always yield a cell renderer of the same size,
    /// barring a style change. The [`CellRenderer`][crate::CellRenderer] also has a number of
    /// generic properties that are expected to be honored by all children.
    ///
    /// Beyond merely rendering a cell, cell renderers can optionally
    /// provide active user interface elements. A cell renderer can be
    /// “activatable” like [`CellRenderer`][crate::CellRenderer]Toggle,
    /// which toggles when it gets activated by a mouse click, or it can be
    /// “editable” like [`CellRenderer`][crate::CellRenderer]Text, which
    /// allows the user to edit the text using a widget implementing the
    /// [`CellEditable`][crate::CellEditable] interface, e.g. [`Entry`][crate::Entry].
    /// To make a cell renderer activatable or editable, you have to
    /// implement the [`CellRenderer`][crate::CellRenderer]Class.activate or
    /// [`CellRenderer`][crate::CellRenderer]Class.start_editing virtual functions, respectively.
    ///
    /// Many properties of [`CellRenderer`][crate::CellRenderer] and its subclasses have a
    /// corresponding “set” property, e.g. “cell-background-set” corresponds
    /// to “cell-background”. These “set” properties reflect whether a property
    /// has been set or not. You should not set them independently.
    ///
    /// This is an Abstract Base Class, you cannot instantiate it.
    ///
    /// ## Properties

    /// #### `cell-background`

    /// ## Signals
    ///
    ///
    /// #### `editing-canceled`
    ///  This signal gets emitted when the user cancels the process of editing a
    /// cell.  For example, an editable cell renderer could be written to cancel
    /// editing when the user presses Escape.
    ///
    /// See also: gtk_cell_renderer_stop_editing().
    ///
    ///
    ///
    ///
    /// #### `editing-started`
    ///  This signal gets emitted when a cell starts to be edited.
    /// The intended use of this signal is to do special setup
    /// on @editable, e.g. adding a [`EntryCompletion`][crate::EntryCompletion] or setting
    /// up additional columns in a [`ComboBox`][crate::ComboBox].
    ///
    /// See gtk_cell_editable_start_editing() for information on the lifecycle of
    /// the @editable and a way to do setup that doesn’t depend on the @renderer.
    ///
    /// Note that GTK doesn't guarantee that cell renderers will
    /// continue to use the same kind of widget for editing in future
    /// releases, therefore you should check the type of @editable
    /// before doing any specific setup, as in the following example:
    ///
    /// **⚠️ The following code is in c ⚠️**
    ///
    /// ```c
    /// static void
    /// text_editing_started (GtkCellRenderer *cell,
