/// List views use widgets for displaying their
/// contents
/// 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

/// ## 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,
/// GtkCellEditable *editable,
/// const char *path,
/// gpointer data)
/// {
/// if (GTK_IS_ENTRY (editable))
/// {
/// GtkEntry *entry = GTK_ENTRY (editable);
///
/// // ... create a GtkEntryCompletion
///
/// gtk_entry_set_completion (entry, completion);
/// }
/// }
/// ```
///
///
///
/// # Implements
///
