\section{Implementations}{GtkCellLayout is implemented by
\code{\link{GtkCellView}}, \code{\link{GtkComboBox}}, \code{\link{GtkComboBoxEntry}}, \code{\link{GtkEntryCompletion}}, \code{\link{GtkIconView}} and \code{\link{GtkTreeViewColumn}}.}
\section{Detailed Description}{\code{\link{GtkCellLayout}} is an interface to be implemented by all objects which
want to provide a \verb{GtkTreeViewColumn-like} API for packing cells, setting
attributes and data funcs.
One of the notable features provided by implementations of GtkCellLayout
are \emph{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 \code{\link{gtkCellLayoutSetAttributes}}, 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
\code{\link{gtkCellLayoutSetCellDataFunc}} that is called to determine the value
of the attribute for each cell that is rendered.}
\section{GtkCellLayouts as GtkBuildable}{Implementations of GtkCellLayout which also implement the GtkBuildable
interface (\code{\link{GtkCellView}}, \code{\link{GtkIconView}}, \code{\link{GtkComboBox}}, \code{\link{GtkComboBoxEntry}},
\code{\link{GtkEntryCompletion}}, \code{\link{GtkTreeViewColumn}}) 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.
\emph{A UI definition fragment specifying attributes}\preformatted{<object class="GtkCellView">
<child>
<object class="GtkCellRendererText"/>
<attributes>
<attribute name="text">0</attribute>
</attributes>
</child>"
</object>
