+/**
+ * SECTION:gtkcelllayout
+ * @Short_Description: An interface for packing cells
+ * @Title: GtkCellLayout
+ *
+ * #GtkCellLayout is an interface to be implemented by all objects which
+ * want to provide a #GtkTreeViewColumn-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
+ * gtk_cell_layout_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 (#GtkCellView, #GtkIconView, #GtkComboBox, #GtkComboBoxEntry,
+ * #GtkEntryCompletion, #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.
+ *
+ *
+ * A UI definition fragment specifying attributes
+ *
+ *
+ *
+ *
+ * 0
+ *
+ * "
+ *
+ * ]]>
+ *
+ *
+ * Furthermore for implementations of GtkCellLayout that use a #GtkCellArea
+ * to lay out cells (all GtkCellLayouts in GTK+ use a GtkCellArea)
+ * 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.
+ *
+ * A UI definition fragment specifying cell properties
+ *
+ *
+ *
+ *
+ * True
+ * False
+ *
+ * "
