public class CellRenderer
extends GtkObject

A CellRenderer is an object used to render data in a TreeView widget. This is for all types of Table, Tree and list. Each renderer has one or more CellRendererAttribute. These attributes are for data to be rendered. This data is usually stored in a TreeModel object; the two current implementations of TreeModel being ListStore (for tables and lists) and TreeStore for trees.

The choice of data to be rendered is particular to the TreeView widget - any number of TreeView widgets may share the same data and choose to display only a selection of it. Data is displayed in a TreeView widget by attaching TreeViewColumns and packing any number of CellRenderers into each column. Links are then made between the renderers and the data in the model via the TreeViewColumn.addAttributeMapping(CellRenderer, CellRendererAttribute, DataColumn) method.

This class is a base class for the renderers, either home grown or any of the following standard renderers:

For a full overview of the tree and list objects, see the TreeView description.
