A CellRenderer is an object used to reder 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.
