public class JCStringCellRenderer

extends Object

implements JCLightCellRenderer

A classic String cell renderer based on the lightweight rendering model. This renderer handles all text rendering. Special features include multi-line detection and clip arrows.

This is the default String cell renderer in JClass.

This renderer does not handle HTML rendering. If you want HTML rendering for String data, use JCLabelCellRenderer. JCLabelCellRenderer is based on a JLabel, which handles HTML rendering.
