All Implemented Interfaces:

IColumnHeaderRenderer, java.awt.image.ImageObserver, java.awt.MenuContainer, java.io.Serializable, javax.accessibility.Accessible, javax.swing.SwingConstants

public class DefaultColumnHeaderRenderer
extends javax.swing.JLabel
implements IColumnHeaderRenderer

The default colum header renderer displays the column's name. The renderer looks up a header value via TreeTableColumn.getHeaderValue() and then invokes Object.toString() on it.
