public class JBDefaultTableCellRenderer
extends HyperLinkLabel
implements javax.swing.table.TableCellRenderer, java.io.Serializable

Based upon code from JDK class java.swing.table.DefaultTableCellRenderer. The standard class for rendering (displaying) individual cells in a JTable.

Implementation Note: This class inherits from JLabel, a standard component class. However JTable employs a unique mechanism for rendering its cells and therefore requires some slightly modified behavior from its cell renderer. The table class defines a single cell renderer and uses it as a as a rubber-stamp for rendering all cells in the table; it renders the first cell, changes the contents of that cell renderer, shifts the origin to the new location, re-draws it, and so on. The standard JLabel component was not designed to be used this way and we want to avoid triggering a revalidate each time the cell is drawn. This would greatly decrease performance because the revalidate message would be passed up the hierarchy of the container to determine whether any other components would be affected. So this class overrides the validate, revalidate, repaint, and firePropertyChange methods to be no-ops. If you write your own renderer, please keep this performance consideration in mind.

Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeansTM has been added to the java.beans package. Please see XMLEncoder.
