Class SmartRenderer

java.lang.Object

net.mtu.eggplant.util.gui.SmartRenderer

All Implemented Interfaces:

javax.swing.ListCellRenderer<java.lang.Object>, javax.swing.table.TableCellRenderer, javax.swing.tree.TreeCellRenderer

public class SmartRenderer
extends java.lang.Object
implements javax.swing.ListCellRenderer<java.lang.Object>, javax.swing.table.TableCellRenderer, javax.swing.tree.TreeCellRenderer

Class that knows how to render lots of things. If you want to create a renderer, just subclass this SmartRenderer and override the getStringValue() method. For any object that is not a known type toString is used. Null values are always displayed as "NULL". This class counts on the fact that the default renderers for list, trable and tree all return a subclass of JLabel. If that ever changes, this class breaks.
