Class AbstractRenderer

java.lang.Object

org.jdesktop.swingx.renderer.AbstractRenderer

All Implemented Interfaces:

Serializable, UIDependent, StringValue, RolloverRenderer

Direct Known Subclasses:

DefaultListRenderer, DefaultTableRenderer, DefaultTreeRenderer

public abstract class AbstractRenderer
extends Object
implements RolloverRenderer, StringValue, Serializable, UIDependent

Convenience common ancestor for SwingX renderers. Concrete subclasses should

• provide a bunch of convenience constructors as appropriate for the type of collection component
• create a reasonable default ComponentProvider if none is given
• implement the getXXCellRenderer by delegating to the ComponentProvider
