Class AbstractCellRenderer

java.lang.Object
  dsto.dfc.swing.controls.AbstractCellRenderer

All Implemented Interfaces:

CellRenderer, ListCellRenderer, TableCellRenderer, TreeCellRenderer

Direct Known Subclasses:

ColorCellRenderer, FontCellRenderer, IconicCellRenderer

public abstract class AbstractCellRenderer
extends Object
implements CellRenderer

Base for classes that want to implement a cell renderer that can be used interchangably for lists, tables and trees: classes implement one method (getRendererComponent ()) to provide a renderer for all 3 interfaces. Provides support for setting colours, borders etc based on behaviour of default renderers.
