org.jdesktop.swingx.renderer.TreeCellContext

public class TreeCellContext
extends CellContext<javax.swing.JTree>

Tree specific cellContext.

• PENDING: setters for icons?
• PENDING: use focus border as returned from list or table instead of rolling its own? The missing ui-border probably is a consequence of the border hacking as implemented in core default renderer. SwingX has a composite default which should use the "normal" border.
• PENDING: selection colors couple explicitly to SwingX - should we go JXTree as generic type?
