Class StyledTreeCellRenderer

All Implemented Interfaces:
ImageObserver, MenuContainer, Serializable, Accessible, SwingConstants, TreeCellRenderer

public class StyledTreeCellRenderer extends StyledLabel implements TreeCellRenderer
A tree cell renderer based on StyledLabel. To use it, you should make your cell renderer extending this one and override customizeStyledLabel(javax.swing.JTree, Object, boolean, boolean, boolean, int, boolean) method. If your overridden method, you can call setStyleRange() or setStyleRanges() based on the tree node value and row index.
