All Implemented Interfaces:

CheckboxTreeCellRenderer, ImageObserver, MenuContainer, Serializable, Accessible, TreeCellRenderer

public class DefaultCheckboxTreeCellRenderer
extends JPanel
implements CheckboxTreeCellRenderer

A renderer for the CheckboxTree. This implementation decorates a DefaultTreeCellRenderer (i.e. a JLabel) with a checkbox, by adding a QuadristateCheckbox to the former onto a JPanel. Both can be overridden by subclasses. Note that double-clicking the label/icon of this renderer does not toggle the checkbox.
