public class CheckBoxList
extends JList

An extended JList that contains CheckBoxes. If necessary a CheckBoxListItem wrapper is added around the displayed object in any of the Model methods, e.g., addElement. For methods returning objects the opposite takes place, the wrapper is removed and only the payload object is returned.
