46 * A small box that displays a check or not, depending on it's
47 * <code>selected</code> state. This works very similar to
48 * {@link JToggleButton} and {@link JRadioButton}, but in UI design it
49 * has different semantics. <code>JCheckBox</code>es are usually
50 * used in multiple-choice scenarios, where a user can select 0..n
51 * of n different options. (This is in contrast to the general RadioButton
52 * semantics where the user can select exactly one of n options).
54 * Note however that this semantics is in no way enforced by the
55 * <code>JCheckBox</code>.
