+ * A small box that displays a check or not, depending on it's

+ * has different semantics. <code>JCheckBox</code>es are usually
+ * used in multiple-choice scenarios, where a user can select 0..n
+ * of n different options. (This is in contrast to the general RadioButton
+ * semantics where the user can select exactly one of n options).
+ *
+ * Note however that this semantics is in no way enforced by the
+ * <code>JCheckBox</code>.
