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