+ * @short A QCheckBox with focus widget and read-only options.
+ *
+ * The CheckBox class is a QCheckBox with the ability to transfer focus to another
+ * widget when checked, and with a read-only option.
+ *
+ * Another widget may be specified as the focus widget for the check box. Whenever
+ * the user clicks on the check box so as to set its state to checked, focus is
+ * automatically transferred to the focus widget.
+ *
+ * The widget may be set as read-only. This has the same effect as disabling it, except
+ * that its appearance is unchanged.
