* The CheckBox class is a TQCheckBox 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.
