/**
|
|
* @short A TQRadioButton with focus widget and read-only options.
|
|
*
|
|
* The RadioButton class is a TQRadioButton 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 radio button. Whenever
|
|
* the user clicks on the radio button 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.
