* @short A QButtonGroup with signal on new selection, plus Qt 2 compatibility.

|
*
|
||
|
|
* The ButtonGroup class provides an enhanced version of the QButtonGroup class.
|
||
|
|
*
|
||
|
|
* It emits an additional signal, buttonSet(int), whenever any of its buttons
|
||
|
|
* changes state, for whatever reason, including programmatic control. (The
|
||
|
|
* QButtonGroup class only emits signals when buttons are clicked on by the user.)
|
||
|
|
* The class also provides Qt 2 compatibility.
