Detailed Description

A QButtonGroup with signal on new selection, and button IDs.

The ButtonGroup class provides an enhanced version of the QButtonGroup class.

It emits an additional signal, buttonSet(QAbstractButton*), 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.)

It allows buttons to have associated ID numbers, which can be used to access the buttons.
