A group of buttons that doesn't allow more than one button to be pressed at a time.

描述

A group of BaseButton-derived buttons. The buttons in a ButtonGroup are treated like radio buttons: No more than one button can be pressed at a time. Some types of buttons (such as CheckBox) may have a special appearance in this state.
