If you want to set the buttonStyleName style using an external .CSS file or <mx:Style /> block, you can use code similar to the following snippet:

<mx:Style>
    ButtonBar {
        buttonStyleName: myCustomButtonStyleName;
    }

    .myCustomButtonStyleName {
        cornerRadius: 16;
    }
</mx:Style>
