ARENAUI Button Panel

A button panel is a horizontal or vertical panel that contains buttons. Each button can have a text or image label. When a button is clicked, a message is sent over pubsub with the buttonName and buttonIndex.

Additional Python properties are available in the ArenauiButtonPanel API Reference.
