ButtonGroup
===========

**Inherits:** :ref:`Resource<class_Resource>` **<** :ref:`RefCounted<class_RefCounted>` **<** :ref:`Object<class_Object>`

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

.. rst-class:: classref-introduction-group

Description
-----------

A group of :ref:`BaseButton<class_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 :ref:`CheckBox<class_CheckBox>`) may have a special appearance in this state.

Every member of a **ButtonGroup** should have :ref:`BaseButton.toggle_mode<class_BaseButton_property_toggle_mode>` set to ``true``.
