Button control that provides selectable options when pressed.
.. rst-class:: classref-introduction-group
Description
-----------
OptionButton is a type button that provides a selectable list of items when pressed. The item selected becomes the "current" item and is displayed as the button text.
See also :ref:`BaseButton<class_BaseButton>` which contains common properties and methods associated with this node.
\ **Note:** The ID values used for items are limited to 32 bits, not full 64 bits of :ref:`int<class_int>`. This has a range of ``-2^32`` to ``2^32 - 1``, i.e. ``-2147483648`` to ``2147483647``.
