# class `RadioButton(Control)`

A RadioButton is similar to a CheckBox, except that RadioButtons are typically arranged in mutually-exclusive groups, so that only one member of a group is on at a time. The appearance of a RadioButton may differ from that of a CheckBox, depending on platform conventions.

The RadioGroup class is used to coordinate the behaviour of a group of RadioButtons. Unlike CheckBoxes, RadioButtons do not have individual on or action properties; the function of these is performed by the RadioGroup to which the radio buttons belong.

## Properties

> `title`
>   Title string to display beside the radio button.
> `group`
>   The RadioGroup instance to which this button belongs.
> `value`
>   Value associated with this RadioButton. If attached to a RadioGroup, when the button is selected the value of the group will be set to this value.
