    \brief Exclusive radio button that can be toggled on or off.

    \image qtquickcontrols2-radiobutton.gif

    RadioButton presents an option button that can be toggled on (checked) or
    off (unchecked). Radio buttons are typically used to select one option
    from a set of options.

    RadioButton inherits its API from \l AbstractButton. For instance,
    you can set \l {AbstractButton::text}{text} and react to
    \l {AbstractButton::clicked}{clicks} using the AbstractButton API.
    The state of the radio button can be set with the
    \l {AbstractButton::}{checked} property.

    Radio buttons are \l {AbstractButton::autoExclusive}{auto-exclusive}
    by default. Only one button can be checked at any time amongst radio
    buttons that belong to the same parent item; checking another button
    automatically unchecks the previously checked one. For radio buttons
    that do not share a common parent, ButtonGroup can be used to manage
    exclusivity.

    \l RadioDelegate is similar to RadioButton, except that it is typically
    used in views.

    \code
    ColumnLayout {
        RadioButton {
            checked: true
            text: qsTr("First")
        }
        RadioButton {
            text: qsTr("Second")
        }
        RadioButton {
            text: qsTr("Third")
        }
    }
