I have this code:

import QtQuick 2.0
import QtQuick.Window 2.12
import QtQuick.Controls 2.14

Window {
    id: window
    visible: true
    width: 640
    height: 480
    title: qsTr("Window")

    SpinBox{
        up.hovered :true
    }
}

But when I run it, I get this error:

".hovered" is not available due to component versioning.

The error is the same this properties for up and down group:

• implicitIndicatorHeight
• implicitIndicatorWidth
• hovered

In  the documentation SpinBox , they say "The up.hovered property was introduced in QtQuick.Controls 2.1, and the up.implicitIndicatorWidth and up.implicitIndicatorHeight properties were introduced in QtQuick.Controls 2.5"
