[Interest] Quick Controls 2: custom control

I would be curious, in QtQuick.Control 1.x you could do the following:

import QtQuick 2.1
import QtQuick.Controls 1.1
import QtQuick.Controls.Private 1.0
import QtQuick.Controls.Styles 1.1

id: component
property int rotationbuttonWidth: 50
property bool pressed: false
property color borderHighlightColor: 'black'
property color pressColor: 'blue'
property color unpressColor: 'red'
// Style Can be a single Component into a singleton to create only once and
could hold the color for generic application color
style: Style
property Component panel:
readonly property var control: __control
implicitWidth: control.rotationbuttonWidth
implicitHeight: implicitWidth
radius: implicitWidth / 2
border.color: control.borderHighlightColor
border.width: 2
color: control.pressed ? control.pressColor : control.unpressColor
// add other control behavior here (MouseArea, current value, min, max...)

I also wonder what is the equivalent in QtQuick.Control 2.x ? Does it make
any sense at all, since the style is dropped ? Do we only have to build
them from scratch with Items and use some sort of style singleton to hold
the color, size and other application style parameters?

I would probably do a singleton with a loader that load my particular
settings that I could change on the fly.
