[Interest] Quick Controls 2: custom control

[Alexander Dyagilev]

Hello,

I know about a possibility to customize existing controls.
(http://doc.qt.io/qt-5/qtquickcontrols2-customize.html)

But what if I would like to create completely new one? Including ability 
to draw it by myself.

Is it possible with Quick Controls2?

If yes, please give me a link to the docs from which I could start.

I failed to find one....
