QML anchors to ApplicationWindow via id not work

Question

I test a simple QML(Qt sdk version 5.3.2) program like this

import QtQuick 2.3
import QtQuick.Controls 1.2

ApplicationWindow {
    visible: true
    width:          


        

Answer 1

This looks like a bug, but it can be by design according following docs:

For performance reasons, you can only anchor an item to its siblings and direct parent

It's not really clear how we can specify direct parent when anchoring. QML translator may only accept parent to reference parent qml item.
