Detailed Description

The QtObject type is a non-visual element which contains only the objectName property.

It can be useful to create a QtObject if you need an extremely lightweight type to enclose a set of custom properties:

import QtQuick 2.0

Item {
    QtObject {
        id: attributes
        property string name
        property int size
        property variant attributes
    }

    Text { text: attributes.name }
}

It can also be useful for C++ integration, as it is just a plain QObject. See the QObject documentation for further details.

// MyRect.qml

import QtQuick 2.0

Item {
    width: 200; height: 200

    Rectangle {
        anchors.fill: parent
        color: "red"
        objectName: "myRect"
    }
}

// main.cpp

QQuickView view;
view.setSource(QUrl::fromLocalFile("MyRect.qml"));
view.show();

QQuickItem *item = view.rootObject()->findChild<QQuickItem*>("myRect");
if (item)
    item->setProperty("color", QColor(Qt::yellow));
