# QtObject QML Type

A basic QML type More...

Import Statement: | import QtQml 2.2

- List of all members, including inherited members

## Properties

- objectName : string

## 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.

## Property Documentation

objectName : string

This property holds the QObject::objectName for this specific object instance.

This allows a C++ application to locate an item within a QML component using the QObject::findChild() method. For example, the following C++ application locates the child Rectangle item and dynamically changes its `color` value:

    // 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));
