# QtObject QML Type

A basic QML type. More...

Import Statement: | `import QtQml`
In C++: | QObject

- 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

     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));
