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));
