Set property of qml object using c++

Question

I have tried with

 widget->setProperty("text1Text", QVariant("After..."));

in my C++, and

 Button { property alias text1Text: text1.text Text { id: text1 text: "Initial" } }

in qml. widget is a QQuickWidget object. What am I doing wrong?

See Interacting with QML Objects from C++.

If you are using QQmlEngine:

// Using QQmlComponent QQmlApplicationEngine engine; ... QObject * root = engine.rootObjects().first();

If you are using QQuickView:

QQuickView view; ... QObject * root = view.rootObject();

Getting text1:

// Update Qml file Text { id: text1 text: "Initial" objectName: id } // Find text1 in c++ QObject * o1 = root->findChild<QObject *>(QStringLiteral("text1")); QQuickItem *text1 = qobject_cast<QQuickItem*>(o1); // Set property text1->setProperty("text", QVariant());

It looks like engine does not have a rootObjects() member, only rootContext()
Yes, rootObjects() appeared in QQmlAllicationEngine. I fixed samples.
