How to nest QWidget in QML?

abollo2

I now need to nest a player window in QML, but the player window is developed using QWidget.

I found a way, but I can't handle the QML level problem, the player window will always be blocked on the QML interface.

QQmlApplicationEngine engine;
const QUrl url(QStringLiteral("qrc:/main.qml"));
engine.load(url);

QObject *qmlObj = engine.rootObjects().first();
QWindow *qmlWindow = qobject_cast<QWindow *>(qmlObj);

QWidget *fm = new QWidget();
fm->winId();
fm->setAttribute(Qt::WA_NativeWindow);
fm->windowHandle()->setParent(qmlWindow);
fm->move(40, 40);
fm->show();

How can I nest QWidget into QML, just like QML Item.

please help me.

This is not possible. No QWidgets inside the qml.

Hi
This might be interesting
https://www.kdab.com/declarative-widgets/
But else @dheerendra is right and its really not natively supported.

We allways need QWidget in QML, does anyone else has some ideas?
Thanks for help.

@kate-he You can always go the other way, and make your application a QWidget application and load Qml stuff via QQuickView and/or QQuickWidgets

@J-Hilk Thanks for ur ideas and We've thought about that before.
If we do what you say, that means we need to refactor our exsiting project.
That would be a huge job, which can't be done in a very short time.

Are there any paid services in QT official, that can be customized for us to make QWidget embedded in QML possible？

@kate-he Hi,

As @mrjj already pointed, KDAB's Declarative Widgets are the way to go.

They are one of the biggest Qt consulting company so if you need support for that part, you should contact them.
