Qml in Qdockwidget

saitej

Hi

I am trying to display a qml application in a dockwidget. I tried using this code but it gives an error.

QDockWidget *dock = new QDockWidget("Rectangle", this);
 QQuickView *view = new QQuickView;
 view->setSource(QUrl::fromLocalFile("qrc:/qml_maps/RectViewer.qml"));
 dock->setWidget(view);

RectViewer.qml is a simple rectangle.

ApplicationWindow{
    id:_window
    visible: true
        Rectangle {
            width: 100
            height: 100
            color: "red"
            border.color: "black"
            border.width: 5
            radius: 10
        }  

}

I understand that setwidget requires a qwidget as the arg but how to send this qml-widget/appn in to dockwidget ?

QQuickView

Inherits: QQuickWindow
Inherits: QWindow
Inherits: QObject and QSurface

So dont think u can use it as QWidget.

However, i saw mention of
QWidget *QWidget::createWindowContainer(QWindow *window, QWidget *parent=0, Qt::WindowFlags flags=0)

which might work for you.

@saitej Use QQuickWidget instead of QWidget::createWindowContainer. It has several advantages over it.

Since it is an applicationwindow (as i want menubar), it gives this warning

QQuickWidget does not support using windows as a root item. If you wish to create your root window from QML, consider using QQmlApplicationEngine instead.

If I use QQmlApplicationEngine, I will not be able to send the engine.

@saitej Well the error that you encountered earlier by using:

QQuickView *view = new QQuickView;
view->setSource(QUrl::fromLocalFile("qrc:/qml_maps/RectViewer.qml"));

also is similar. You can't use QQuickView to load Window or ApplicationWindow which requires QQmlApplicationEngine . But as per your requirement you dont want to use
QQmlApplicationEngine. It seems you need to re-structure your requirements.

@p3c0

is there something similar to dockwidgets in qml? Can gridview be used for a similar purpose?

Is there something similar to QDockWidgets in QML?

@saitej, not to my knowledge. Per post/830426, stackoverflow.com/a/72717739's thread indicates that either one must utilise an external library, or reimplement it themselves.
