How to use QSvgRenderer load .svg in scene QGraphicsScene ?

[Mikeeeeee]

Hi!
I save a QGraphicsScene to an svg file.
How to use QSvgRenderer load .svg in scene QGraphicsScene ?
If I do so, I get a white screen

    QString newPath = QFileDialog::getOpenFileName(this, trUtf8("Open SVG"),
                                                   path, tr("SVG files (*.svg)"));

    if (newPath.isEmpty())
            return;

        path = newPath;
        scene->clear();

        QSvgRenderer w;
        w.load(path);
        scene->setSceneRect(w.viewBoxF());

Hi,

What about using QGraphicsSvgItem ?

[Mikeeeeee]

I did so, but how to set my scene the myItem?

    QString newPath = QFileDialog::getOpenFileName(this, trUtf8("Open SVG"),
                                                   path, tr("SVG files (*.svg)"));

    if (newPath.isEmpty())
            return;

        path = newPath;
        scene->clear();

        //QSvgRenderer myRenderer;
        QSvgRenderer* myRenderer = new QSvgRenderer();
        myRenderer->load(path);
        //scene->setSceneRect(myRenderer->viewBoxF());
        QGraphicsSvgItem *myItem = new QGraphicsSvgItem();
        myItem->setSharedRenderer(myRenderer);

Please read documentation: https://doc.qt.io/qt-5/qgraphicsscene.html#addItem

Thanks. I did it, it worked.

    QString newPath = QFileDialog::getOpenFileName(this, trUtf8("Open SVG"),
                                                   path, tr("SVG files (*.svg)"));

    if (newPath.isEmpty())
            return;

        path = newPath;
        scene->clear();

        //QSvgRenderer myRenderer;
        QSvgRenderer* myRenderer = new QSvgRenderer();
        myRenderer->load(path);
        //scene->setSceneRect(myRenderer->viewBoxF());
        QGraphicsSvgItem *myItem = new QGraphicsSvgItem();
        myItem->setSharedRenderer(myRenderer);
        scene->addItem(myItem);
