Resize image to fit in graphics view

Kinesis

I have code that display image with its name on listWidget . In that case the image won't fit in the graphics view.I tested some of resizing methods.But it doesn't work.Please take a look my code.

directory.setNameFilters({"*.png", "*.jpg"});

    for(const QFileInfo & finfo: directory.entryInfoList()){
        auto imageObject = new QImage();
        imageObject->load(finfo.absoluteFilePath());

        auto image = QPixmap::fromImage(*imageObject);

        QGraphicsScene *scene = new QGraphicsScene(this);

        scene->addPixmap(image);
        //scene->setSceneRect(image.rect());
        QGraphicsView *graphicsView = new QGraphicsView(scene);
        graphicsView->fitInView(scene->sceneRect(),Qt::KeepAspectRatio);

  auto    item = new QListWidgetItem("", ui->listWidget_main);
        auto    widget = new QWidget;
        auto    label = new QLabel(finfo.fileName());
        auto    vb = new QVBoxLayout;

        vb->addWidget(label);
        vb->addWidget(graphicsView);

        widget->setLayout(vb);
        widget->setMinimumSize(340,340);
        ui->listWidget_main->setItemWidget(item,widget);

}

Hi,

Why are you creating so many QGraphicsView objects and also why the QImage on the heap rather than on the stack ?

@SGaist
Sorry for late reply, this is just one part of my main code. In my main code I need to display videos , images and textedits on listWidget . I used QIcon to display image thumbnails . But if I use QIcon , I can display all but the images are behind the other widgets. It seems like the images are not arranged in listWidget.Thats why I use graphics view to list in listWidget.Thanks

Why are you using a QListWidget if it's only for showing more widgets ?

For this question , so if I don't use QListWidget , what should I use?
Suggestion please?
Here is the output what is going on .

As U see , the images don't fit.(this is using Graphics View)

In that case, QLabel is enough. Using QGraphicsView is a very expensive cost.

OK , I can use QLabel , but how can I resize image to fit in label??
Thanks for your suggestion.

@Kinesis

Just use QLabel::setScaledContents(true).
