Qt - Cannot put an image in a table

Question

Why with the following code I just get an empty table widget?

QString imgPath = \"C:\\\\path\\\\to\\\\image.jpg\";
QImage *img = new QImage(imgPath);

QTable

You are doing all almost right, but try to control your img, for example, like this:

QString imgPath = "C:\\path\\to\\image.jpg";
QImage *img = new QImage();
bool loaded = img->load(imgPath);
if (loaded)
{

    QTableWidget     *thumbnailsWidget = new QTableWidget;
    QTableWidgetItem *thumbnail = new QTableWidgetItem;
    thumbnail->setData(Qt::DecorationRole, QPixmap::fromImage(*img));

    thumbnailsWidget->setColumnCount(5);
    thumbnailsWidget->setRowCount(3);
    thumbnailsWidget->setItem(0, 0, thumbnail);

    w.setCentralWidget(thumbnailsWidget);
} else {
    qDebug()<<"Image "<

Hope, it helps you! Good luck!
