    Hi, I'm trying to view an image on QGraphicsView from resources using QPixMap, but I don't know how to load it from it.
    I found some code on the internet, but it's using QFileDialog, not resources.
    Heres the code:

    void MainWindow::on_pushButton_clicked()
    {
        QString filename = QFileDialog::getOpenFileName(this,
                                                            tr("Load Image"),
                                                            mResourceDir,
                                                            tr("Images (*.png *.jpg)"));
    
            if (filename.isEmpty())  {
                return;
            }
    
            QPixmap p(filename);
            if (! ui->graphicsView->scene()) {
                qDebug() << "No Scene!";
    
                QGraphicsScene *scene = new QGraphicsScene(this);
                ui->graphicsView->setScene(scene);
            }
            ui->graphicsView->scene()->addPixmap(p);
    }

      Hi,

      Use the qrc path:

      QPixmap pixmap(":/myfile.png");
