显示不在Qt资源中的图片

Question

I am currently writing an application in Qt, which is basically a warehouse. An application reads CSV, enables user to process it and enables to show picture of each good. I tried displaying picture using QLabel and Pixmap, however nothing happens even though the file is in the same folder and the name provided is exactly as it should be. Is it the resources issue or my code fails somehow? Is there any possibility to display the image without adding it to resources in order to avoid adding many photos manually?

void ImageViewer::viewImage(QString imgName)
{
    QString pathWithName = imgName;
    pathWithName.append(".jpg");

    ui->label->setPixmap( QPixmap(pathWithName) );
    ui->label->show();
    update();
}

Sorry for any mistakes in post creation or code displaying here- it's my first post.

Edit: I am adding code from MainWindow (called CsvReader in my project) to how I'm invoking the method viewImage:

void CsvReader::on_imgView_clicked()
{
    ImageViewer* img = new ImageViewer(this);
    img->setModal(true);
    img->exec();
QModelIndex List selInd ui->tableView->selectionModel()->selectedIndexes();
QString id = model->item(selInd.first().row(), 0)->text();

img->viewImage(id);
}

Edit 2: Solved. Had to change path using QDir:

QDir* directory = new QDir("/home/kokos/Magazyn/photos");
QFileInfo checkFile(*directory, pathWithName);

Thanks in advance, Kokos

Answer 1

Confirm your file's location and existence first. Add this;

    QFileInfo checkFile(pathWithName);

    if (checkFile.exists() && checkFile.isFile()) {
        // your code
    }
