Qt中读取所选文件夹下所有图片至vector内

    vector<QImage> vecImg;
    QString folderName = QFileDialog::getExistingDirectory(this, tr("Open Folder"), QString());
    if (!folderName.isEmpty()) {
        QDir dir(folderName);
        vecImg.clear();
        foreach(QFileInfo imageFileInfo, dir.entryInfoList(QStringList() << "*.jpg" << "*.png" << "*.bmp", QDir::Files, QDir::NoSort))
        {
            QString  imgName = imageFileInfo.absoluteFilePath();
            QImage img(imgName);
            vecImg.push_back(img);
        }
    }
