std::vector<QString> GetFileList(QString dir)
{
std::vector<QString> filePath;
QDir dirPath(dir);
QList<QFileInfo> file(dirPath.entryInfoList());
QString name = "";

for (auto it = file.begin(); it != file.end(); it++)
{
name = dir + "/" + it->fileName();
if (*it->isFile())
{
filePath.push_back(name);
}
}
return filePath;
}
