QT中搜索文件列表

1.使用boost库

  std::string query_path = "C:/Users/zx/Desktop/robots/config";

  std::vector<std::string> file_name;
  boost::filesystem::directory_iterator end;
  for ( boost::filesystem::directory_iterator iter( query_path ); iter != end; iter++ )
  {
    if ( boost::filesystem::is_regular_file( *iter ) )
    {
      std::string log_file = iter->path().filename().string().data();
      file_name.push_back(  log_file );
    }
  }

2.使用qt自身的库

  const QString& mapPath = "C:/Users/zx/Desktop/robots/config";
  QDir localDir( mapPath );
  localDir.setNameFilters( QStringList() << "*.yaml" << "*.json" );

  for ( QFileInfo fi : localDir.entryInfoList() )
  {
    qDebug()<< fi.absoluteFilePath();
  }
