QIODevice 设置

设备的打开方式：OpenMode

enum QIODevice::OpenModeFlag
flags QIODevice::OpenMode

代码简单如下所示：

 void AdControlWidget::insertRepairData()
 {
     QString  pathstr  = "/app/config/repairdata.txt";
     QFile data(pathstr);
     if (data.open(QFile::WriteOnly |QIODevice::WriteOnly)) {   //
         QTextStream out(&data);
         for(int i =0;i<8;i++)
         {
             out << forms[i]->getrepairtime();
             out <<",";
             out << forms[i]->getrepairreason();
             out << "\n";
         }
     }
     data.close();
 }
