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(); }
