如何在 ui->recordtextEdit->append(tr("错误")); 时停止//2 //3 //4的测试。 路过高手帮忙写下代码，菜鸟谢过
------解决方案--------------------
你的testCOM函数定义个返回值，判断真假的，头文件里不要void 这么写了，bool testCOM(...,...)
然后
- C/C++ code
bool MainWindow::testCOM(QString com, QString device) { if(recvbuff == sendbuff) { ui->textEdit->append(tr(" 正常")); return true； } else { ui->recordtextEdit->append(tr("错误")); return false； }}
