希望在主線程中創(chuàng)建多個子線程，在各個子線程中進(jìn)行串口數(shù)據(jù)收發(fā)及解析，發(fā)現(xiàn)在子線程中創(chuàng)建串口對象，總是不響應(yīng)串口消息，readData()中打斷點怎么都進(jìn)不去，跪求大俠指點！ 代碼如下： 主線程中創(chuàng)建子線程： <pre class='brush: cpp'>QMyThread *MyThread = new QMyThread; MyThread->start();</pre> 子線程中創(chuàng)建串口對象： <pre class='brush: cpp'>void QMyThread::run() { m_MyConn = new MyConnect(this,&(pRtuObj->m_strCommType),&(pRtuObj->m_sListSerialPara),&(pRtuObj->m_sListNetPara)); m_MyConn->openCommu(); m_MyConn->moveToThread(this); } 打開串口： //通信連接 void MyConnect::openCommu() { if(m_Serial != NULL) { delete m_Serial; m_Serial = NULL; } m_Serial = new QSerialPort; connect(m_Serial, SIGNAL(readyRead()), this, SLOT(readData())); m_Serial->setPortName(m_CommSettings.name); m_Serial->setBaudRate(m_CommSettings.baudRate); m_Serial->setDataBits(m_CommSettings.dataBits); m_Serial->setParity(m_CommSettings.parity); m_Serial->setStopBits(m_CommSettings.stopBits); if (m_Serial>open(QIODevice::ReadWrite)) { SendEvent(tr("Connected to %1").arg(m_CommSettings.m_sListSerialPara.join(","))); m_chCommuStatus = 1; } else { SendEvent(tr("Open Serial Error, %1").arg(m_CommSettings.m_sListSerialPara.join(","))); m_chCommuStatus = 0; } } 串口讀數(shù)據(jù): //串口讀數(shù)據(jù) void MyConnect::readData() { QByteArray buffer = m_Serial->readAll(); displayRxTxData(buffer); }</pre>
