m_socketClient.moveToThread(&m_thread);connect(&m_thread,SIGNAL(started()),&m_socketClient,SLOT(slot_initSocket()));m_thread.start(); 经过Qt封装的socket我们使用起来非常方便,有数据到来可以读取后就会触发槽函数,如果使用继承QThread重新实现run()函数的方式,就会不可避免的遇到无法舒服使用信号和槽的...

connect(mTcpSocketThread,SIGNAL(signal_back(QString)),this,SLOT(slot_handle_data(QString))); 使用connect不成功有可能是如下原因 这里需要注意 信号函数和槽函数的参数列表应该一致 使用信号槽,需要在类中声明 Q_OBJECT宏 槽函数应该用“private slots:”来修饰 ...
在这个示例中,我们首先创建了一个QTcpSocket对象,并使用connectToHost方法连接到指定的主机和端口。然后,我们使用waitForConnected方法等待连接建立成功。一旦连接建立成功,我们使用write方法将数据写入连接,并通过flush方法确保数据发送到远程主机。接着,我们使用waitForReadyRead方法等待有数据可读,一旦有数据可读,我们使用readA...

在run()方法中new QTcpSocket;然后监听readyRead()信号connect(m_pTcpSocket,SIGNAL(readyRead()),this,SLOT(sloat_RecvData())); 问题是当需要给服务器发送一段命令时(使用m_pTcpSocket->write(byteArray);)程序会报出警告QSocketNotifier: socket notifiers cannot be enabled from another thread。
1、tcpSocketClient.connectToHost("127.0.0.1",8888); 连接到服务器端socket 2、发送数据到连接的socket QByteArray block; QDataStream out(&block, QIODevice::WriteOnly); out.setVersion(QDataStream::Qt_4_1); out<<quint16(0)<<QString("downrequest"); ...
