创建TCP Socket // client.cppClient::Client(QWidget*parent):QDialog(parent),hostCombo(newQComboBox),portLineEdit(newQLineEdit),statusLabel(newQLabel(tr("This examples requires that you run the\nMessage Server example as well."))),getMsgButton(newQPushButton(tr("Get Message"))),tcpSocket(ne...
connect(tcpSocket, QOverload<QAbstractSocket::SocketError>::of(&QAbstractSocket::error), ... } 按下Get Fortune按钮后会进入requestNewFortune这个槽函数: void Client::requestNewFortune() { getFortuneButton->setEnabled(false); tcpSocket->abort(); tcpSocket->connectToHost(hostCombo->currentText(),...
client.start() server.waitForNewConnection(1000) 等待1秒 ``` 以上代码首先定义了两个类,`TcpServer`和`TcpClient`,它们都继承自`QObject`。服务器端和客户端都有各自的信号和槽函数,用于处理TCP通信的不同阶段。 - `TcpServer`类中,我们定义了`readyRead`、`bytesWritten`和`disconnected`信号及相应的槽函数。

下面是一个简单的TCP客户端和服务器示例: TCP客户端示例: #include <QTcpSocket>#include <QMessageBox>class Client : public QObject {Q_OBJECTpublic:Client(const QHostAddress &host, quint16 port) {socket = new QTcpSocket(this);connect(socket, &QTcpSocket::connected, this, &Client::onConnected...
The onlyQTcpSocketsignals we need in this example areQTcpSocket::readyRead(), signifying that data has been received, andQTcpSocket::errorOccurred(), which we will use to catch any connection errors: ... connect(tcpSocket,&QIODevice::readyRead,this,&Client::readFortune); connect(tcpSocket...
In this blog, we will use the Simple MQTT Client Example to illustrate how to use MQTT for creating an application that communicates with an MQTT broker. Let's open the example project in QtCreator to see how this application runs. Let's go back to the directory we just downloaded using...
For TCP Socket in general, please visit my C++ Tutorials:Socket - Server and Client. Start We'll start with Qt Gui Application. Qt->Qt Gui Application: First, we need to add network module to our project file, LoopBackExample.pro: ...
与命令行版本的网络通信不同,图形化部分需要使用信号与槽函数进行绑定,所有的通信流程都是基于信号的,对于服务端而言我们需要导入QTcpServer、QtNetwork、QTcpSocket模块,并新增四个槽函数分别对应四个信号; 信号 槽函数 描述 connected() onClientConnected() 当tcpSocket 成功连接到远程主机时触发,执行 onClientConnec...
