Server is not reading from client

[probine]

I have this very simple server and I would like it to be able to read any data from a client.

the .h file
**********************************

#ifndef CLIENTSERVER_H
#define CLIENTSERVER_H
 
#include <QMainWindow>
 
class QTextBrowser;
class QByteArray;
class QTcpSocket;
class QTcpServer;
 
 
class ClientServer : public QMainWindow
{
  Q_OBJECT
  private:
    QTextBrowser * textBrowser;
    QByteArray * byteArray;
    QTcpSocket * tcpSocket;
    QTcpServer * tcpServer;
 
  public:
    ClientServer();
 
  signals:  
 
  public slots:
    void readData();
 
};
 
# endif

#ifndef CLIENTSERVER_H
#define CLIENTSERVER_H

#include <QMainWindow>

class QTextBrowser;
class QByteArray;
class QTcpSocket;
class QTcpServer;


class ClientServer : public QMainWindow
{
  Q_OBJECT
  private:
    QTextBrowser * textBrowser;
    QByteArray * byteArray;
    QTcpSocket * tcpSocket;
    QTcpServer * tcpServer;
    
  public:
    ClientServer();
    
  signals:  
   
  public slots:
    void readData();
  
};

# endif

To copy to clipboard, switch view to plain text mode

the .cpp file
***************************************

#include <QTextBrowser>
#include <QByteArray>
#include <QTcpSocket>
#include <QTcpServer>
#include "clientserver.h"
 
ClientServer::ClientServer()
{
  textBrowser = new QTextBrowser(this);
  tcpServer = new QTcpServer();
  tcpSocket = new QTcpSocket();
  setCentralWidget(textBrowser);
  setFixedSize(500,500);
  show();
 
  if(tcpServer->listen(QHostAddress("localhost"), quint16(33333)))
    textBrowser->append("ClientServer is listening");
 
  tcpSocket->setSocketDescriptor(tcpServer->socketDescriptor());
  connect(tcpSocket, SIGNAL(readyRead()), this, SLOT(readData()));
 
}
 
void ClientServer::readData()
{
  textBrowser->append("Ready to read");
}

#include <QTextBrowser>
#include <QByteArray>
#include <QTcpSocket>
#include <QTcpServer>
#include "clientserver.h"

ClientServer::ClientServer()
{
  textBrowser = new QTextBrowser(this);
  tcpServer = new QTcpServer();
  tcpSocket = new QTcpSocket();
  setCentralWidget(textBrowser);
  setFixedSize(500,500);
  show();

  if(tcpServer->listen(QHostAddress("localhost"), quint16(33333)))
    textBrowser->append("ClientServer is listening");

  tcpSocket->setSocketDescriptor(tcpServer->socketDescriptor());
  connect(tcpSocket, SIGNAL(readyRead()), this, SLOT(readData()));
  
}

void ClientServer::readData()
{
  textBrowser->append("Ready to read");
}

I cannot even get to the readData() function.

Why?
How can I make it read from a client?

You should connect to signal QTcpServer::newConnection() and then use QTcpServer::nextPendingConnection() to get the socket whose signal QTcpSocket::readyRead() you are interested of. See the examples shipped with Qt or the Simple Chat example in our wiki.

I read now from the client (browser), but I cannot write to the browser. When I write to a telnet window, then the message is shown there, but the browser does not display the html message.

How can I solve it ?

[probine]

I don't want to make my code to complex...

I just want to know:

1. How can the server know that the browser has finished sending all its data ?

You don't know unless you provide some kind of "end-of-message" mark from the other side. Read this thread.
