incommingConnection not called by QTcpServer

[toufic.dbouk]

Hi all,
i have this Server but whenever i try to connect to it from the client side
the incommingConnection is not being executed
can anyone help me to know the reason and how to fix it ?
Thanks in advance.

Server:

#include "server.h"
#include "ui_server.h"
#include <myclient.h>

    QString rPath="whateverpath";
    UserModel= new QFileSystemModel(this);
    UserModel = new QFileSystemModel(this);
    UserModel->setRootPath(rPath);
    QModelIndex index= UserModel->index(rPath);

    UserFileModel = new QFileSystemModel(this);
    UserFileModel->setFilter(QDir::NoDotAndDotDot | QDir::Files | QDir::AllDirs);
    ui->UserFilesTableView->setModel(UserFileModel);
    ui->UserFilesTableView->resizeColumnsToContents();
    ui->UserFilesTableView->setColumnWidth(3,266);

Server is listening, but where is it accepting new connection?

You should have something like this

connect(mServer, SIGNAL(newConnection()), ....);
or
if(mServer->hasPendingConnections())
{
    QTcpSocket * clientSocket = mServer->nextPendingConnection ();
    clientSocket->readAll();
...
}

connect(mServer, SIGNAL(newConnection()), ....);
or
if(mServer->hasPendingConnections())
{
    QTcpSocket * clientSocket = mServer->nextPendingConnection ();
    clientSocket->readAll();
...
}
