QTcpSocket - Cannot create children for a parent that is in a different thread

[Begginer]

Hello,
I am new to QT.
In my project I have QTcpServer with multithreading. I need to implement that when server recieve something from one client(client is GUI aplication), send it to all clients except the one who sent data. Problem occurs when I call socket->write(data) in function sendToAllClients() in server.cpp. I got following:
QObject:Cannot create children for the parent that is in different thread qt.

Could anyone please help me with this. I was searching about on google, but whatever I tried it doesn't work.
Thanks a lot.


My code is below:

mythread.cpp

MyThread::MyThread(qintptr ID, QObject *parent) :
    QThread(parent)
{
    this->socketDescriptor = ID;
    this->disconnectedSocket=-1;
}
 
void MyThread::run()
{
    socket = new QTcpSocket();
 
    if(!socket->setSocketDescriptor(this->socketDescriptor))
    {
        emit error(socket->error());
        return;
    }
 
    connect(socket, SIGNAL(readyRead()), this, SLOT(readyRead()), Qt::DirectConnection);
    connect(socket, SIGNAL(disconnected()), this, SLOT(disconnected()));
 
    exec();
}
 
void MyThread::readyRead()
{
    readyToRead=true;
 
    if(readyToRead==true)
        emit ReadyToReadAllSockets(); //ReadyToReadAllSockets() is signal I wrote to make connection between thread and server.
 
}

MyThread::MyThread(qintptr ID, QObject *parent) :
    QThread(parent)
{
    this->socketDescriptor = ID;
    this->disconnectedSocket=-1;
}

void MyThread::run()
{
    socket = new QTcpSocket();

    if(!socket->setSocketDescriptor(this->socketDescriptor))
    {
        emit error(socket->error());
        return;
    }

    connect(socket, SIGNAL(readyRead()), this, SLOT(readyRead()), Qt::DirectConnection);
    connect(socket, SIGNAL(disconnected()), this, SLOT(disconnected()));

    exec();
}

void MyThread::readyRead()
{
    readyToRead=true;

    if(readyToRead==true)
        emit ReadyToReadAllSockets(); //ReadyToReadAllSockets() is signal I wrote to make connection between thread and server.
    
}
