QUdpSocket running in QThread - change port

[sanji]

Hi everyone!
A simple question, but cannot find any solution.

I have a class:

class Test: public QThread
{
    Q_OBJECT
public:
    Test();
    int port;                 //An UDP port to bind to
    QUdpSocket *so;
    void run() override;      // creates, assigns an QUdpSocket object to the so variable, and binds it to some initial port.
 
public slots:
    void reconnect();         // Should bind socket to some other port, than the one bound while initializing.
    void receive();           // Called to receive datagram. Works fine.
};

class Test: public QThread
{
    Q_OBJECT
public:
    Test();
    int port;                 //An UDP port to bind to
    QUdpSocket *so;
    void run() override;      // creates, assigns an QUdpSocket object to the so variable, and binds it to some initial port.

public slots:
    void reconnect();         // Should bind socket to some other port, than the one bound while initializing.
    void receive();           // Called to receive datagram. Works fine.
};

To copy to clipboard, switch view to plain text mode 

The run() function looks like (simplyfied):

void Test::run()
{
    so = new QUdpSocket();
    so->bind(port);
    this->exec();
    so->deleteLater();
}

void Test::run()
{
    so = new QUdpSocket();
    so->bind(port);
    this->exec();
    so->deleteLater();
}

To copy to clipboard, switch view to plain text mode 

As a result, the QUdpSocket *so lives in its own thread.
Is there some way to run reconnect() slot inside this same thread, where the run() function and UdpSocket *so live in? Otherwise the bind to another port isn't allowed:

QSocketNotifier: Socket notifiers cannot be enabled or disabled from another thread
QObject: Cannot create children for a parent that is in a different thread.

I've tried a lot. Always ending with running the SLOT reconnect() inside the SIGNALs thread.

Please, give me any suggestion, because I stuck out of ideas - since days now.
