QThread movetoThread howto?

Reudi

Dear People of the Internet, I'm realy confused about the usage of QThread.
I got a little class which communicates over a SerialPort with a little robot.
So far so good. Sadly this class needs to wait for the robot to finish with the execution of his task.

So i got a small "commincation class"

//conenction Object
class SerialConnection: public QObject
{
    Q_OBJECT
    public:
        explicit SerialConnection( QObject *parent = 0);
        virtual ~SerialConnection();

       //evil Method which needs alot of time to executed and needs to be threaded
        int move(QPoint);

     //other evil Method needs alot of time
     int concurWorld(bool showMercy);
}

I got a main class which calls the "move" and concurWorld methods. Those Methods wont be called at the same time.
All i want to do is to Call those methods in a Thread so it doesnt block my main appplication.
Somehow it should work like this

void mainClass::callmove()
{
    QThread * thread = new QThread();
    SerialConnection  * serial  = new SerialConnection();
   serial->moveToThread(thread);
 //at this point I got no clue how to continue

   
}

I know that i need to change the functions to Slots in my serialconnection class and i know that i can connect the start signal of the thread to one of those slots.
But how can i parse some arguments to those methods and how can i get the return values? And how can i connect both of them to a thread when there is only the start singnal of thread?
I feel so dump for asking such a question but the Internet itself seems to be split on deciding which is the right way to use QThreads.

Thanks for the help

class SerialConnection: public QObject
{
    Q_OBJECT
    public:
        explicit SerialConnection( QObject *parent = 0);
        virtual ~SerialConnection();
signals:
void moveReturned(int);
void concurWorldReturned(int);
public slots:
void runMove(QPoint val){emit moveReturned(move(val));}
void runConcurWorld(bool val){emit concurWorldReturned(concurWorld(val));}
private:
       //evil Method which needs alot of time to executed and needs to be threaded
        int move(QPoint);

     //other evil Method needs alot of time
     int concurWorld(bool showMercy);
}

void mainClass::callmove()
{
    QThread * thread = new QThread();
    SerialConnection  * serial  = new SerialConnection();
   serial->moveToThread(thread);
connect(thread, SIGNAL(finished()), thread, SLOT(deleteLater()));
connect(thread, SIGNAL(finished()), serial, SLOT(deleteLater()));
thread->start();

   
}

now you can use any signal connected to the 2 new slots to run it (or use QMetaObject::invokeMethod with Qt::QueuedConnection) and when the process is finished the object will emit the signal with the return value

Thank you kind Sir! I'll always be in your debt!
Cheers.
