Qt Threading

[jpn]

Exactly. But you can easily work it around by creating another object which lives in the correct thread and move those slots there:

class ReconstructionObject : public QObject {
    ...
    public slots:
        void startMethod(int iToStart);
        void stopMethod(int iToStop);
 
    signals:
        void methodFinished();
};

class ReconstructionObject : public QObject {
    ...
    public slots:
        void startMethod(int iToStart);
        void stopMethod(int iToStop);
 
    signals:
        void methodFinished();
};

Then you have two options: 1) create ReconstructionObject in ReconstructionThread::run():

void ReconstructionThread::run()
{
    ReconstructionObject object;
    // connect signals and slots
    exec();
}

void ReconstructionThread::run()
{
    ReconstructionObject object;
    // connect signals and slots
    exec();
}

or 2) create it somewhere outside and use QObject::moveToThread():

ReconstructionThread* thread = new ReconstructionThread(parent);
ReconstructionObject* object = new ReconstructionObject;
object->moveToThread(thread);
thread->start();
 
// and for example something like this to handle cleanup
connect(object, SIGNAL(methodFinished()), object, SLOT(deleteLater()));
connect(object, SIGNAL(destroyed()), thread , SLOT(quit()));
connect(thread, SIGNAL(finished()), thread , SLOT(deleteLater()));

ReconstructionThread* thread = new ReconstructionThread(parent);
ReconstructionObject* object = new ReconstructionObject;
object->moveToThread(thread);
thread->start();

// and for example something like this to handle cleanup
connect(object, SIGNAL(methodFinished()), object, SLOT(deleteLater()));
connect(object, SIGNAL(destroyed()), thread , SLOT(quit()));
connect(thread, SIGNAL(finished()), thread , SLOT(deleteLater()));
