Do you mean like this?
syncro.h
#ifndef SYNCRO_H
#define SYNCRO_H
#include <QtCore>
#include "mythread.h"
class Syncro : public QObject
{
Q_OBJECT
public:
Syncro();
void Initialise(MyThread *);
public slots:
void jumpToFrame(int);
};
#endif // SYNCRO_H
Syncro.cpp
.
.
Syncro::Syncro()
{
setParent(QApplication::instance());
}
.
.
The setParent(QApplication::instance()) shows as an error in VS - incomplete
type is not allowed. Don't I have to specify the QApplication instance rather
than the class name?
Cheers...Paul

Can you try adding a constructor to Syncro, and add either
moveToThread(QApplication::instance()->thread());
or
setParent(QApplication::instance());
to it? I'm not sure if QObjects have a valid thread affinity by default.
