Interested in knowing the exact reasoning behind it!!!

Hi,

I'm interested in knowing the reason for this.

@
" QObject::connect: No such slot QThread::StopedServiceThread<> in MyThread.cpp"
@

Even though I tried to debug the QT4.7.4 framework, but couldn't come with any conclusion.
@
//MyThread.h

#include <QThread>
#include<qobject.h>

class Mythread : public QThread
{
public:
Mythread(QObject *parent = 0);
~Mythread();

void setThreadFlag();
void setDelay();
void run();

private:
qint32 stopTheThread;

public slots:
void TerminateServiceThread();
void StopedServiceThread();
};

//MyThread.cpp

#include "Mythread.h"

Mythread::Mythread(QObject *parent)
: QThread(parent)
{

stopTheThread = false;
QObject::connect(this, SIGNAL(finished()), this, SLOT(StopedServiceThread()));
}

Mythread::~Mythread()
{

}

void Mythread::setThreadFlag() {
stopTheThread = true;
}

void Mythread::StopedServiceThread() {
printf("Thread stopped\n");
}

void Mythread::TerminateServiceThread() {

printf("Thread Got terminated \n");

}

//main.cpp

#include <QtCore/QCoreApplication>
#include "Mythread.h"

int main(int argc, char *argv[])
{
QCoreApplication a(argc, argv);

Mythread obj;

obj.start();

obj.setDelay();

obj.setThreadFlag();
return a.exec();
}

Your class should look like this :
@
class Mythread : public QThread
{
Q_OBJECT

...
}

Where is "Q_OBJECT":http://doc.qt.nokia.com/4.7/qobject.html#Q_OBJECT macro ?

Edit : You need Q_OBJECT macro, so that MOC (meta Object Compiler) will do the necessary to implement signals and slots . Refer "Meta-Object system":http://doc.qt.nokia.com/4.7/metaobjects.html#meta-object-system

The reason is simple if you don't have the Q_OBJECT macro, "the class will not be moc'ed":http://doc.qt.nokia.com/4.7/signalsandslots.html in moc_MyThread.cpp and the slots don't exist.
