Problems with a Thread

Hi

I tried to restart a thread (after exit them), but when I push the restart button the program crashed and the debuger showed the following message: "QObject: Cannot create children for a parent that is in a different thread.(Parent is QTcpSocket(0x811a274), parent's thread is QThread(0x81367c0), current thread is OptimizationThread(0x81a6d90)"

What could be the problem?

The code to restart is this:

Code:

---

pause = false;
    if (!isRunning())
    {
        start(QThread::LowPriority);
    }
    else
    {
        condition.wakeOne();
        quit();
        if (!isRunning())
        {
            start(QThread::LowPriority);
        }
        else
        {
            qDebug()<<"Error";
        }
    }

---

I use Qt 4.4.3 and ubuntu

Could you show more code? You've got a bug there, but it's hard to say without seeing more code. Be especially careful with slots in QThread subclasses. You can search the forums for more details on the subject.

Ok, I Attach the code for the thread and the dialog uses this thread. :)

Thanks you

Ok, how about defining QT_FATAL_WARNINGS=1 environment variable and getting the backtrace from a debugger?
