QThread not running in different thread

[lauwe]

I am trying to create a thread with an object inside it that does some work periodically (using a QTimer). My idea was to subclass QThread and have all communication as well as the timed event run through the event-loop. But with my current example, everything seems to still run in the same thread.

This is the thread-class.

class thread : public QThread
{
  Q_OBJECT
 
 private:
  QTimer *_timer;
 
 public:
  void run(void);
 
 public slots:
  void startTimer(int timeout);
  void _timeout(void);
 
};
 
void
thread::run(void) {
/* start the event-loop */
  exec();
}
 
void
thread::startTimer(int timeout) {
  if(!_timer)
    _timer = new QTimer();
 
      QObject::connect(_timer, SIGNAL(timeout()), this, SLOT(_timeout()));
 
  _timer->setInterval(timeout);
  _timer->start();
}
 
void
threadn::_timeout(void) {
  qDebug() << "timeout from" << QThread::currentThreadId();
}

class thread : public QThread
{
  Q_OBJECT

 private:
  QTimer *_timer;

 public:
  void run(void);

 public slots:
  void startTimer(int timeout);
  void _timeout(void);

};

void
thread::run(void) {
/* start the event-loop */
  exec();
}

void
thread::startTimer(int timeout) {
  if(!_timer)
    _timer = new QTimer();

      QObject::connect(_timer, SIGNAL(timeout()), this, SLOT(_timeout()));
   
  _timer->setInterval(timeout);
  _timer->start();
}

void
threadn::_timeout(void) {
  qDebug() << "timeout from" << QThread::currentThreadId();
}

This is what I run from my 'main' thread:

MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::MainWindow)
{
  ui->setupUi(this);
 
  thread *t = new thread();
 
  QObject::connect(this, SIGNAL(startTimer(int)), t, SLOT(startTimer(mode,int)), Qt::QueuedConnection);
  t->start(QThread::HighestPriority);
 
  qDebug() << "Hello from " << QThread::currentThreadId();
 
  emit startTimer(1000);
}

MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::MainWindow)
{
  ui->setupUi(this);

  thread *t = new thread();

  QObject::connect(this, SIGNAL(startTimer(int)), t, SLOT(startTimer(mode,int)), Qt::QueuedConnection);
  t->start(QThread::HighestPriority);

  qDebug() << "Hello from " << QThread::currentThreadId();

  emit startTimer(1000);
}
