[REG Qt 4] Resizing the main widget in showEvent() before it's visible moves it to upper left corner

 void myWidget::showEvent(QShowEvent * event)
{
 if (event->type()==QEvent::Show) {
  resize (200,200);
 }
}

 void myWidget::showEvent(QShowEvent * event)
{
 if (event->type()==QEvent::Show) {
  QTimer* timer = new QTimer(this);
  timer->setSingleShot(true);
  QObject::connect(timer, &QTimer::timeout, [timer]() {
   resize(200,200)
   delete timer;
   });
 timer->start(0);
 }
}
