QSplashScreen Weirdness

[wysota]

I'd suggest doing it a bit another way. You need to implement your functionality in a slot that can be called multiple times - once for every iteration. Then create the progress dialog, make a connection between a single shot timer and your slot and call exec() on the dialog.

Set a 0 timeout for the timer and at the end of your slot start a 0-timeout single shot timer again. Something like:

QProgressDialog dlg(this);
iteration = 0;
startSlot();
dlg.exec();
//...
void X:startSlot(){
  iteration++;
  if(iteration<1000)
    QTimer::singleShot(0, this, SLOT(startSlot()));
}

QProgressDialog dlg(this);
iteration = 0;
startSlot();
dlg.exec();
//...
void X:startSlot(){
  iteration++;
  if(iteration<1000)
    QTimer::singleShot(0, this, SLOT(startSlot()));
}

The main idea is to make sure you call exec on the progress dialog. See if your app crashes then.
