[Qt-interest] QListView::scrollTo() problem

I might not see a problem, but according to my impression I know :P
It is 0.

Correct me if I am wrong.

All you need is to get notified when events started before are done.
So connecting modelReset() signal to your slot supposed to give you a good point to call QTimer::singleShot with 0 as a delay.

Best regards,
Alex

Yes, I thought about it and even tried. But I don't think it's a good
way because nobody can tell how much the delay should be.
