D27650: ItemContainer: disconnect signals in destructor

[Aleksei Nikiforov]

alnikiforov added a comment.


  Fix consists of following line:
  
    disconnect(this, &QQuickItem::parentChanged, this, nullptr);
  
  Two other disconnects are just in case of similar issues arising and for code consistency.
