[Qt-interest] remove QgRaphicsItem from parent

[Riccardo Roasio]

But it seems not to work..

i use this code:

  for(int i=0;i<elements.size();i++)
      {
        ReceiptElement *e=elements.at(i);
        e->~QGraphicsItem();
      }

and i think this will remove all elements from screen but they
continue to be displayed....

Also calling an update on the parent item after these actions doesen't
solve the issue

What i'm doing wrong?

Thanks,
Riccardo
