MouseDoubleClickEvent on a QGraphicsScene

[scascio]

Using standard C++, you can use dynamic_cast :

YourGraphicsItem * item = dynamic_cast<YourGraphicsItem*>(items(event->scenePos()).last());
if(item) {
  //do your stuff
}

YourGraphicsItem * item = dynamic_cast<YourGraphicsItem*>(items(event->scenePos()).last());
if(item) {
  //do your stuff
}

I know Qt provides its own object cast, but I don't use them
