QGraphicsView::itemAt() always returns zero

So i created a few MyItem instances and addItem()ed then to my custom QGraphicsView. This works perfectly, and the widgets show up just fine.
However, the scene()->itemAt(...) functions returns always zero, when given the coordinates obtained from a QMouseEvent.

Code:

---

class MyItem: public QGraphicsProxyWidget
{
      MyItem() {
         setWidget(new SomeWidget());
       }
//...
};

---

Code:

---

void MyQGraphicsView::mousePressEvent( QMouseEvent *event )
{
	QGraphicsItem* itm = scene()->itemAt(event->pos()); //nope
        itm = scene()->itemAt(event->pos(), transform()); //nope
}

---

Now, i am still struggling with understanding all the transformation stuff :/, but to my understanding, nothing of that sort should be necessary here? Unfortunately, this seems to be a rarely used function, and i cant seem to find any proper examples.


Do i have to apply some magic to the coordinates before passing them to the function? What else could be wrong?

The coordinates are in viewport's coordinate space. You need to map that to the scene first.

i really need to do more reading on all this. thanks.
