WheelEvent reimplementation of a class derived from QGraphicsView

[wysota]

I mean trying to override the method wouldn't work. Your method simply could never be called.

I admit I have no idea what you are trying to do, it seems obvious to try it this way:

void Cls::wheelEvent(...) {
  qreal sc = item->scale();
  if(wheel goes up) sc+= 0.1; // or whatever
  else if(wheel goes down) sc -= 0.1;
  item->setScale(qBound(0.1, sc, 2.0));
}

void Cls::wheelEvent(...) {
  qreal sc = item->scale();
  if(wheel goes up) sc+= 0.1; // or whatever
  else if(wheel goes down) sc -= 0.1;
  item->setScale(qBound(0.1, sc, 2.0));
}
