c++ - Events with QGraphicsItemGroup

In my application I want to use QGraphicsItemGroup for grouping items into one item.
I played with it a little and not sure using it because when I want to catch events, events are merged together but I want to handle specific event with specific child.
How can I achieve this?

You need to call QGraphicsItemGroup::setHandlesChildEvents(false). This stops the QGraphicsItemGroup trying to handle the event, and lets the child QGraphicsItems handle them instead.
