Returns true if this item handles child events (i.e., all events intended for any of its children are instead sent to this item); otherwise, false is returned.
This property is useful for item groups; it allows one item to handle events on behalf of its children, as opposed to its children handling their events individually.
The default is to return false; children handle their own events. The exception for this is if the item is a QGraphicsItemGroup, then it defaults to return true.
