83 * CAUTION: this method supposes that before its call, a call to prepareGeometryChange() hase been
84 * done for the BoxItem that owns this InterfaceItem, so that the scene will readraw automatically
85 * the BoxItem. For the connections, the call to prepareGeometryChange() is done within setPath()
86 * that is called in this method. Thus, there is no need to call update() after the termination of
