		onCurrentIndexChanged: 
        {      
        
            if(swipView.currentIndex === 0)
            {
                // change pgRect.state
            }
        
        }
    }
}

i want to have access to rectangle properties and change its state (changing the qml page loaded on rectangle) in onCurrentIndexChanged signal.
but it says: pgRect is not defined.
