Cocos2d-x V3 Alpha - how to set priority of menu

Hi,

I currently have a layer with menu buttons, then a layer on top, then a further layer with menu buttons on top of that. I previously disabled the bottom layer menu buttons by swallowing touches in the middle layer and setting it and the top layer to a higher priority. However ever i can no longer seem to get the current touch priority of the menu nor set them as required. Any ideas how to get/set a menu’s touch priority?
