Disabling the moving handler makes sense when you need only the transformed positions of the nodes inside a container. If you specify disableHandler as true, there will be no action when the user tries to drag a node. However, there is a purpose behind this. The newly created MoveContainer offers you a method to access the nodes (which now are absolute positioned) and you can move them based on your algorithm.
There is a basic demo in this page that will make you understand what I am talking about. Combined with the restore() method of the MoveContainer it offers you the possibility to generate some movement and then restore everything to the initial state
The getElements() function will return you the array of the MoveElement objects. Each of these objects contains a reference to the element moved (in the .id member). So iterating through the array and modifying its content will result in afecting the elements inside the container
function move(c) { MoveContainer(c, false, true); }</script>
function getList(c) { var wC=c.__wrapperContainer; if(wC) return wC().getElements(); else return null; }</script>
