Interfacepublic interface IZOrderSupport extends flash.events.IEventDispatcher
Implementors DefaultZOrderSupport

This interface is used as model to store z-order information for IModelItems. If an implementation is returned by the graph lookup it is used by the GraphModelManager of any GraphCanvasComponent this graph is assigned to. The graph model manager compares the z-orders of model items in the same layer to decide in which order they shall be rendered.

public function getZOrder(item:IModelItem):int

The z-order of a model item determines its render order in comparison to other model items. Items having a smaller z-order are drawn behind those with higher z-orders. The rendering order of items having an equal z-order is undetermined.

Parameters

item:IModelItem

Returns
int
setZOrder()method 
public function setZOrder(item:IModelItem, order:int):void

Parameters

item:IModelItem
 
order:int

Event Detail
