The ILayoutManagerClient interface defines the interface that a component must implement to participate in the LayoutManager's commit/measurement/layout sequence.

Objects that implement this interface can be passed to the LayoutManager's invalidateProperties() method. When the LayoutManager reaches the commit properties phase, the LayoutManager invokes this object's validateProperties() method.

Similarly, if an object is passed to the LayoutManager's invalidateSize() method, then the LayoutManager calls that object's validateSize() method during its measurement phase, and if an object is passed to LayoutManager's invalidateDisplayList() method, then the LayoutManager calls its validateDisplayList() method during the layout phase.

The ILayoutManagerClient interface is implemented by the UIComponent and ProgrammaticSkin classes.

Public Properties

	Property		Defined By

		nestLevel : int The top-level SystemManager has a nestLevel of 1.	ILayoutManagerClient
		processedDescriptors : Boolean Set to true after immediate or deferred child creation, depending on which one happens.	ILayoutManagerClient

		addEventListener(type:String, listener:Function, useCapture:Boolean = false, priority:int = 0, useWeakReference:Boolean = false):void Registers an event listener object with an EventDispatcher object so that the listener receives notification of an event.	IEventDispatcher
		dispatchEvent(event:Event):Boolean Dispatches an event into the event flow.	IEventDispatcher
		hasEventListener(type:String):Boolean Checks whether the EventDispatcher object has any listeners registered for a specific type of event.	IEventDispatcher
		removeEventListener(type:String, listener:Function, useCapture:Boolean = false):void Removes a listener from the EventDispatcher object.	IEventDispatcher
		validateDisplayList():void Validates the position and size of children and draws other visuals.	ILayoutManagerClient
		validateProperties():void Validates the properties of a component.	ILayoutManagerClient
		validateSize(recursive:Boolean = false):void Validates the measured size of the component If the LayoutManager.invalidateSize() method is called with this ILayoutManagerClient, then the validateSize() method is called when it's time to do measurements.	ILayoutManagerClient
		willTrigger(type:String):Boolean Checks whether an event listener is registered with this EventDispatcher object or any of its ancestors for the specified event type.	IEventDispatcher
