The ISharedDisplayObject interface defines the minimum requirements that a DisplayObject must implement to be shared between IGraphicElement objects. The Group class uses the ISharedDisplayObject interface to manage invalidation and redrawing of sequences of IGraphicElement objects that share a DisplayObject.

Typically, when implementing a custom IGraphicElement class, you also implement this interface for the DisplayObject that the custom IGraphicElement creates.

property
redrawRequested:Boolean

Language Version: ActionScript 3.0
Product Version: Flex 4
Runtime Versions: Flash Player 10, AIR 1.5

Contains true when any of the IGraphicElement objects that share this DisplayObject need to redraw. This property is used internally by the Group class and you do not typically use it. The Group class sets and reads back this property to determine which graphic elements to validate.
