Stage Flash Class

The Stage class is the area in the Flash player that all of the content is rendered into. The Stage is the root of the display list. Other components will be rendered in the normal render loop only if they are children or descendants of the Stage class.

Stage is a DisplayObjectContainer class and supports the normal methods of addChild(child:DisplayObject) and removeChild(child:DisplayObject). Outside of these methods, however, many of the properties of DisplayObject to not apply to the Stage since it has no rendering by itself.

You can access the Stage from any component that is part of the display list hierarchy. When a class is added to the display list it will receive the addedToStage event and thereafter its stage property will reference the Stage it has been added to.
