> Issue Type: Improvement
> Components: .Unspecified - Framework
> Affects Versions: Apache Flex 4.10.0
> Environment: Gui framework
> Reporter: David Lantier

> It would be more safe and faster if it was possible to override the function UIComponent::removedFromStageHandler (and also, remove) instead to have to add and remove events listeners for those who extends UI classes.
> Have to check if new proposed method name "removedFromStage" not used by any component, or choose another.
> Example:
> private function removedFromStageHandler(event:Event):void
> {
> _systemManagerDirty = true;
> removedFromStage(); // proposition: add this call
> }
> // proposition: new function protected, dedicated to override
> /** Override this allow to be called when this is removing from stage. Avoids to have to listen REMOVED_FROM_STAGE event. */
> protected function removedFromStage():void {}
