[jira] [Closed] (FLEX-33740) Change UIComponent function removedFromStageHandler from private to protected to allow override

["David Lantier (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/FLEX-33740?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

David Lantier closed FLEX-33740.
--------------------------------

    Resolution: Won't Fix

Override removeFromStage was an idea to simplify Flex framework utilisation. This goal remains possible, but we have to deal a lot more to provide an "override callback" as reliable as the event. I will take time to comeback with a proposition more robust if I can.

> 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 {}
