[jira] [Updated] (FLEX-33740) Change UIComponent private function removedFromStageHandler 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 updated FLEX-33740:
---------------------------------

    Description: 
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 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. Avoid to listen REMOVED_FROM_STAGE event. */
protected function removedFromStage():void {}
