Justin Mclean updated FLEX-27291:
---------------------------------
Labels: performance (was: )
> Redundant code in Scroller: orientation change handler
> ------------------------------------------------------
>
> Key: FLEX-27291
> URL: https://issues.apache.org/jira/browse/FLEX-27291
> Project: Apache Flex
> Issue Type: Bug
> Components: Spark: Scroller
> Affects Versions: Adobe Flex SDK Previous
> Environment: Affected OS(s): All OS Platforms
> Language Found: English
> Reporter: Adobe JIRA
> Labels: performance
>
> Found in version: Hero i6 (prerelease)
> orientationChangeHandler seems to be redundant, since the scroll positions
> depends on scroller/viewport properties (height, contentHeight, etc), not
> something top and global like device orientation. This brings undesirable
> dependencies and affects the performance a bit (since it would make double
> proccessing on orientation change and on component properties change).
> Solution: remove everything regarding orientation.
> If someone will point on checkScrollPosition() and how orientation change
> affects stopping throwEffect and snapping — it makes more sense to
> distinguish between viewport's content resize and scroller resize to achieve
> that. But not the orientation. The code smells... like _global variables.
