Re: [flexcoders] Is there a way to tell flash NOT to render a certain area?
right. its for lazy loading. when the scroll thumb goes into the hot area
then it sends requests to the server for new content. when new content is
received i create a new container and add it to the accordion with
addChildAt(newContainer, 0); to make sure it is before existing content. to
keep a natural feel the view should stay where it is, where the user has the
mouse down on the scroll thumb.
code example. this isn't showing lazy loading. it is only showing that when
adding a container before exiting content that new container is selected

When you scroll left you get to a location where more items are added. As
you add each item the scrollbar thumb track jumps to the right and then
jumps back to where the mouse is. This happens every time a new item is
added to the accordion.

Re: [flexcoders] Is there a way to tell flash NOT to render a certain area?
I think what I'm looking for is a way to have it not apply any updates for a few frames. In the same way includeInLayout set to false causes it to be skipped in the layout, something similar to prevent any updates to scroll position.

Re: [flexcoders] Is there a way to tell flash NOT to render a certain area?
I’m still lost. Are you trying to control the wrapping Scroller’s scrollbar or is there a scrollbar in your Haccordion? I think I would build one into the Haccordion that knows how many children exist. That’s how List and others handle virtualized renderers.

Re: [flexcoders] Is there a way to tell flash NOT to render a certain area?
that makes sense. i wanted to make sure there wasn't any other options before working on that. ps the scroller scrollerbar. the mxml example doesn't show that.
