How about the excuse/reason that we don't want to generate a renderer for every item in your dataprovider, and if they had variablerowheight, we'd never get the scrollbar parameters right?
We're going with a fractional approach but I'm not convinced of how smooth it will appear in all situations. That and time-to-implement are reasons it remains planned and not committed. ________________________________ From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of Troy Gilbert Sent: Thursday, June 14, 2007 1:34 PM To: [email protected] Subject: Re: [flexcoders] Flex 3 fractional scroll on List? Don't let Adobe off too easy on the "efficiency" excuse... they could have just as easily had smooth scrolling while still re-using item renderers, etc. For fixed-size item renderers it only requires one additional item renderer to be instantiated, and just a bit more code in the scroll bar handling. I think it's a bad oversight, or a bad business decision, because it makes an otherwise "slick" UI look archaic... come on, the AJAX guys have even go this stuff working (as does .NET!), so there's really no excuse (well, there are plenty of excuses, just no good *reasons*). It irks me to no end that one of the few complex components I'm using from the Flex framework in my current project is the HorizontalList (for thumbnails) and I'm stuck with the option of having to subclass (and who knows if the right vars are protected!) the control for just a fundamentally basic piece of "flash". But hey, they got so many other things "alright by me" that it's not exactly bringing down their average... it just sticks out like a sore thumb! ;-) Troy.

I understand the business case for the components working that way (they always have) to deal with a ton of data. But, from a usability and design perspective, if someone needs to display 'that' much data in a control, there's a problem with the design of the application in the first place. It's great to know it's planned! I'll keep an eye out on the nightly builds of the SDK to see what new things made it through. cheers, jon On Jun 14, 2007, at 4:12 PM, Alex Harui wrote: Still planned, not committed, not in this beta. ________________________________ From: [EMAIL PROTECTED] ups.com [mailto:flexcoders @yahoogroups.com] On Behalf Of Jon Bradley Sent: Thursday, June 14, 2007 1:09 PM To: [EMAIL PROTECTED] ups.com Subject: [flexcoders] Flex 3 fractional scroll on List? OK ... I can absolutely find zero information on this, either in the documentation or on the release notes. The only mention of it was in Matt Chotin's article on Adobe.com. I'm actually more interested in finding out whether or not Adobe added fractional / smooth scrolling to not only the List and DataGrid but the TileList as well. Anyone with an idea of these new implementations? I can't stand the current List functionality and would love to find a way around the cell-level scrolling if I can without re-writing a ton of code of course :). Right now I'm stuck with Tile and Repeater, which works but lacks a lot of functionality. cheers, jon
