Thanks Alex, This week I have been trying to optimize some of my item renderers and have been following your examples from the closet.
I have many IR's that have layouts 3 box's deep with view stacks to boot... Most of my IR's do custum selection indicators( border around thumbnails ect..) and these IR's are setting styles in creationComplete, show, and on ListEvent change and DataEvent change and I am trying to make it more efficient by following the component life cycle. Do you have a basic rule of thumb as to what you do in each faze like(this is my current understanding): commitProperties: update all display objects representing the model(data), I also have been trying(works with DataGrid) to perform custom selection indicators here(didnt work with TileList) measure: provide current measurement of all children updateDisplayList: just position children, can styles be changed here without forcing back through the cycle? Thanks for your help, Greg On Sat, Nov 14, 2009 at 1:08 AM, Alex Harui <[email protected]> wrote: > > > BTW, updateDisplayList should get called > > > > Alex Harui > > Flex SDK Developer > > Adobe Systems Inc. <http://www.adobe.com/> > > Blog: http://blogs.adobe.com/aharui > > > > *From:* [email protected] [mailto:[email protected]] *On > Behalf Of *droponrcll > *Sent:* Friday, November 13, 2009 9:44 PM > *To:* [email protected] > *Subject:* [flexcoders] Re: TileList custom ItemRenderer - > commitProperties not called when selection changes > > > > > > > > --- In [email protected] <flexcoders%40yahoogroups.com>, Greg > Hess <flexeff...@...> wrote: > > > > Hi All, > > > > I have a custom item renderer in one of my TileList's.
