Jake, I cannot use bitmapdata because i'll have to use an instance of itemrenderer which will have some different display behavior when used as proxy.
I've managed to get a transparent bg, I had to set explicitly in css class applied to the *list* (because proxied itemrenderer use "styleName=List(owner);") : > background-color: ''; > BTW, "selection-color" set to empty string draws a black bg... thomas --- http://www.web-attitude.fr/ msn : [email protected] softphone : sip:[email protected] <sip%[email protected]> téléphone portable : +33601 822 056 2009/5/26 Jake Churchill <[email protected]> > > > > http://www.axelscript.com/2008/03/26/creating-a-dragimage-from-your-uicomponent/ > > > > This is a blog post a friend of mine wrote about this.
