Hi Tracy, thanks for the idea. But this solution doesn't work for me either.
I assume this function resides in a custom image class so you can pass "this" as drag initiator. In this case an image (thats already loaded - so you can access this.content without any problems). But if I try to load a image with the loader class... wait for the Event.COMPLETE and try to use image.content it doesn't show up. Very strange. This drives me really crazy. --- In flexcoders@yahoogroups.com, "Tracy Spratt" <tspr...@...> wrote: > > I found this post just the other day, and it appears to bear on your > issue: > > http://www.arlingtondev.com/thoughts/?p=17 > > > > But I cannot figure out how it would work.
