i would like the label and message to be on the left of the icon....i would also like the icon to be right-aligned

what is the best way to do this? I'm confused by some of the tutorials i'm seeing for custom item renderers since they never explain how to format the renderer mxml, so i haven't figured that out yet although i suspect that's what i need to be doing
