I have tried extending the TreeItemRenderer class similar to your
example, the problem that I have is that the item is still rendered
by a single label. It's not clear to me how I can create a more
complex item renderer, for example, one that consists of a label and
an image.
Is there a way to do this in flex 2 short of writing a custom
renderer that handles it's own indentation and controls?
Thanks.
