The Scrap blog canvas is most likely... well, a canvas or container.
Dragging items from a list onto the canvas would just be like adding a
new child to the canvas [I presume]. I've used scrap blog very little,
but I would not be surprised if they have wrote a "Z-order manager"
style class to control what shows on top of other things.
If you drag an item off the list based class, I Would expect the
selectedIndex would reset to -1; the unselected state.

Thanks. The component I'm looking for can be found at scrapblog.com,
the user can drag and drop items from the list onto the 'canvas'. The
items can overlap and layer. Presumably when adding a new layer, the
corresponding bound object in the data provider is at the highest index.

Subject: Re: [flexcoders] Layered ListBase component
As far as I can tell, List does almost exactly what you are after. The
only caveat is your last sentence 'The depth of the display objects is
bound to the data provider indexing.'.
The ItemRenderers of all List controls are re-used within the control,
so the display objects are not at all connected to the index. Nor
would you want to, if you had hundreds or thousands of items in your
control. It seems as though this is a somewhat surmountable issue.
Check out the 'dragEnabled', 'dropEnabled' and 'dragMoveEnabled'
properties of the list controls for more information.

Hello,
I am looking for a component (presumably extending ListBase) that
allows objects to be dropped inside of it, and positioned where
they are dropped (kind of like a stage or root timeline). The
depth of the display objects is bound to the data provider indexing.
Does such a component exist?
Thanks,
Philip
