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.

RE: [flexcoders] Layered ListBase component
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.

Re: [flexcoders] Layered ListBase component
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. Loud Jazz wrote: Thanks.

Re: [flexcoders] Layered ListBase component
I've implemented something similar on a project. You need to define dragEnter, dragExit,dragDrop events like so: addEventListener(DragEvent.DRAG_ENTER, dragEnterHandler); addEventListener(DragEvent.DRAG_EXIT, dragExitHandler); addEventListener(DragEvent.DRAG_DROP, dragDropHandler); And in your dragEnterHandler you can 'accept' the drag and on dragDropHandler add a child to your canvas based on the data being dragged in. A great tutorial: http://www.adobe.com/devnet/flex/quickstart/adding_drag_and_drop/ On Wed, Nov 18, 2009 at 11:08 AM, Jeffry Houser j...@dot-com-it.com wrote: The Scrap blog canvas is most likely... well, a canvas or container.

[flexcoders] Layered ListBase component
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
Re: [flexcoders] Layered ListBase component
I guess I don't understand the request. Don't most list based classes allow you to drag and drop items in them and then position those items where they were dropped? When you say depth, I'm unclear what you are referring to. method_air wrote: 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).
