In a List-based control, what is the easiest way to suppress the drop accept/unaccept icons from appearing? Specifically, the "green plus sign" and the "red X".
I have found examples that recommend calling DragManager.showFeedback(DragManager.NONE) to overridden dragStartHandler and dragOverHandler methods yet this doesn't seem to work.
As a follow-up to this, I have found that I can override dragOverHandler:
override protected function dragOverHandler(event:DragEvent):void
This gives me a reasonable approximation of what I am looking for. However, I would expect that when I call DragManager.showFeedback(DragManager.NONE), no indicator shows up - however, the "Red X" appears.
Also, I cannot find documentation anywhere regarding how I can customize and create my own "Green Plus" and "Red X".
