I did something similar, but I took an element of one type from a list
and dropped it onto a canvas and then converted it to another type.
This was done by just accepting the data type that gets dropped in the
doDragDrop function and converting it in there before adding it. The odd
thing is how it's in the "items" list. I believe that hung me up for a
while. Anyway, check out the code, which I think is pretty much a rip
from the docs. This code is from my receiving canvas.
private function doDragEnter(event:DragEvent):void
{
var dropTarget:Canvas = event.currentTarget as Canvas
DragManager.acceptDragDrop(dropTarget);
}
private function doDragDrop(event:DragEvent):void
{
var dropTarget:Canvas = Canvas(event.currentTarget);
var items:Array =
event.dragSource.dataForFormat("items") as Array;
if (!(event.dragSource.hasFormat("items")))
{
trace("stop");
}
for (var i:int = 0; i<items.length; i++)
{
//This is the other data type. The addCard
method is akin to your factory.
var card:CardView = addCard(items[i]);
card.x = this.mouseX;
card.y = this.mouseY;
}
}
