So, I've been working with the DragManager for a bit now, and I'm
wondering whether or not what I've found was a design decision or simply
an omission. Cosnider the case of having a mouseEnabled="false"
component (in my case a Canvas) lying on top of a drag target. The
following few lines of code (DragProxy.as 357-366):
// targetList is in depth order, and we want the top of the list.
However, we
// do not want the target to be a decendent of us.
var targetIndex:int = targetList.length - 1;
while (targetIndex >= 0)
{
newTarget = targetList[targetIndex];
if (newTarget != this && !contains(newTarget))
break;
targetIndex--;
}
ignores the mouseEnabled state, and the subsequent code fires the
DRAG_OVER event on the topmost non-selfcontained child in spite of
whether it should be receiving events. Now this could be easily solved
(the way I'm doing it) by overriding the appropriate function to check
for mouseEnabled, or to add a new property to InteractiveComponent like
isDragEnabled (since dragEnabled is used elsewhere for a different
scope), but I'm curious as to whether I'm missing an underlying
architectural decision.
