How do I allow objects "accept drops"

[MrSteve]

I am trying to re-write the DragNDropList widget. I would like to be able to have it accept any object dropped onto it (similar to "accept drops" in Etoys).

So two questions:

1) How can I detect another object being "dropped" onto the my widget?

The thought being then add the dropped object to my widget's parts using:

Code: Select all

self_addPart (id <object dropped>)

Then once I add that "part" the next question is how to I move it? The existing "Motion" blocks only seem to allow sending to "this".

2) Is there a way to create "droppable behaviors?"
Ie: I could implement what I want by allowing certain behaviors to be dropped onto to other objects.
