Rails spinoffs - Jun 2006 - Drag''n''drop DOM elements between (I)FRAMEs

I am quite disappointed in the drag ''n'' drop support in
Mozilla Firefox.
What am trying to achieve is dragging an element from one IFRAME/FRAME into 
another IFRAME/FRAME. But upon dropping the element, I do not want the 
target IFRAME/FRAME to open/load it. I want it simply to handle the event, 
such as parsing the element/data dropped. Such uses as dropping an element 
into a table inbetween rows 2 & 3.

I have studied Netscapes way of ondragdrop events. However this only handles 
dropping external files, into the browser window, and the browser window 
will open/load the file. This is not what I want.

The only closest IE/FF drag''n''drop thing I found was
http://script.aculo.us/
however their dragging doesn''t go across IFRAME/FRAMEs.

Is there any way to implement scriptaculous/rails to do something similar 
drag''n''drop events as IE''s:

ondragenter, ondragleave, ondragover, ondrop? that works across 
IFRAME/FRAMEs?

No, you cannot do that. Dragging into window instances across others 
should not allow this for security reasons anyhow. It would be cool 
though, as then you could drag draggables from one window to another. 
This has nothing to do with Mozilla Firefox.

I have *heard* of people doing this by using the parent window to  
store and mediate state between the 2 child iframe windows. So when a  
drag was in progress, and the mouse coord reached the edge of the  
iframe window, you would notify the other iframe to start listening  
for mouseover events and create the illusion of a seamless "drag". But
I''ve never actually seen it done - and as you can imagine it would be  
prone to all kinds of problems with missed events.

Also, it should go without saying that all partipating documents would  
have to be under the same domain.
