Drop onto tab - possible?

I'm using Isomorphic SmartClient/SmartGWT Framework (v9.0p_2013-09-17/Pro Deployment 2013-09-17)

I have a tabset and I'm trying to figure how I can drag and drop onto the tab in the tabset. I cant find anything on the tab or tabset like canAcceptDrop(). Is this even possible? Essentially, I just want to be able to drop something onto the tab and get the event then do something with it. I thought that if I could get a handle to the tab top piece (not sure of the right name for that) then maybe I could find something that I could call canAcceptDrop() on.

Oh - one other thing... I'd like to be able to drag a tab onto another tab too so I can get the event and do something with it.

Basically, I'm trying to allow the user to associate the object shown in one tab with the object in another tab.


Thoughts? Ideas?

Thanks,
Brian
