Hi, everybody!
I use ViewerDropAdapter to add drop support to my view.But if I try to drop
for the first time no drop operation is available (I see this crossed circle
no matter where I am trying to drop) until I press CTRL, only then the
behaviour of drop seems to be ok. But how do I switch to move operation? In
normal situation I use CTRL to switch between copy and move. But how do I do
it here?
And how to I start withh copy operation, not with NONE operation.
thanks a lot in advance for your help.

Anyway, Paul, Now it works the way it should be.
What I did wrong is - in my drag source I did not add MOVE operation, just
copy.
Now what I am doing is just overload operation dragOver and when drop is not
allowed I set
event.detail = DND.DROP_NONE;
otherwise I am doing nothing and it works fine.
hope this helps.
