I have managed to drop items from outside the tree onto it,
but the problem remains. When I enable the tree to receive dropped
data I need to create custom handlers for the D&D events, but
by doing so I override the default event handlers that enable
D&Ding inside the tree itself... Now, is there a way to
redirect the events to the default handlers when an local (inside
the tree) D&D is taking place or do I have to replicate the
default behavior in my custom handlers?
