This method is responsible for undertaking
the transfer of the data associated with the
gesture. The DropTargetDropEvent
provides a means to obtain a Transferable
object that represents the data object(s) to
be transfered.
From this method, the DropTargetListener
shall accept or reject the drop via the
acceptDrop(int dropAction) or rejectDrop() methods of the
DropTargetDropEvent
parameter.
Subsequent to acceptDrop(), but not before,
DropTargetDropEvent
's getTransferable()
method may be invoked, and data transfer may be
performed via the returned Transferable
's
getTransferData() method.
At the completion of a drop, an implementation
of this method is required to signal the success/failure
of the drop by passing an appropriate
boolean
to the DropTargetDropEvent
's
dropComplete(boolean success) method.
Note: The data transfer should be completed before the call to the
DropTargetDropEvent
's dropComplete(boolean success) method.
After that, a call to the getTransferData() method of the
Transferable
returned by
DropTargetDropEvent.getTransferable()
is guaranteed to
succeed only if the data transfer is local; that is, only if
DropTargetDropEvent.isLocalTransfer()
returns
true
. Otherwise, the behavior of the call is
implementation-dependent.
