A DESCRIPTION OF THE REQUEST :
The BasicTreeUI installListeners() method directly instantiates a TreeDropTargetListener to respond to DropTarget events.  The rest of the installListeners() method use factory methods to add a level of indirection in creating these listener classes.


JUSTIFICATION :
A factory method should be used for TreeDropTargetListener too to allow custom L&Fs to provide custom TreeDropTargetListener.

The pattern of using factory methods should be part of the L&F coding standards.


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
I'd like to see a createDropTargetListener() method in BasicTreeUI with installListeners() calling it.

CUSTOMER SUBMITTED WORKAROUND :
The workaround is to copy the BasicTreeUI installListeners() method to BasicTreeUI subclass and change the creation of TreeDropTargetListener to desired class.

N/A

The fixes for 4468566 and 4942851 will re-architect Swing's drop support to make it much more usable by the developer. In particular, they will provide location sensitive dropping, and much better indication of the drop location. As a result of this re-architecture, BasicTreeUI will no longer install a drop target listener, as all the details of indicating drop locations will be handled within TransferHandler. Closing as a duplicate.
