Class TransferHandler.SwingDropTarget

java.lang.Object
  java.awt.dnd.DropTarget
      javax.swing.TransferHandler.SwingDropTarget

All Implemented Interfaces:

DropTargetListener, EventListener, Serializable, UIResource

Enclosing class:

TransferHandler

static class TransferHandler.SwingDropTarget

extends DropTarget

implements UIResource

This is the default drop target for drag and drop operations if one isn't provided by the developer. DropTarget only supports one DropTargetListener and doesn't function properly if it isn't set. This class sets the one listener as the linkage of drop handling to the TransferHandler, and adds support for additional listeners which some of the ComponentUI implementations install to manipulate a drop insertion location.
