public final class TextWindowDropTargetEffect
extends DropTargetEffect

This class extends SWT's DropTargetEffect (which provides no visual feedback) for TextWindow. It provides a drag-under effect (set drop position and scroll) during a DND drop-hoverin' taking place over a TextWindow. The class has the same API as (extends) DropTargetAdapter, so that it can provide custom visual feedback when a DropTargetEvent occurs.
