Custom widgets can now implement their own effects by extending the DragSourceEffect class and the DropTargetEffect class.

The source effect can be specified for a drag source by calling DragSource.setDragSourceEffect(DragSourceEffect) and the "drag under effect" can be specified for a drop target by calling DropTarget.setDropTargetEffect(DropTargetEffect).

For example, the drag source image can be specified by the user as follow:

	StyledText text1 = new StyledText(shell, style);
	DragSource source = new DragSource(text1, DND.DROP_COPY);
	source.setDragSourceEffect(new DragSourceEffect(text1) {
		public void dragStart(DragSourceEvent e) {
			e.image = display.getSystemImage(SWT.ICON_WARNING);
		}
	});

Similarly, the drag-under-effect on the target can be specified as follow:

	StyledText text2 = new StyledText(shell, style);
	DropTarget target = new DropTarget(text2, DND.DROP_DEFAULT | DND.DROP_MOVE | DND.DROP_COPY | DND.DROP_LINK);
	target.setDropTargetEffect(new DropTargetEffect(text2) {
		public void dragOver(DropTargetEvent event) {
			//TODO: provide your own effect when an item is dragged over the StyledText
		}
	});

Also see TableDragSourceEffect, TableDropTargetEffect, TreeDragSourceEffect, TreeDropTargetEffect and StyledTextDropTargetEffect for examples of some default effects for Table, Tree and StyledText.
