ScribbleDragAndDrop.java example

comment out the code starting with // Choose a cursor based on the type of the drag the user initiated Cursor cursor End the comment after the switch statement. Then, near the bottom of the page, there are two calls to startDrag(). In each one, replace "cursor" with "null". By passing null instead of a cursor, the system will automatically supply a default cursor, and will automatically upated it as needed if the drop action changes during the drag.

last method call on the page

If you try the example using the book's code the Drag and Drop always results in a Move, not a Copy. This is because the drop method needs to give a feedback as to which drop action was performed. The method DropTargetDropEvent.acceptDrop needs to be passed the correct action (and not ACTION_COPY_OR_MOVE). For instance: e.acceptDrop(e.getDropAction());
