@API(type=EXTENDABLE, src=PUBLIC) public interface AuthorDnDListener extends SWTExtension
AuthorDnDListener
class provides event notification to the author extension
for DropTarget events.
As the user moves the cursor into, over and out of the author editor page, events indicate what operation can be performed and what data can be transferred if a drop where to occur at that point. The listener can respond to these events and change the type of data that will be dropped by modifying event.currentDataType, or change the operation that will be performed by modifying the event.detail field or stop any drop from happening on the current target by setting the event.detail field to DND_DROP_NONE.
When the user causes a drop to happen by releasing the mouse over the author editor page, the listener has one last chance to change the data type of the drop through the DropAccept event. If the drop is still allowed, the DropAccept event is immediately followed by the Drop event. In the Drop event, the listener can still change the operation that is performed but the data type is fixed.
