Interface TransferDragSourceListener

All Superinterfaces:
  DragSourceListener, EventListener, SWTEventListener, TransferDragSourceListener

All Known Implementing Classes:
  AbstractTransferDragSourceListener

Deprecated. use org.eclipse.jface.util.TransferDragSourceListener instead

public interface TransferDragSourceListener
extends TransferDragSourceListener

A DragSourceListener that can handle one type of SWT `Transfer`. The purpose of a TransferDragSourceListener is to:

- Determine enablement for a Drag operation. Enablement is often a function of the current Selection and/or other criteria.
- Set data for a single type of Drag and Transfer.

`DelegatingDragAdapter` allows these functions to be implemented separately for unrelated types of Drags. DelegatingDragAdapter then combines the function of each TransferDragSourceListener, while allowing them to be implemented as if they were the only DragSourceListener.
