-/**
- *
- * Class <code>DragSource</code> defines the source object for a drag and drop transfer.
- *
- * IMPORTANT: This class is <em>not</em> intended to be subclassed.
- *
- * <p>This class defines the following items:<ul>
- * <li>the <code>Control</code> that the user clicks on to intiate a drag;
- * <li>the data that will be transferred on a successful drop;
- * <li>and the modes (move, copy, link) of transfer that are allowed.
- * </ul></p>
- *
- * <p>You may have several DragSources in an application but you can only have one DragSource
- * per Control. Data dragged from this DragSource can be dropped on a site within this application
- * but it can also be dropped on another application such as an external Text editor.</p>
- *
- * <p>The application supplies the content of the data being transferred by implementing the interface
- * <code>DragSourceListener</code> which uses the class <code>DragSourceEvent</code>.
- * The application is required to take the appropriate action to remove the data from the drag source
- * when a successful move operation occurs.</p>
- *
- * <code><pre>
- * // Enable a label as a Drag Source
- * Label label = new Label(shell, SWT.NONE);
- * // This example will allow text to be dragged
- * Transfer[] types = new Transfer[] {TextTransfer.getInstance()};
- * // This example will allow the text to be copied or moved to the drop target
- * int operations = DND.DROP_MOVE | DND.DROP_COPY;
- *
- * DragSource source = new DragSource (label, operations);
- * source.setTransfer(types);
- * source.addDragListener (new DragSourceListener() {
- * public void dragStart(DragSourceEvent e) {
- * // Only start the drag if there is actually text in the
- * // label - this text will be what is dropped on the target.
- * if (label.getText().length() == 0) {
- * event.doit = false;
- * }
- * };
- * public void dragSetData (DragSourceEvent event) {
- * // A drop has been performed, so provide the data of the
- * // requested type.
- * // (Checking the type of the requested data is only
- * // necessary if the drag source supports more than
- * // one data type but is shown here as an example).
- * if (TextTransfer.getInstance().isSupportedType(event.dataType)){
- * event.data = label.getText();
- * }
- * }
- * public void dragFinished(DragSourceEvent event) {
- * // A Move operation has been performed so remove the data
- * // from the source
- * if (event.detail == DND.DROP_MOVE)
- * label.setText("");
- * }
- * });
- * </pre></code>
