The type of data that can be transferred is specified by subclasses of Transfer such as - * TextTransfer or FileTransfer. The type of data transferred can be a predefined system type or it - * can be a type defined by the application. For instructions on how to define your own transfer type, - * refer to <code>ByteArrayTransfer</code>.</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 - * or it can 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 - * <code>DragSourceListener</code> and associating it with the DragSource via DragSource#addDragListener.</p> - * - * <p>When a successful move operation occurs, the application is required to take the appropriate - * action to remove the data from its display and remove any associated operating system resources or - * internal references. Typically in a move operation, the drop target makes a copy of the data - * and the drag source deletes the original. However, sometimes copying the data can take a long - * time (such as copying a large file). Therefore, on some platforms, the drop target may actually - * move the data in the operating system rather than make a copy. This is usually only done in - * file transfers. In this case, the drag source is informed in the DragEnd event that a - * DROP_TARGET_MOVE was performed. It is the responsibility of the drag source at this point to clean - * up its displayed information. No action needs to be taken on the operating system resources.</p> - * - * <p> The following example shows a Label widget that allows text to be dragged from it.</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;

- * } - * }; - * 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("");
