| * |
| * <code>DragSource</code> defines the source object for a drag and drop transfer. |
| * |
| * <p>IMPORTANT: This class is <em>not</em> intended to be subclassed.</p> |
| * |
| * <p>A drag source is the object which originates a drag and drop operation. For the specified widget, |
| * it defines the type of data that is available for dragging and the set of operations that can |
| * be performed on that data. The operations can be any bit-wise combination of DND.MOVE, DND.COPY or |
| * DND.LINK. 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; |
| * |
| * 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> |
