242e33c0e383 Added dnd source, ByteArrayTransfer,Clipboard completed Frank Benoit <benoit@tionex.de> parents: diff changeset	56 * <p>A drag source is the object which originates a drag and drop operation. For the specified widget,
242e33c0e383 Added dnd source, ByteArrayTransfer,Clipboard completed Frank Benoit <benoit@tionex.de> parents: diff changeset	57 * it defines the type of data that is available for dragging and the set of operations that can
242e33c0e383 Added dnd source, ByteArrayTransfer,Clipboard completed Frank Benoit <benoit@tionex.de> parents: diff changeset	58 * be performed on that data. The operations can be any bit-wise combination of DND.MOVE, DND.COPY or
242e33c0e383 Added dnd source, ByteArrayTransfer,Clipboard completed Frank Benoit <benoit@tionex.de> parents: diff changeset	59 * DND.LINK. The type of data that can be transferred is specified by subclasses of Transfer such as
242e33c0e383 Added dnd source, ByteArrayTransfer,Clipboard completed Frank Benoit <benoit@tionex.de> parents: diff changeset	60 * TextTransfer or FileTransfer. The type of data transferred can be a predefined system type or it
242e33c0e383 Added dnd source, ByteArrayTransfer,Clipboard completed Frank Benoit <benoit@tionex.de> parents: diff changeset	61 * can be a type defined by the application. For instructions on how to define your own transfer type,
242e33c0e383 Added dnd source, ByteArrayTransfer,Clipboard completed Frank Benoit <benoit@tionex.de> parents: diff changeset	62 * refer to <code>ByteArrayTransfer</code>.</p>

242e33c0e383 Added dnd source, ByteArrayTransfer,Clipboard completed Frank Benoit <benoit@tionex.de> parents: diff changeset	64 * <p>You may have several DragSources in an application but you can only have one DragSource
242e33c0e383 Added dnd source, ByteArrayTransfer,Clipboard completed Frank Benoit <benoit@tionex.de> parents: diff changeset	65 * per Control. Data dragged from this DragSource can be dropped on a site within this application
242e33c0e383 Added dnd source, ByteArrayTransfer,Clipboard completed Frank Benoit <benoit@tionex.de> parents: diff changeset	66 * or it can be dropped on another application such as an external Text editor.</p>
242e33c0e383 Added dnd source, ByteArrayTransfer,Clipboard completed Frank Benoit <benoit@tionex.de> parents: diff changeset	67 *
242e33c0e383 Added dnd source, ByteArrayTransfer,Clipboard completed Frank Benoit <benoit@tionex.de> parents: diff changeset	68 * <p>The application supplies the content of the data being transferred by implementing the
242e33c0e383 Added dnd source, ByteArrayTransfer,Clipboard completed Frank Benoit <benoit@tionex.de> parents: diff changeset	69 * <code>DragSourceListener</code> and associating it with the DragSource via DragSource#addDragListener.</p>
242e33c0e383 Added dnd source, ByteArrayTransfer,Clipboard completed Frank Benoit <benoit@tionex.de> parents: diff changeset	70 *
242e33c0e383 Added dnd source, ByteArrayTransfer,Clipboard completed Frank Benoit <benoit@tionex.de> parents: diff changeset	71 * <p>When a successful move operation occurs, the application is required to take the appropriate
242e33c0e383 Added dnd source, ByteArrayTransfer,Clipboard completed Frank Benoit <benoit@tionex.de> parents: diff changeset	72 * action to remove the data from its display and remove any associated operating system resources or
242e33c0e383 Added dnd source, ByteArrayTransfer,Clipboard completed Frank Benoit <benoit@tionex.de> parents: diff changeset	73 * internal references. Typically in a move operation, the drop target makes a copy of the data
242e33c0e383 Added dnd source, ByteArrayTransfer,Clipboard completed Frank Benoit <benoit@tionex.de> parents: diff changeset	74 * and the drag source deletes the original. However, sometimes copying the data can take a long
242e33c0e383 Added dnd source, ByteArrayTransfer,Clipboard completed Frank Benoit <benoit@tionex.de> parents: diff changeset	75 * time (such as copying a large file). Therefore, on some platforms, the drop target may actually
242e33c0e383 Added dnd source, ByteArrayTransfer,Clipboard completed Frank Benoit <benoit@tionex.de> parents: diff changeset	76 * move the data in the operating system rather than make a copy. This is usually only done in
242e33c0e383 Added dnd source, ByteArrayTransfer,Clipboard completed Frank Benoit <benoit@tionex.de> parents: diff changeset	77 * file transfers. In this case, the drag source is informed in the DragEnd event that a
242e33c0e383 Added dnd source, ByteArrayTransfer,Clipboard completed Frank Benoit <benoit@tionex.de> parents: diff changeset	78 * DROP_TARGET_MOVE was performed. It is the responsibility of the drag source at this point to clean
242e33c0e383 Added dnd source, ByteArrayTransfer,Clipboard completed Frank Benoit <benoit@tionex.de> parents: diff changeset	79 * up its displayed information. No action needs to be taken on the operating system resources.</p>
