* The DragSourceEvent contains the event information passed in the methods of the DragSourceListener.
*
* <p>dragStart : When a drag operation is about to being, the following fields apply:
* <ul>
* <li>widget - (in) the DragSource object that is initiating the drag
* <li>time - (in) the time the drag action occurred
* <li>doit - (out) the application can set this value to false to prevent the drag from starting. Set to true by default.
* </ul></p>
*
* <p>dragSetData : When requesting data from the DragSource, the following fields apply:
* <ul>
* <li>widget - (in) the DragSource object that initiated the drag
* <li>time - (in) the time the drop occurred
* <li>dataType - (in) the type of data requested. This is a TransferData object and can be used with the Transfer subclasses.
* <li>data - (out) the application inserts the actual data here (must match the dataType). This is a Java object and
* the type of Java object that the application should insert here depends on the data type.
* For example, a TextTransfer requires a Java String containing the text; a FileTransfer requires
* a Java array of String with each String in the array representing the full path of the file.
* To determine what type of object you need to place in this field, consult the description of
* the Transfer subclass
* </ul></p>
*
* <p>dragFinished : When a drag operation has been completed, the following fields apply:
* <ul>
* <li>widget - (in) the DragSource object that initiated the drag
* <li>time - (in) the time the drop occurred
* <li>doit - (in) true if the operation performed successfully
* <li>detail - (in) the operation that was performed (DND.DROP_MOVE, DND.DROP_COPY, DND.DROP_LINK, DND.DROP_NONE)
* </ul></p>
