- * Detects a drag and drop gesture.  This method is used
- * to detect a drag gesture when called from within a mouse
- * down listener.
- * 
- * <p>By default, a drag is detected when the gesture
- * occurs anywhere within the client area of a control.
- * Some controls, such as tables and trees, override this
- * behavior.  In addition to the operating system specific
- * drag gesture, they require the mouse to be inside an
- * item.  Custom widget writers can use <code>setDragDetect</code>
- * to disable the default detection, listen for mouse down,
- * and then call <code>dragDetect()</code> from within the
- * listener to conditionally detect a drag.
- * </p>
- *
- * @param event the mouse down event
- * 
- * @return <code>true</code> if the gesture occurred, and <code>false</code> otherwise.
- *
- * @exception IllegalArgumentException <ul>
- *   <li>ERROR_NULL_ARGUMENT when the event is null</li>
