+ * The DragSource class contains the data being dragged. The data can be in
+ * multiple formats, depending on the type of control that initiated the drag.
+ *
+ * <p>Each format of data is identified with a string. The
+ * <code>hasFormat()</code> method is used to determine if the object has
+ * data in that format. The <code>dataForFormat()</code> method is used
+ * to retrieve the data in the specified format.</p>
+ *
+ * <p>Data can be added directly using the <code>addData()</code> method,
+ * or indirectly using the <code>addHandler()</code> method. The
+ * <code>addHandler()</code> method registers a callback that will be called
+ * if the data is requested. This is useful for adding data in a non-native
+ * format that may require large computations or conversions. For example,
+ * if you have raw sound data you can add an MP3 format handler. The MP3
+ * conversion will only be done if the MP3 data is requested.</p>
