+ * This class makes it easy for applications to provide a drag object
+ * (for drag-n-drop or for clipboard) that has several representations
+ * of the same data, under different formats.
+ *
+ * Instead of creating a specific class for each case (as would otherwise
+ * be necessary), you can simply create independent drag objects (e.g.
+ * a TQImageDrag object and a KURLDrag object), and bundle them together
+ * using KMultipleDrag.
+ *
+ * Sample code for this:
+ *
+ * \code
+ * KMultipleDrag *drag = new KMultipleDrag( parentWidget );
+ * drag->addDragObject( new TQImageDrag( someQImage, 0 ) );
+ * drag->addDragObject( new KURLDrag( someKURL, 0 ) );
+ * drag->drag();
+ * \endcode
+ *
+ * Note that the drag objects added to the multiple drag become owned by it.
+ * For that reason their parent should be 0.
+ *
