+ * by default.
+ * The other reasons for using this class are:
+ * @li it exports text/plain (for dropping/pasting into lineedits, mails etc.)
+ * @li it has support for metadata, shipped as part of the dragobject
+ * This is important, for instance to set a correct HTTP referrer (some websites
+ * require it for downloading e.g. an image).
+ *
+ * To create a drag object, use the KURLDrag constructor.
+ * To handle drops, use TQUriDrag::canDecode() and KURLDrag::decode()
