+    This enum is used by toString(StringFormat) to control the formatting of the

+    \value WithBraces       The default, toString() will return five hex fields, separated by
+                            dashes and surrounded by braces. Example:
+                            {00000000-0000-0000-0000-000000000000}.
+    \value WithoutBraces    Only the five dash-separated fields, without the braces. Example:
+                            00000000-0000-0000-0000-000000000000.
+    \value Id128            Only the hex digits, without braces or dashes. Note that QUuid
+                            cannot parse this back again as input.
