Proper QUuid usage in Qt ? (7-Zip DLL usage problems (QLibrary, QUuid GUID conversion, interfaces))

Answer 1

You must use some conversion between the 2 types.

Looking at Qt documentation, I found that there is a GUID operator that transform a QUuid to a Windows GUID : http://doc.trolltech.com/4.6/quuid.html#operator-GUID

Of course, this is not cross-plateform.

Answer 2

You have to explicitly cast QUuid to GUID:

QUuid boo;
GUID uid = static_cast<GUID>(boo);
