Conversion between _tchar and Qstring in QT programming under Windows

Because in QT programming under Windows, if the use of Microsoft's API is involved, it is unavoidable to use _tchar these types, so on-line check, one of the foreigner's Forum someone gave this conversion, so take notes here:)
#ifdef UNICODE

#define QSTRINGTOTCHAR (x) (wchar_t*) X.utf16 ()

#define PQSTRINGTOTCHAR (x) (wchar_t*) X->utf16 ()

#define TCHARTOQSTRING (x) Qstring::fromutf16 ((x))

#define TCHARTOQSTRINGN (x, y) qstring::fromutf16 ((y))

#else

#define QSTRINGTOTCHAR (x) X.local8bit (). Constdata ()

#define PQSTRINGTOTCHAR (x) X->local8bit (). Constdata ()

#define TCHARTOQSTRING (x) Qstring::fromlocal8bit ((x))

#define TCHARTOQSTRINGN (x, y) qstring::fromlocal8bit ((y))

#endif
