1. //QString to wchar_t:
2. const wchar_t * encodedName = reinterpret_cast<const wchar_t *>(fileName.utf16());
3. //QString to char * (general case):
4. const char * tmp = str.toUtf8().constData();
5. //wchar_t* to QString
6. wchar_t szMsg[100] = {0};
7. _stprintf(szMsg,L"Connect [%s] failed!",ssid);
8. QString str1= QString::fromWCharArray(szMsg);
9. //char* to QString
10. QStirng str2(tr("Please try again later."));
