QT编程中的char*，wchar_t*与QString之间的转换

1. //QString to wchar_t:
   
2. const wchar_t * encodedName = reinterpret_cast<const wchar_t *>(fileName.utf16());
   
3. 
   
4. //QString to char * (general case):
   
5. const char * tmp = str.toUtf8().constData();
   
6. 
   
7. //wchar_t* to QString
   
8. wchar_t szMsg[100] = {0};
   
9. _stprintf(szMsg,L"Connect [%s] failed!",ssid);
   
10. QString str1= QString::fromWCharArray(szMsg);
    
11. 
    
12. //char* to QString
    
13. QStirng str2(tr("Please try again later."));
