qt window下临时目录问题

   QDesktopServices::storageLocation(QDesktopServices::TempLocation);返回临时目录，有的机器可能返回到：C:\WINDOWS\TEMP,而不是用户临时目录下 Documents and Settings\[系统当前用户]\Local Settings\Temp\

 

下面函数纠正此问题，在win7,vista下未测试过

QString Form::getUserTempDir()
{
 QString tmpDir = QDesktopServices::storageLocation(QDesktopServices::TempLocation);
 QString userHome = QDesktopServices::storageLocation(QDesktopServices::HomeLocation);
 QString currentUser = userHome.mid(userHome.lastIndexOf("/") + 1);
 if (!tmpDir.isEmpty() && tmpDir.indexOf(currentUser)==-1)
 {
#ifdef Q_WS_WIN 
  int version = QSysInfo::windowsVersion();
  if (version == QSysInfo::WV_VISTA || version == QSysInfo::WV_WINDOWS7)
  {
   QString appData = QDesktopServices::storageLocation(QDesktopServices::ApplicationsLocation);
   tmpDir = QString("%1/Local/Temp").arg(userHome);
  }
  else
  {
   tmpDir = QString("%1/Local Settings/Temp").arg(userHome);
  }
           
  qDebug() << "Not right";
#endif
 }
 return tmpDir;
}
