When I am using below code on Linux SLES 11 machine the .ini file is recreating for some reason so that I am not able to restore my settings.
Same code working fine on Windows machine.

Prb: I want to have recently opened file list on start up window, so that user can select quickly.

Qt Code: 
  1. Window::Window()
  2. {
  3.      restoreRecentFileList();
  4. }
  5.  
  6. Window::~Window()
  7. {
  8.       saveRecentFileList();
  9. }
  10.  
  11. void Window::saveRecentFileList()
  12. {
  13.     QSettings settings(m_settingsPath, QSettings::NativeFormat);
  14.     settings.setValue("recentFiles/list", QVariant(m_recentFilesList));
  15. }
  16.  
  17. void Window::restoreRecentFileList()
  18. {
  19.     QSettings settings(m_settingsPath, QSettings::NativeFormat);
  20.     m_recentFilesList = settings.value("recentFiles/list").toStringList();
  21. }
  22.  
  23. void Window::openFile(QString l_file)
  24. {
  25.  
  26.     if(isValidFile(l_file))
  27.     {
  28.         m_recentFilesList << l_file;
  29.  
  30.         done(QDialog::Accepted);
  31.         qDebug() << "connected to : " << l_file;
  32.     }
  33.     else
  34.     {
  35.        QMessageBox::information(this, "Information", "Please choose valid file", QMessageBox::Ok);
  36.     }
  37. }

//when i print m_recentFilesList , i am able to see expected values
