Hello I am trying to load my .ini settings back into my UI.

I have the basic form down, from what I read in the QSettings doc and from what I could gather across the web, but I am still failing to understand how to load user saved text back into the UI.

Qt Code: 
  1. void DLP3Dprinter::saveprogram()
  2. {
  3.  
  4.     QSettings settings("Moose Soft", "Clipper");
  5.  
  6.         settings.beginGroup("MainWindow");
  7.         settings.setValue("size", size());
  8.         settings.setValue("pos", pos());
  9.         settings.setValue("Resolution",ui->StepResolutionText->toPlainText());
  10.         settings.endGroup();
  11.  
  12. }
  13. void DLP3Dprinter::readsettings()
  14. {
  15.     QSettings settings("Moose Soft", "Clipper");
  16.  
  17.      settings.beginGroup("MainWindow");
  18.      resize(settings.value("size", QSize(400, 400)).toSize());
  19.      move(settings.value("pos", QPoint(200, 200)).toPoint());
  20.      //settings.setUserData("Resolution",ui->StepResolutionText->toPlainText());
  21.      //ui->StepResolutionText->setPlainText(QApplication::translate("DLP3Dprinter"," ?????",0));
  22.  
  23.     // ui->StepResolutionText->setPlainText(settings.value("Resolution"));
  24.  
  25.      settings.endGroup();
To copy to clipboard, switch view to plain text mode 

I am trying various methods to attain my desired result, but my programming knowledge is limited. Any help would be appreciated. I am sure this is pretty simple, once understood.

Thanks!
