  23. 			if ((currentGeneration != 0) && (evolutionInProgress)) {
  24. 				int answer = QMessageBox::question(this,
  25. tr("Save current population"), tr("Do you want to save the current population, in order to restore the simulation later?"),

  33. 				}
  34. 			}
  35.  
  36. 			// Quit the application
  37. 			::exit(0);
  38.  
  39. 		} else {

  45.
