Qt Code: 
  1. void Victims::load()
  2. {
  3.     int grows = ui->tw->rowCount();
  4.     int gcols = ui->tw->columnCount();
  5.  
  6.     QSettings set("victims");
  7.     set.beginGroup("setting");
  8.  
  9.     for(int i = 0; i < grows ;i++)
  10.     {
  11.  
  12.         for(int j = 0; j < gcols ;j++)
  13.             {
  14.                 QTableWidgetItem* widgetItem = ui->tw->item(grows, gcols);
  15.                 QString ex = set.value("victims", str).toString();
  16.                 widgetItem->setText(ex);
  17.             }
  18.  
  19.     }
  20.  
  21.     set.endGroup();
  22. }
  23.  
  24.  
  25. void Victims::save()
