heres the code

Qt Code: 
  1. void MainWindow::setupSummaryTable()
  2. {
  3.  
  4.   s_table = new QTableWidget(0,5);
  5.  
  6.        QStringList labels;
  7.      labels << tr("IP Addresses") << tr("Received") << tr("Sent")
  8.             << tr("Total") << tr("# Packets");
  9.  
  10.      s_table->setHorizontalHeaderLabels(labels);
  11.      s_table->horizontalHeader()->setResizeMode(0, QHeaderView::Stretch);
  12.      s_table->horizontalHeader()->setResizeMode(1, QHeaderView::Stretch);
  13.      s_table->verticalHeader()->hide();
  14.      s_table->setShowGrid(true);
  15.      s_table->setSelectionBehavior(QAbstractItemView::SelectRows);
  16.      s_table->setEditTriggers(QAbstractItemView::NoEditTriggers);
  17.      s_table->setSelectionMode(QAbstractItemView::SingleSelection);  
  18.  
  20.  
  21.      list << packetTable->getKeys();
  22.  
  23.  
  24.      for(int j=0;j<list.size();j++)
  25.      {
  26.        s_table->insertRow(j);
  27.  
  28.        item = new QTableWidgetItem(list.at(j));
  29.  
  30.        QTableWidgetItem *item1 = packetTable->getIncoming(list.at(j));
  31.  
  32.        QTableWidgetItem *item2 = packetTable->getPacketCount(list.at(j));
  33.  
  34.        QTableWidgetItem *item3 = packetTable->getOutgoing(list.at(j));
  35.  
  36.        QTableWidgetItem *item4 = packetTable->getTotalBytes(list.at(j));
  37.  
  38.        s_table->setItem(j,0,item);
  39.  
  40.        s_table->setItem(j,1,item1);
  41.  
  42.        s_table->setItem(j,2,item3);
  43.  
  44.        s_table->setItem(j,3,item4);
  45.  
  46.        s_table->setItem(j,4,item2);
  47.  
  48.      }
  49.  
  50.  
  51. }
