Hi guys, im rather new to Qt and im following a book : Foudations of Qt Development. Im trying to use the QTableView to display data, but it doesnt seem to work, it only displays a empty viewer.

This is my constructor:
Qt Code: 
  1. MainDialog::MainDialog(QWidget *parent)
  2.     : QDialog(parent), ui(new Ui::MainDialog)
  3. {
  4.    // ui->setupUi(this);
  5.     QTableView *table = new QTableView;
  6.  
  7.     QStandardItemModel model(5, 2);
  8.     for (int row = 0; row < 5; ++row){
  9.         for (int col = 0; col < 2; ++col){
  10.             QStandardItem *item = new QStandardItem(QString("Row:%1, Column:%2").arg(row).arg(col));
  11.  
  12.             if (col == 0){
  13.                 for (int i = 0; i < 3; ++i){
  14.                     item->appendRow(new QStandardItem( QString("Item %1").arg(i)));
  15.                 }
  16.             }
  17.  
  18.             model.setItem(row, col, item);
  19.         }
  20.     }
  21.  
  22.     table->setModel(&model);
  23.     table->show();
  24.  
  25.     QHBoxLayout *layout = new QHBoxLayout;
  26.     layout->addWidget(table);
  27.     setLayout(layout);
  28. }
