It’s compiling OK, just not working…

#include "mainwindow.h"
#include "ui_mainwindow.h"

MainWindow::MainWindow(QWidget *parent)
    : QMainWindow(parent)
    , ui(new Ui::MainWindow)
{
    ui->setupUi(this);

    CreateModel();
}

MainWindow::~MainWindow()
{
    delete ui;
}

void MainWindow::CreateModel(void)
{
    QSqlTableModel *model = new QSqlTableModel(this);
    model->setTable("Text");
    model->setEditStrategy(QSqlTableModel::OnManualSubmit);
    model->select();
    model->setHeaderData(0, Qt::Horizontal, tr("A"));
    model->setHeaderData(1, Qt::Horizontal, tr("B"));
    model->setHeaderData(2, Qt::Horizontal, tr("C"));
    model->setHeaderData(3, Qt::Horizontal, tr("D"));
    model->setHeaderData(4, Qt::Horizontal, tr("E"));
    model->insertRows(0,0);

    ui->tableView->setModel(model);
    ui->tableView->hideColumn(0); // don't show the ID
    ui->tableView->show();
};

I have all the correct includes in the .pro file etc. And I have followed the instructions carefully.

Could anyone please help me?
