QTableView help

I am using a QTableView to display a QSqlTableModel.

Code:

---

ui->tableView->setModel(myTableModel);
ui->tableView->show();

---

But when the user changes rows I want to get some information from the db and display it in a side widget. But in QTableView there is no signal that the row has been changed. I cannot use a QTableWiget because it will not "bind" to a QSqlTableModel...it says setModel() is private.

So QTableWidget will give a signal when a row has changed positions but it will not bind to the QSqlTableModel.

What is the best way to do this?

The signal is in the model - QAbstractItemModel::dataChanged().

That does not work. The only time I could get that signal to "fire" was when the contents of a cell changed. I want to know when a new row is "selected".

QAbstractItemView::selectionModel() and QItemSelectionModel::currentRowChanged().

I am new to this and I just don't understand how to set that up.

Here is what I have now. But everytime I select a new row it crashes.

Code:

---

MainWindow::MainWindow(QWidget *parent)
    : QMainWindow(parent), ui(new Ui::MainWindow)
{
 
    ui->setupUi(this);
 
    wrkTable = dbgmgr.OpenDB("moz_downloads","","downloads.sqlite");
 
    if (wrkTable)
    {
       connect(wrkTable, SIGNAL(dataChanged(QModelIndex, QModelIndex)),
            this, SLOT(rowMoved(QModelIndex, QModelIndex)));
 
        ui->tableView->setModel(wrkTable);
        ui->tableView->show();
        QItemSelectionModel sm(wrkTable);
        ui->tableView->setSelectionModel(&sm);
 
        dbgmgr.DebugInfo(true);
    }
    else
        qDebug() << "Error: " << dbgmgr.error;
}
 
void MainWindow::rowMoved(QModelIndex tl,QModelIndex br)
{
    qDebug() << "Row Moved! ";
}

I got it!

Thanks
