How to select next row in QTableView programmatically

Question

I have QTableView subclass that I am marking and saving its state with this :

connect(this,
        SIGNAL(clicked(const QModelIndex &)),
           


        

Answer 1

/*
 * selectNextRow() requires a row based selection model.
 * selectionMode = SingleSelection
 * selectionBehavior = SelectRows
 */

void MainWindow::selectNextRow( QTableView *view )
{
    QItemSelectionModel *selectionModel = view->selectionModel();
    int row = -1;
    if ( selectionModel->hasSelection() )
        row = selectionModel->selection().first().indexes().first().row();
    int rowcount = view->model()->rowCount();
    row = (row + 1 ) % rowcount;
    QModelIndex newIndex = view->model()->index(row, 0);
    selectionModel->select( newIndex, QItemSelectionModel::ClearAndSelect );
}
