Qt: c++: How to create a SIGNAL/SLOT when selecting a row in QTableView

Question

I have a QTableView which is working properly showing my model on the GUI. however, I would like to create a "SIGNAL/SLOT" that works when I select a row from the QTableView.

How can I do that?

Answer 1

You can do it in this way:

connect(ui->tableView->selectionModel(), SIGNAL(selectionChanged(const QItemSelection &, const QItemSelection &)),
             SLOT(slotSelectionChange(const QItemSelection &, const QItemSelection &))
            );

And the slot would be:

void MainWindow::slotSelectionChange(const QItemSelection &, const QItemSelection &)
{
            QModelIndexList selection = ui->tableView->selectionModel()->selectedRows();//Here you are getting the indexes of the selected rows

            //Now you can create your code using this information
}

I hope this can help you.

Use the currentRowChanged(const QModelIndex & current, const QModelIndex & previous) signal from the selection model (docs).
