    Hi,
    I have a QStandardItemModel displaying data in a TableView. Which is the best way to find the row and column of a cell the user clicked on?
    Thank you.

      Hi!
      U should use indexAt(QPoint), rowAt(int) and columnAt(int) inside overriden mousePressEvent or mouseReleaseEvent methodes. Cooridnates can be obtained from the Event class.

          the view emits a signal with what you want already, you just need to connect it:
          QAbstractItemView::clicked(const QModelIndex &index)

              You can ask the model

                I figured it out.

                
                void MainWindow::on_tableView_clicked(const QModelIndex &index)
                {
                	int row = index.row ();
                    int column = index.column ();
                    qDebug() << "Index: " << "(" << row <<"," << column << ")";
                }
