Extract data from QTableView

I have a QTableView instance limited to a single row selection. I don't want to care about what cell the user presses, but it should always extract the data in (selectedRow,0).

So far I am doing the following:

QModelIndexList indices = _ui->_tbl->selectionModel()->selection().indexes();
QModelIndex id = indices.at(0).sibling(indices.at(0).row(),0);

Is there a better way?

You can get the data of the first cell of the selected row, if you go through the model. 

QModelIndex id = _ui->_tbl->model()->index(_ui->_tbl->currentIndex().row(),0);

Unfortunately Qt does not support (and I can't figure out why) a QModelIndex constructor with row and column as arguments.

As stated in Qt doc concerning currentIndex :

Unless the current selection mode is NoSelection, the item is also be selected

So you can do it quicker :

QModelIndex index = _ui->_tbl->currentIndex() ;
QModelIndex id = index.sibling(index.row(),0) ;

Using QItemSelectionModel::selectedRows takes out one step. It gives you the index at a particular column (o by default). Thus:

QModelIndex index = _ui->_tbl->selectionModel()->selectedRows(0).at(0);
