[Android] QT - tableview how to get the contents of a cell ?

void gz :: on_pushButton_2_clicked ()
{
static QSqlQueryModel * model = new QSqlQueryModel (ui-> tableView);
model-> setQuery (QString ("select * from yggzinfo;"));
int column = model-> columnCount (); / / get the number of columns
int row = model-> rowCount (); / / get the number of rows
QModelIndex index = model-> index (column, row, QModelIndex ());
ui-> lineEdit-> setText (index);
}

------ Solution ------------------------------------ --------
your code less secure. I rewrote it:

void gz::on_pushButton_2_clicked()
  {
      static QSqlQueryModel model(NULL);
      model.setQuery(QString("select * from yggzinfo;"));
      ui->tableView->setModel(&model);
      int column = ui->tableView->currentIndex().column(); //获得当前选中的列数
      int row = ui->tableView->currentIndex().row();       // 获得当前选中的行数
      //具体到你使用的model,有两种方式获取你想要的数据。最简单是
      QVariant currentData = model.data(ui->tableView->currentIndex());
      //或者通过record获取。
      QSqlRecord currentRecord=model.record(row);
      currentData = currentRecord.value(column);
      ui->lineEdit->setText(index);
  }

int currentRow = ui-> tableView-> currentIndex () row ();.
