One question about store data in database

Armin

Hi
see this code :

void MainWindow::on_pushButton_2_clicked()
{
   QString name = ui->textEdit->toPlainText();
   QTableWidgetItem *itemobj = table->item(rowfirstlastname , 1);
   itemobj->setText(name);
   QString make = ui->comboBox->currentText();
   ui->label_7->setText(make);
}

If assume rowfirstlastname = 1 , name to be store in table database ? like ( row 1 and column 1 )

Hi,

Your question is not clear at all. Can you maybe rephrase it ?

Note that from your code, there's not database involved at all.

@SGaist Thanks
I need store data of QString name in table.
How can i do?

SGaist

What table would that be ?

Armin

@SGaist Thanks

Check this code :

class MainWindow;
}

class MainWindow : public QMainWindow
{
    Q_OBJECT

public:
    explicit MainWindow(QWidget *parent = 0);
    ~MainWindow();
    int row=1;
    int clm=7;
    int rowfirstlastname = 1;
   QTableWidget *table = new QTableWidget (row,clm);


private slots:
    void on_pushButton_2_clicked();


private:
    Ui::MainWindow *ui;
};

I changed my code :

 void MainWindow::on_pushButton_2_clicked()
{
     QString name = ui->textEdit->toPlainText();
     QTableWidgetItem *itemobj;
     itemobj->setText(name);
     table->setItem(rowfirstlastname , 1 , itemobj );
    QString make = ui->comboBox->currentText();
 }

and my program will crash ( has stopping work )

Hi
Your approach is ok but you forget to allocte the actual item.
QTableWidgetItem *itemobj; << just a pointer, it means can point to. Not IS an item.
must be
QTableWidgetItem *itemobj= new QTableWidgetItem;
