Mainwindow and Second window closes after saving QTableWidget contents in .csv file.

[Rututraj]

Hi all,
This is my first question here, hope to get get answer soon.
I have processed some data and displayed it on QTableWidget on second window.
I used Qtetxstream and QFile to save this data in .csv file using pushbutton.
But as soon as I click Pushbutton though the contents are saved, it closes both MainWindow and Second window and show message as The program has unexpectedly finished.

Code snippet:
void ErrorInfoTable::on_pushButton_Save_clicked()
{
QFile file(file path);

if(!file.open(QFile::WriteOnly | QFile::Truncate))
{
    QMessageBox::warning(this, "", "File not open");
}

for(int row = 0; row < NumberofErrors_ErrInfo; row++)
{
for(int col = 0; col < 6; col++)
{
QTextStream out(&file);
QString text = ui->tableWidget->item(row, col)->text();
out << text << ",";
file.flush();
if(col == 5)
{
out << "\n";
}
}

}

file.close();

}

Debug and try to find the line where exactly the crash happens

hi @Rututraj
said in Mainwindow and Second window closes after saving QTableWidget contents in .csv file.:

QString text = ui->tableWidget->item(row, col)->text();

best guess is, either row or col is to large, for the tableWidget index

@J-Hilk
Yes row index was getting out of range,
Thanks :)
