Hi. I have a qtabewidget which has 10 rows and 2000 columns. When I save it to CSV after saving some rows(around 1500) its saying segmentation fault...Whats wrong with the code...
Qt Code: 
  1. void Read_Table::on_to_CSV_clicked()
  2. {
  3.     QFile f( "save1.csv" );
  4.  
  5.     if (f.open(QFile::WriteOnly))
  6.     {
  7.         QTextStream data( &f );
  8.         QStringList strList;
  9.         strList.clear();
  10.  
  11.         for( int c = 0; c < ui->O_Table->columnCount(); ++c )
  12.         {
  13.            // strList << "\" "+ui->O_Table->item( r, c )->text()+"\" ";
  14.             strList <<
  15.                        "\" " +
  16.                        ui->O_Table->horizontalHeaderItem(c)->data(Qt::DisplayRole).toString() +
  17.                        "\" ";
  18.  
  19.  
  20.         }
  21. data << strList.join( ";" )+"\n";
  22.         for( int r = 0; r < ui->O_Table->rowCount(); ++r )
  23.         {
  24.             strList.clear();
  25.             for( int c = 0; c < ui->O_Table->columnCount(); ++c )
  26.             {
  27.             strList << "\" "+ui->O_Table->item( r, c )->text()+"\" ";
  28.  
  29.  
  30.             }
  31.             data << strList.join( ";" )+"\n";
  32.         }
  33.         f.close();
  34.     }
  35.  
  36. }
