Hi,

i got a file which holds some lines like this:

19,sunshine live,0x1234
19,radio bob, 0xabcd
19,sputnik,0x1a2b

and so on..

My program reads this file and my goal is to output only the station name (2 entry in each line) in a QListWidget. Anyway the other 2 entries in each line should be hold in a vector or array, to use them later.

So far I got this, but it doesn't work right:

Qt Code: 
  1. void MainWindow::on_pushButton_clicked()
  2. {
  3.     QFile file(pfad);
  4.     if(!file.open(QFile::ReadOnly | QFile::Text)){
  5.         QMessageBox::warning(this,"..","keine datei gefunden");
  6.         return;
  7.     }
  8.  
  9.     QTextStream in_file(&file);
  10.     QString text;
  11.  
  12.     QVector<QVector<QString> > vectorOfVectorsOfStrings;
  13.     QVector<QString> zeile;
  14.  
  15.     while (!in_file.atEnd()) {
  16.                text = in_file.readLine();
  17.                QStringList split_text = text.split(",");
  18.  
  19.                for (int i = 0; i < 3; i++){
  20.  
  21.                    zeile.push_back(split_text.at(i));
  22.                    vectorOfVectorsOfStrings.push_back(zeile);
  23.                }
  24.            }
  25.  
  26.     file.close();
  27.  
  28.     for(int i = 0; i < vectorOfVectorsOfStrings.size(); i++)
  29.     {
  30.         for(int j = 0; j < vectorOfVectorsOfStrings[i].size(); j++)
  31.         {
  32.             ui->listWidget->addItem(vectorOfVectorsOfStrings[i][1]);
  33.         }
  34.     }
  35. }

The program is crashing with message [i] out of range. So i tried to set a fixed value just to so the output, and then my ListWidget was showing several times sunshine live. I guess the error is somewhere in here:

Qt Code: 
  1. while (!in_file.atEnd()) {
  2.                text = in_file.readLine();
  3.                QStringList split_text = text.split(",");
  4.  
  5.                for (int i = 0; i < 3; i++){
  6.  
  7.                    zeile.push_back(split_text.at(i));
  8.                    vectorOfVectorsOfStrings.push_back(zeile);
  9.                }
  10.            }
