Hi ,

In my example I use a model/view. My class is QSqlTableModel for the model and QTableView for the view.
I know save data to a file (.txt and even .csv if I wish).

Qt Code: 
  1. void Data_Example::txtExport()
  2. {
  3.  
  4.         QString fileName = QFileDialog::getSaveFileName(this,
  5.             tr("Save"), "",
  6.             tr("Save (*.txt);;All Files (*)"));
  7.  
  8.         if (fileName.isEmpty())
  9.             return;
  10.         else {
  11.             QFile file(fileName);
  12.             if (!file.open((QIODevice::WriteOnly) | QIODevice::Text))
  13.             {
  14.                 QMessageBox::information(this, tr("Unable to open file"),
  15.                     file.errorString());
  16.                 return;
  17.             }
  18.  
  19.             QString data;
  20.             data ="";
  21.  
  22.          for (int row = 0; row < model->rowCount(); ++row)
  23.          {
  24.            QSqlRecord record = model->record(row);
  25.                    for (int field = 0; field < record.count(); ++field)
  26.                    {
  27.                        if(field != 0 && field !=4 )
  28.                        {
  29.                            if (field > 1) data += "\n";
  30.  
  31.                data += record.field(field).value().toString();
  32.  
  33.                        }
  34.                    }
  35.          }
  36.  
  37.          QTextStream output(&file);
  38.          output.setCodec("UTF-8");
  39.          output << data;
  40.  
  41. }
To copy to clipboard, switch view to plain text mode 

And in my file (.txt) I have for instance:

Alicia
Tucker
21/09/1985

John
Smith
18/02/1964

Jessica
Houston
07/11/1993
Now, I search to load this file or an other file like this but I don't find solutions...
I start to write this:

void Data_Example::txtImport()
{

QString fileName = QFileDialog::getOpenFileName(this,
tr("Open My File"), "",
tr("My File (*.txt);;All Files (*)"));

if (fileName.isEmpty())
return;
else
{
QFile file(fileName);

if (!file.open(QIODevice::ReadOnly | QIODevice::Text))
{
QMessageBox::information(this, tr("Unable to open file"),
file.errorString());
return;
}

QTextStream input(&file);
QString line;
do
{
input >> data;
line = input.readLine();
} while(!line.isNull());
//file.close();


}
}
This part doesn't function because I don't have a loop which load data in my QslqTableModel.
If somebody know...

Thanks.
