Hello,
I am new user Qt and I have got problem. So, I don't know how to save QMap with structure to file. I will show code.

Qt Code: 
  1. void Test::saveMap() {
  2.     QString fileName = QFileDialog::getSaveFileName(this, trUtf8("Save map to file"), "", trUtf8("Map (*.ttx);;All files (*)"));
  3.     if (fileName.isEmpty())
  4.         return;
  5.     else {
  6.         QFile file(fileName);
  7.         if (!file.open(QIODevice::WriteOnly)) {
  8.             QMessageBox::information(this, trUtf8("Can't to open file."), file.errorString());
  9.             return;
  10.         }
  11.         QDataStream out(&file);
  12.         out.setVersion(QDataStream::Qt_4_6);
  13.         out << map;
  14.     }
  15. }
To copy to clipboard, switch view to plain text mode 

Qt Code: 
  1. struct DataMap {
  2.     QString name;
  3.     QString name1;
  4.     QString name2;
  5. };
  6.  
  7. ...
  8.  
  9. QMap<QString, DataMap> map;
To copy to clipboard, switch view to plain text mode 

QMap is declared as private - it is all ok. If I save QMap without structure (declaration: QMap<QString, QString> map) all is ok, but if I save QMap with structure DataMap, I have got a lot of errors. How does it fix? How to save QMap with structure to file?

Thanks.

Goodbye.
