QFileDialog::getSaveFileName doesn't show file name.

[cydside]

In the following way:

QString nomeFile;
   nomeFile = QString
      (
      QDir::currentPath() + "/Export_%1.txt"
      )
      .arg(QDate::currentDate().toString("yyyy-MM-dd"));

QString nomeFile;
   nomeFile = QString
      (
      QDir::currentPath() + "/Export_%1.txt"
      )
      .arg(QDate::currentDate().toString("yyyy-MM-dd"));

To copy to clipboard, switch view to plain text mode 

it works!!!

thanks!
