Hi,

I have an application written in JavaScript. I am trying to port it on on Maemo Platform using Qt.

I am facing problems in implementing "Save feature" to it. Whatever data I write on my application is saved in a "string" in a dosave() function of my JavaScript file.

I am using this code to interact with JavaScript function:

Qt Code: 
  1. void Test::on_pushButton2_clicked()
  2. {
  3.  
  4.         QVariant name;
  5.  
  6.         QString fileName = QFileDialog::getSaveFileName(this,
  7.                  tr("Save file"), "",
  8.                  tr("Myapp (*.app);;All Files (*)"));
  9.  
  10.              if (fileName.isEmpty())
  11.                  return;
  12.              else {
  13.                  QFile file(fileName);
  14.                  if (!file.open(QIODevice::WriteOnly)) {
  15.                      QMessageBox::information(this, tr("Unable to open file"),
  16.                          file.errorString());
  17.                      return;
  18.                  }
  19.  
  20.  
  21.            name = webView->page()->mainFrame()->evaluateJavaScript("dosave()");
  22.     }
  23. }
To copy to clipboard, switch view to plain text mode 

I am able to save my file but when I open it , I get blank file again with no data in it.
I am not able retrieve data.

Kindly suggest some solution to my problem.
What are the ways I can save the data returned by the JavaScript function and can get back same thing on my file when I open it.
How can I implement data structures or Hash table in Qt programming, where I can save the strings returned and then use them in function created in Javascript used to open my saved files ?
Kindly suggest some solutions.
