Hi all.
I have writen code which downloads simple file. html file.
code is here:
Qt Code: 
  1. #include "mainwindow.h"
  2. #include "ui_mainwindow.h"
  3. #include <QFileInfo>
  4. #include <QMessageBox>
  5. MainWindow::MainWindow(QWidget *parent) :
  6.     QMainWindow(parent),
  7.     ui(new Ui::MainWindow)
  8. {
  9.     ui->setupUi(this);
  10.     url.setUrl("http://google.ge/");
  11.     ui->lineEdit->setText(url.toString());
  12.  
  13.     connect(ui->pushButton,SIGNAL(clicked()),this,SLOT(downloadButton()));
  14. }
  15.  
  16. MainWindow::~MainWindow()
  17. {
  18.     delete ui;
  19. }
  20. void MainWindow::downloadButton()
  21. {
  22.     url.setUrl(ui->lineEdit->text());
  23.     request.setUrl(url);
  24.     QFileInfo fileInfo = url.path();
  25.     QString fileName = fileInfo.fileName();
  26.     if(fileName.isEmpty())
  27.         fileName = "index.html";
  28.  
  29.     file = new QFile(fileName);
  30.     file->open(QIODevice::WriteOnly);
  31.  
  32.     startRequest();
  33. }
  34. void MainWindow::startRequest()
  35. {
  36.     reply = nmanager.get(request);
  37.     connect(reply,SIGNAL(finished()),this,SLOT(httpFinished()));
  38.     connect(reply,SIGNAL(readyRead()),this,SLOT(httpReady()));
  39.     //QMessageBox::information(this,"ads","asd");
  40. }
  41. void MainWindow::httpFinished()
  42. {
  43.     reply->deleteLater();
  44.     reply = 0;
  45.     file->close();
  46.     file = 0;
  47. }
  48. void MainWindow::httpReady()
  49. {
  50.     file->write(reply->readAll());
  51. }
To copy to clipboard, switch view to plain text mode 

I request page,that requires login autorization, username: and password:
I want my code to type automatically this fields(username and password) and then download page,which is after login autorization.

How can I do it?

p.s sorry fo my bad English.
