How to use Qhttp for downloading?? with the following code..

[Gokulnathvc]

Simplest way to download from the HTTP is below::

connect(&http,SIGNAL(done(bool)),this,SLOT(httpdone()));  //added in the constructor..

connect(&http,SIGNAL(done(bool)),this,SLOT(httpdone()));  //added in the constructor..

In the header file......Make the following changes...

QHttp http;
    QFile file;
 
private slots:
    bool on_pushButton_clicked();
    void httpdone();
 
signals:
    void done();
 
in the Qthttp.cpp file...
 
bool QtHttp::on_pushButton_clicked()
{
 
    QString strUrl="http://www.blabla.com//file";
       QUrl url = QUrl::fromUserInput(strUrl);
 
        QFileInfo fileInfo(url.path());
        QString strhost=url.encodedHost();
        QString filename=fileInfo.fileName();
        file.setFileName("C:\\Qt\\QHttp\\"+filename);
       http.setHost(url.host(),url.port(80));
       http.get(url.path(),&file);
 
       if(!file.open(QIODevice::WriteOnly))
       {
           QMessageBox::warning(NULL,"warning","file is not opened",QMessageBox::Ok);
       }
       file.write(http.readAll());
       http.close();
       return true;
 
}
 
void QtHttp::httpdone()
{
 
    file.close();
    Q_EMIT done();
}

QHttp http;
    QFile file;

private slots:
    bool on_pushButton_clicked();
    void httpdone();

signals:
