iacoposk8

hello everyone ..
I would pick up the HTML code for a page remotely. this is my code and related errors.

[code]
#include "mainwindow.h"
#include "ui_mainwindow.h"
#include "QtNetwork/QtNetwork"

MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);

QNetworkAccessManager *manager = new QNetworkAccessManager(this);
     connect(manager, SIGNAL(finished(QNetworkReply*)),
             this, SLOT(replyFinished(QNetworkReply*)));

     manager->get(QNetworkRequest(QUrl("http://qtsoftware.com")));

}
[/code]

mainwindow.cpp:11: error: undefined reference to QNetworkAccessManager::QNetworkAccessManager(QObject*)' mainwindow.cpp:15: error: undefined reference to QNetworkRequest::QNetworkRequest(QUrl const&)'
mainwindow.cpp:15: error: undefined reference to QNetworkAccessManager::get(QNetworkRequest const&)' mainwindow.cpp:15: error: undefined reference to QNetworkRequest::~QNetworkRequest()'

Hi,

Did you added

@QT += network@

To your pro file ?

Though it should be in by default IIRC

no, I have not added. in which files should be placed? and in what position? thank you.

It needs to be added to your project file which is named after your project and has .pro as filename extension.

thanks a lot, now runs without errors.
in the bottom of the document I added this slot:
[code]
void MainWindow::replyFinished(QNetworkReply *pReply)
{
QByteArray data=pReply->readAll();
QString str(data);
qWarning() << str;
}
[/code]

but in the application otput not see anything, only ""
then enters into the slot but does not read anything.
