I spent whole day to find a Qt code to get a source code from some website(e.g. www.google.com), but everything I found, it didn't work. So, please can someone post the code how to get the source code from website? (I am using Qt creator and I don't know nothing about slot connecting, so please write the code without the slot connecting(or whatever is this) if it is even possible.
EDIT: Here is the code:

MainWindow::MainWindow(QWidget *parent) :

ui->buttonBack->setText(""); /*******************************/

}
MainWindow::~MainWindow()
{
delete ui;
}
void MainWindow::on_buttonBack_clicked()
{
ui->browser->back();
}
void MainWindow::on_buttonForward_clicked()
{
ui->browser->forward();
}
void MainWindow::on_buttonReload_clicked()
{
ui->browser->reload();
}
void MainWindow::on_buttonStop_clicked()
{
ui->browser->stop();
}
void MainWindow::on_browser_loadFinished(bool )
{
//QWebView webview;
//webview.setUrl (QUrl("http://www.google.com"));
//QString s = webview.page()->mainFrame()->toHtml();
//htmlOfPage = ui->browser.page()->mainFrame()->toHtml();
}
I have a file mainwindow.h and mainwindow.ui too, but I think that nobody needs those files, so I didn't post them.
#include <QApplication>
#include <QDebug>
#include <QtNetwork/QNetworkAccessManager>
#include <QtNetwork/QNetworkRequest>
#include <QtNetwork/QNetworkReply>
#include <QIODevice>
#include <QUrl>
class MyClass : public QObject{
Q_OBJECT
public slots:
void onFinished() {
QIODevice * content = static_cast<QIODevice*>(QObject::sender());
qDebug() << content->readAll();
content->deleteLater();
}
};
int main(int argc, char *argv[])
{
QApplication app(argc, argv);
QNetworkAccessManager nam;
MyClass obj;
QNetworkReply * reply = nam.get(QNetworkRequest(QUrl("http://google.com")));
QObject::connect(reply, SIGNAL(finished()), &obj, SLOT(onFinished()));
app.exec();
}
#include "main.moc"
加载中,请稍侯......
