Methods to wait for the webpage to load finish?

[GCDX]

void MainWindow::on_pushButton_clicked()
{
    QString modules=stringpath;
    QUrl url2(modules);
    innerPage->setUrl(url2);//innerpage is a QWebview
    connect(innerPage, SIGNAL(loadFinished(bool)), SLOT(parse(bool)));
}

void MainWindow::parse(bool)
{
    QWebFrame *frameInner = innerPage->page()->mainFrame();
    QWebElement doc = frameInner->documentElement();
    QString json=doc.toPlainText();
//parsing code
print("parsing executed");
}

i realised i put on_pushButton_clicked in a loop as such:

int i=0;
While(i!=2){
i++;
print(i)
on_pushbutton_clicked();
}

outcome:
1
2
parsing executed.

i want parsing so be executed in every loop however i cant seem to be able to solve it?

I have been using this method to load webpages and parse information, however, it does not work in a loop, need solutions and explanations for this :(

Move the connect out of on_pushButton_clicked or you'll raise multiple slots. put it where you construct innerPage (you are also missing this as receiver in the connect)

change your loop to:

QEventLoop waitParse;
connect(innerPage, SIGNAL(loadFinished(bool)), &waitParse, SLOT(quit()));
for(int i=0;i<2;++i){
on_pushbutton_clicked();
waitParse.exec();
}

@GCDX Please do not post same question more than once.

@VRonin In my opinion it would be better to not to use QEventLoop. He can simply take next URL in void MainWindow::parse(bool) if there is any.
Actually @J-Hilk already suggested it in the other thread

1. Put all URLs in a container
2. Start with the first one
3. In MainWindow::parse(bool) take the next one from the container
