Check internet connection with QNetworkAccessManager question.

[Leon]

So i managed to check my internet connection with this way

.pro
@QT += network
@

.cpp

@#include <QNetworkAccessManager>

QNetworkAccessManager manager = new QNetworkAccessManager(this);
connect(manager, SIGNAL(finished(QNetworkReply)),
this, SLOT(replyFinished(QNetworkReply*)));
manager->get(QNetworkRequest(QUrl("http://google.com")));

void MainWindow::replyFinished(QNetworkReply* reply)

{

if (reply->error() == QNetworkReply::NoError)


    qDebug("connected");

else

    qDebug("error");

delete reply;

}@

but what if i dont want to call another void? i was thinking something like
@QNetworkAccessManager *manager = new QNetworkAccessManager(this);
manager->get(QNetworkRequest(QUrl("http://google.com")));
while(manager.isRunning()){}
//and here check the output of QNetworkReply...@

So the question is.. what should i put instead of while(manager.isRunning)
and what should i put instead of the comment above(//and here check the output of QNetworkReply)...

Here is what I did in QtWebService>
@
forever {
if (qsm.isReplyReady()) {
return qsm.replyRead();
} else {
qApp->processEvents(); // Ensures that application remains responive
// to events (prevents freezing).
}
@

You can see the whole code here: "link":https://gitorious.org/qwebservice/qwebservice/blobs/master/QWebService/sources/qwebmethod.cpp. Should be enough to check the body of ::isReplyReady().

Well i can see that you also connect the manager with voids...

and the code above has nothing to do with my networkreply..
what should i put instead of qsm?

I wrote that code quite a while ago ;) IIRC, the scheme was: create a replyFinished() slot like you do (+ store the reply, + set a notification bool), connect QNAM to it, then invoke the forever loop. This neatly changes an asynchronous API into a synchronous one (in QWS, I provide both for convenience).
