Connect to function

[Armin]

Hi
you see code:

In class MainWindow:

void replyFinished(QNetworkReply *reply);

In void MainWindow::on_pushButton_clicked() :

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

In .cpp file :

void MainWindow::replyFinished(QNetworkReply *reply)

and don't work and i get message in Application Output:
QObject::connect: No such slot MainWindow::replyFinished(QNetworkReply*) in ..\DownloadManager\mainwindow.cpp:21
QObject::connect: (receiver name: 'MainWindow')

Why ?
Thanks

make sure you define it as slot in your .h file.

protected slots:
       void replyFinished(QNetworkReply *reply);

Alternatively you can use the new Qt5 syntax using function pointers (then it's not necessary to declare it as slot):

connect(manager , &QNetworkAccessManager::finished, this, &MainWindow::replyFinished);
