Problem with include <QNetworkAccessManager>

[Armin]

Hi
I want to add #include <QNetworkAccessManager>
But i get error:

C:\Users\armin\Documents\DownloadManager\mainwindow.h:5: error: QNetworkAccessManager: No such file or directory

Why ?

Hi,
maybe you forgot to add: QT += network to your .pro file.

Hi,
I am not sure what you want me to explain. I would load my .pro file in a text editor, add the line, save it , run qmake and compile again and hope for the best.

Hi
If you are using Creator, simply click the .PRO file and it opens as any source file will.
