QT QUdpSocket：没有这样的文件或目录

Question

I am using QT Creator to build a program that receives UDP data packets.

I am trying to include QUdpSocket library, but it throws the following error (triplicated in the same line):

mainwindow.h:6: error: C1083: 'QUdpSocket': No such file or directory

I've included QT += network line to .pro file, but it keeps returning the error.

I've checked that I have QUdpSocket and qudpsocket.h files in "C:\\Qt\\5.5\\msvc2012\\include\\QtNetwork" directory.

Can anyone help me with this?

Thanks in advance.

Version: Qt Creator 3.4.1 based on Qt 5.4.2 (MSVC 2013, 32bit)

您需要在源代码文件中添加以下内容：

include <QtNetwork/QUdpSocket>
