QHttpMultiPart: No such file or directory

[developerNancy]

I am trying to upload a file to a server in Multi-part and Now I got this error: QHttpMultiPart: No such file or directory.
I think I have to add some dependencies.
Is there any class or any dependencies for Multi part and I have already added QT += widgets in .pro file still same error.

What I have to do to remove this error ?

Hi,

That a network class. You need to add QT += network to your .pro file.

When in doubt look at the top of the class documentation there you have the module in which you can find the class.
