What are you actually trying to do?

Hi,

To add to @raven-worx, without a .pro file how are you managing your project ? CMake ? QBS ?

@user4592357
so you are trying just to use a portion of Qt code in an arbitrary C++ application? Did i get this right?
If so it would be way more easier to use the native code working for what you are trying to do, than fiddling around with the Qt integration into your application (if possible at all).

they use .make files but i didn't find any such include there

What version of Qt are you using?

In old versions it's #include <QApplication> and QApplication::clipboard()

qt 4.8, and thanks, i used it and it solved my problem.

but i'm still curious cause this might happen to me again and i wanna know how can i include <QGuiApplication> in such projects?

You can't In Qt5 the gui module was split in 2, gui and widgets. gui includes QGuiApplication and widgets uses QApplication. In Qt4 there is no such distinction, QApplication is the only option.
