I can't include QKeyEvent library

[RIVOPICO]

Hi i can't include this library show me this message:
C1083: You can't open the file included : 'QKeyEvent': No such file or directory

I included this:
#include <QEvent>
#include <QKeyEvent>

@RIVOPICO
does #include <QtGui/QKeyEvent> work for you?
Did you compile Qt yourself?

You must include QT += gui to your .pro file.

[VRonin]

make sure you have QT += gui in your pro and rerun qmake

EDIT:
I was too slow
