error: C1083: Cannot open file include: 'QKeyEvent':

  • 772

I can't include this library to my application. Try to include it as follows:

#include <QEvent>
#include <QKeyEvent>

However it shows me the following error:

user\filtro\customeventfilter.cpp:4: error: C1083: Cannot open file include: 'QKeyEvent': No such file or directory

    QKeyEventit is in the GUIQt library. If you do not incorporate this library to the project you will not be able to use this class.

    To include the library, simply add the following to the project:

    QT += gui

    It can also happen that you have something like:

    QT -= gui

    With what in theory it would be enough to eliminate said line.

    All the best.
