knuminput.h not available in QT Creator

I am using QT Creator on Fedora 28.

My GUI contains "KIntNumInput" objects. The compiler throws an error in ui_mainwindow.h (an automatically generated file that is not part of my project and cannot be edited):

knuminput.h: No such file or directory.

What do I have to install to be able to use this class?

Are there any alternatives in case it's not possible?

Edit: The file /usr/include/KF5/KDELibs4Support/knuminput.h exists, the compiler just doesn't find it

Solution

  • Solution: Added the include path /usr/include/KF5/KDELibs4Support/ to my project's configuration (.pro) file 

    INCLUDEPATH += /usr/include/KF5/KDELibs4Support

    Turns out this class is deprecated anyways and the Qt-equivalent (QSpinBox) which I, thanks to its not obvious name didn't find, should be used instead.
