> @broulik I do not understand. `KDEDModule` (which is a parent of `GtkConfig`) is `QObject`, not a `QGuiApplication`. Maybe I am missing something? You want me to create a connection with that signal within a module, so I don't have to ask from KCM to change a font via DBus?

kded (the application you're running in) is a `QApplication`, so from the constructor of your kdedmodule you could do

  #include <QApplication>
  connect(qApp, &QGuiApplication::fontChanged, this, [this](this QFont &font) {
      // now check if you have the new fonts
  });

I can't guarantee this will work (accessing `font` from there will actually deadlock :D but I am curious whether that signal is emitted properly, so you dont have to listen to or ask the font kcm to tell you.
