I still don't get it :-D All I get is nullptrs ...

Maybe I'm missing the forest for the trees?!

I now attached a minimal example showing my dilemma. After having put
demoui.rc to ~/.local/share/kxmlgui5/demo/, the GUI is setup nicely and all,
but how do I get a pointer to the "subMenu" menu? To e. g. assign an icon to
it's action or to disable the whole menu?!
