QWindow is a GUI feature.  You can probably still use -no-widgets, but not -no-gui.  In any case, that example does not link with widgets even if they have been built: you can verify with ldd that the only Qt libs that it links with are libQt5Gui.so.5 and libQt5Core.so.5.  Therefore running that example will not load the widgets lib into memory.
