dankeschön, genau das war die Anleitung!
Ich habe da mal was vorbereitet, hier ist der Beispielcode ohne libs, mit integrierter Klasse:

hier kommt jetzt das, was ich versucht habe als .h und .cpp file zu erstellen.
Ich bin mir absolut nicht sicher, ob das gar nicht korrekt ist und ggf nur zufällig mit Fehlern funktionieren könnte, daher erst mal die Bitte zur Durchsicht:
