-Define slots in base class as pure virtual-Mark the virtual methods of base class as public slots-Don't connect those slots-emit signals from the subclass-the FIRST slot (defined as pure virtual) will keep getting called and any logic inside that slot will be executed. Workaround:-Define your slots in the subclass as public and not public slots Connecting C++ slots to QML signals - Qt 5 Blueprints Then, click on C++ Class in the pop-up window. The newly created class should at least inherit from QObject by choosing QObject as its base class. This is because a plain C++ class can't include Qt's slots or signals.
