Slot inheritance

[nish]

just copy pasted your example and it works for me.

tst.h

class abstract_therapy : public QObject
{
    Q_OBJECT
public:
    void testFunction();
public slots:
    void testSlot(){ qDebug() << "in slot"; }
private:
    QTimer* m1;
};
 
class B : public abstract_therapy
{
    Q_OBJECT
public:
   void abc(){}
};

class abstract_therapy : public QObject
{
    Q_OBJECT
public:
    void testFunction();
public slots:
    void testSlot(){ qDebug() << "in slot"; }
private:
    QTimer* m1;
};

class B : public abstract_therapy
{
    Q_OBJECT
public:
   void abc(){}
};

    abstract_therapy* _therapy;
    _therapy = new B;
 
    _therapy->testFunction();
 
    return a.exec();
}

}

int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);

    abstract_therapy* _therapy;
    _therapy = new B;

    _therapy->testFunction();

    return a.exec();
}
