QT : Templated Q_OBJECT class

It is not possible to mix template and Q_OBJECT but if you have a subset of types you can list the slots and signals like this:

    class SignalsSlots : public QObject
    {
        Q_OBJECT

    public:
        explicit SignalsSlots(QObject *parent = 0) :
            QObject(parent) {}

    public slots:
        virtual void writeAsync(int value) {}
        virtual void writeAsync(float value) {}
        virtual void writeAsync(double value) {}
        virtual void writeAsync(bool state) {}
        virtual void writeAsync(svga::SSlideSwitch::SwitchState state) {}   

    signals:
        void readAsynkPolledChanged(int value);
        void readAsynkPolledChanged(float value);
        void readAsynkPolledChanged(double value);
        void readAsynkPolledChanged(bool state);
        void readAsynkPolledChanged(svga::SSlideSwitch::SwitchState state);
    };
...
template <class T>
class Abstraction : public SignalsSlots
{...
