QtObject created and returned by singleton, how to attached slots ?

[SPlatten]

I have a singleton that manages object creation in C++ I return an instance of the created object to a QML property. C++:

    Q_INVOKABLE QObject* newInstance(const QString& crstrTag_) {
        return new staledata_t(crstrTag_);
    }

In the QML:

instance = DataMngr.newInstance(instanceID)

How can I assign QML slots to the singles that this instance C++ emits: C++ signals:

signals:
    void dataChanged(double dblData_);
    void interface(bool blnState_);
    void toolTip(QString strToolTip_);

Solved:

    Connections {
            target: instance
            function onDataChanged(dblData_) {
                rText.text = root.getValue(dblData_, true)
            }
    }
