Solved SIGNAL argument

[ODБOï]

Hi,

I'm trying to create c++ method to refactor my OPC UA subscription creation code.

...
privete :
       QScopedPointer<QOpcUaNode> nIndexNode; // node on the server is  "ns=4;s=MAIN.nIndex"
signals: 
     nIndexChanged();
...
// i want to make  following code more generic because i have more than 50 subscriptions
...
       nIndexNode.reset(m_client->node("ns=4;s=MAIN.nIndex"));      
       QObject::connect(node.data(),&QOpcUaNode::attributeUpdated,this,&MachineBackend::nIndexUpdated);

i want to create a method that takes
-a referenceon the private node pointer ( nIndexNode)
-a QString that represents the node id on the server (ns=4;s=MAIN.nIndex)
-something that allows me to call/emit the suited SIGNAL, here is my problem

  void uaSub(QScopedPointer<QOpcUaNode> &node, QString nodeId, /* the signal to be called */){

        node.reset(m_client->node(nodeId)); 
              QObject::connect(nIndexNode.data(),&QOpcUaNode::attributeUpdated,this,&/*MachineBackend::nIndexUpdated*/); // how to get the Signal name  ? 
    }

then i could simply call it

uaSub(nIndexNode,"ns=4;s=MAIN.nIndex",&MachineBackend::nIndexChanged)
uaSub(temperNode,"ns=4;s=MAIN.temperValue",&MachineBackend::temperChanged)
...

thank you in advance

i managed to solve this by myself

// nIndex update handler
   static void nIndexUpdated(QOpcUa::NodeAttribute attr, const QVariant &value){
        qDebug()<< "new value is  " << value;
    }

    void uaSub(QScopedPointer<QOpcUaNode> &node, QString nodeId , void (*theUpdateHandler)(QOpcUa::NodeAttribute attr,const QVariant &value)){
        node.reset(m_client->node(nodeId));

        QObject::connect(node.data(),&QOpcUaNode::attributeUpdated,[=](QOpcUa::NodeAttribute attr,const QVariant &value){
            theUpdateHandler(attr,value);
        });
    }

use

  uaSub(nIndexNode,"ns=4;s=MAIN.nIndex",nIndexUpdated);
