RemoteObject stops working after wrapping the replicanode

[Redman]

Hello

I used the simple switch remote object example with a registry from the docs.

main.cpp replica

   QRemoteObjectNode repNode;
   repNode.setRegistryUrl(QUrl(QStringLiteral("local:registry")));

   QSharedPointer<SimpleSwitchReplica> ptr;
   ptr.reset(repNode.acquire<SimpleSwitchReplica>());  // acquire replica of
                                                       // source from host

   R_SimpleSwitch rSwitch(ptr);

works perfect.

After wrapping that node into my own ROReceiverclass like this:

#ifndef RORECEIVER_H
#define RORECEIVER_H

#include <QRemoteObjectNode>

#include "r_simpleswitch.h"

class ROReceiver {
 public:
   ROReceiver(QUrl registryUrl);
 private:
   QRemoteObjectNode m_repNode;
};

#endif  // RORECEIVER_H


ROReceiver::ROReceiver(QUrl registryUrl) {
   m_repNode.setRegistryUrl(registryUrl);

   QSharedPointer<SimpleSwitchReplica> ptr;
   ptr.reset(
       m_repNode.acquire<SimpleSwitchReplica>());  // acquire replica of
                                                   // source from host node

   R_SimpleSwitch rSwitch(ptr);
}

and adjusting the main.cpp replica like followed

ROReceiver r(QUrl(QStringLiteral("local:registry")));

The example does not work anymore.

In the ctor of ROReceiver the replica is successfully aquired and the R_SimpleSwitch is initialized. In spite of all that the SimpleSwitchReplica::currStateChanged event does not fire anymore, so the slot which output the replica state never executes.

To me the code looks identical, except my ROReceiver wrapping that functionality.

Any ideas?

@Redman said in RemoteObject stops working after wrapping the replicanode:

ROReceiver::ROReceiver(QUrl registryUrl) {
m_repNode.setRegistryUrl(registryUrl);

QSharedPointer<SimpleSwitchReplica> ptr;
ptr.reset(
m_repNode.acquire<SimpleSwitchReplica>()); // acquire replica of
// source from host node

R_SimpleSwitch rSwitch(ptr);
}

C++ basics - how long does R_SimpleSwitch rSwitch(ptr); live?
