QtRO exposing QList<CustomType> as a property.

batcher

Hello guys,

I am new to the QtRO Module, I created a simple host node which expose a QList of custom types (POD (QString name, QUrl endpoint)), in the client side I am getting a replica in the default state. the QList data are not transferred to the replica from the source.

ro.rep:

#include <QtCore>

POD Service(QString name, QUrl endpoint)

class Services
{
    PROP(QList<Service> services)
}

Server side:

#include <QObject>
#include "rep_ro_source.h"

class RemoteListServer: public ServicesSimpleSource
{
public:
    RemoteListServer(QObject* parent = nullptr): ServicesSimpleSource(parent) {
    Service* s1 = new Service("service 1", QUrl("local:s"));
    Service* s2 = new Service("service 2", QUrl("local:s"));
    QList<Service>* l = new QList<Service>();
    l->push_back(*s1);
    l->push_back(*s2);
    this->setServices(*l);
    }
};

Server main.cpp:

#include <QCoreApplication>
#include <QRemoteObjectHost>
#include "remotelistserver.h"

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

    RemoteListServer server;

    QRemoteObjectHost host(QUrl("local:s"));
    host.enableRemoting(&server);

    qDebug() << "Services exposed : " << server.services().count();

    return a.exec();
}

Client side main.cpp:

#include <QCoreApplication>
#include <QRemoteObjectNode>

#include "rep_ro_replica.h"

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

    QRemoteObjectNode node;
    if(node.connectToNode(QUrl("local:s"))) {
        qDebug() << "Connnected";
    } else {
        qDebug() << "Not connected : " << node.lastError();
    }

    QScopedPointer<ServicesReplica> ptr;
    ptr.reset(node.acquire<ServicesReplica>());

    if(ptr.data()->isReplicaValid()) {
        qDebug() << "Services found : " << ptr.data()->services().count();
    } else {
        qDebug() << "Replica is not valid : " << ptr.data()->state();
    }

    return a.exec();
}

I am new to this framework so maybe I am doing something stupid, Thank you for your valuable help.

OK, I finally figure it out, It was dumb, I had to wait till the replica get sync with the source, and this by handling the QRemoteObjectReplica stateChanged event. and it's all OK now.
