I want to make simple communication example on Qt Remote Objects. I want to make the communication peer-to-peer, therefore I'm trying to merge both Source and Replica of the same remote object functionality in one application (REPC_MERGED
tool used to generate Source and Replica base classes).
#include <QtCore/QCoreApplication>
#include "MyPeerHost.h"
#include "Client.h"
#include <QDebug>
static QString peer_node_name(int number)
{
QString ret = QString("peer_%1").arg(number);
return ret;
}
int main(int argc, char *argv[])
{
QCoreApplication a(argc, argv);
MyPeerHost peerHost; // just inherits auto-generated MyPeerSimpleSource
QUrl thisAddress = "local:" + peer_node_name(0);
QRemoteObjectHost sourceNode(thisAddress);
if(sourceNode.enableRemoting(&peerHost))
{
qInfo() << "Source remoting enabled successfully" << thisAddress;
QUrl remoteAddress = "local:" + peer_node_name(1);
QSharedPointer<MyPeerReplica> replica;
QRemoteObjectNode replicaNode;
if(replicaNode.connectToNode(remoteAddress))
{
qInfo() << "Replica connected to the address" << remoteAddress << "successfully";
replica.reset(replicaNode.acquire<MyPeerReplica>());
QString sourceClassName = peerHost.staticMetaObject.className();
qDebug() << "Replica wait for Source" << sourceClassName << "...";
if(replica->waitForSource(1000))
{
qInfo() << "Replica object completely initialized";
Client client;
client.setReplicaObject(replica);
client.sendMessage("AAA");
}
else
{
qCritical() << "Replica wait for Source" << sourceClassName << "FAILED" << replicaNode.lastError();
}
}
else
{
qCritical() << "Replica connect to the address" << remoteAddress << "FAILED" << replicaNode.lastError();
}
}
else
{
qCritical() << "Source remoting enable FAILED" << sourceNode.lastError();
}
return a.exec();
}
Application output:
Source remoting enabled successfully QUrl("local:peer_0") Replica connected to the address QUrl("local:peer_1") successfully Replica wait for Source "MyPeerHost" ... Replica wait for Source "MyPeerHost" FAILED QRemoteObjectNode::NoError
As you see, replicaNode
successfully connected to the non-existent node QUrl("local:peer_1")
.
What I am doing wrong?
