Example 3: Connections to Remote Nodes using a Registry

Set up the Source

The simpleswitch.h and simpleswitch.cpp sources from Example can be used without modification. The difference is in the way a host node is created and connected to the registry:

main.cpp

#include <QCoreApplication>
#include "simpleswitch.h"

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

    SimpleSwitch srcSwitch; // create SimpleSwitch

    QRemoteObjectRegistryHost regNode(QUrl(QStringLiteral("local:registry"))); // create node that hosts registry
    QRemoteObjectHost srcNode(QUrl(QStringLiteral("local:switch")), QUrl(QStringLiteral("local:registry"))); // create node that will host source and connect to registry
    //Note, you can add srcSwitch directly to regNode if desired.
    //We use two Nodes here, as the regNode could easily be in a third process.

    srcNode.enableRemoting(&srcSwitch); // enable remoting of source object

    return a.exec();
}

Set up the Replica

The requestor object used for this example is the dynamic replica client discussed in Example 2.

The only modification is in main.cpp: a Registry node is created to acquire a Replica:

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

When run together with the source-side example, the output is identical to Example 1.
