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.
