示例 3：使用注册表连接远程节点

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

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

    SimpleSwitch srcSwitch; // create SimpleSwitch

    // Create node that hosts registry:
    QRemoteObjectRegistryHost regNode(QUrl(QStringLiteral("local:registry")));

    // Create node that will host source and connect to registry:
    QRemoteObjectHost srcNode(QUrl(QStringLiteral("local:replica")),
                              QUrl(QStringLiteral("local: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();
}

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