How to create a QDbus Object with multiple interfaces?

devel

There is a Telepathy API where a 'Client' must implement at least two dbus interfaces.

In the Empathy messenger has objects that look like this (if you inspect with D-feet):

/org/freedesktop/Telepathy/Client/Empathy/Auth
|-org.freedesktop.DBus.Introspectable
|-org.freedesktop.DBus.Properties
|-org.freedesktop.DBus.Properties
|-org.freedesktop.Telepathy.Client.Approuver
|-org.freedesktop.Telepathy.Client.Handler
|-org.freedesktop.Telepathy.Client.Interface.Requests
|-org.freedesktop.Telepathy.Client.Observer

But I'm managing to only create some separate objects:

/org/freedesktop/Telepathy/Client/MyClient/Handler
|-org.freedesktop.DBus.Introspectable
|-org.freedesktop.DBus.Peer
|-org.freedesktop.DBus.Properties
|-org.freedesktop.Telepathy.Client.Handler

/org/freedesktop/Telepathy/Client/MyClient/Observer
|-org.freedesktop.DBus.Introspectable
|-org.freedesktop.DBus.Peer
|-org.freedesktop.DBus.Properties
|-org.freedesktop.Telepathy.Client.Observer

I've done the generation from the Telepathy spec files:

qdbusxml2cpp -a Client Client.xml
qdbusxml2cpp -a ClientHandler Client_Handler.xml
qdbusxml2cpp -a ClientObserver Client_Observer.xml

And the code that's trying to instantiate it:

#include "Client.h"
#include "ClientHandler.h"
#include "ClientObserver.h"

#include <QCoreApplication>
#include <QDebug>

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

	QObject client;

	auto *telepathyClient = new ClientAdaptor(&client);

	auto *telepathyClienHandler = new HandlerAdaptor(&client);
	telepathyClienHandler->setObjectName("Handler");

	auto *telepathyClienObserver = new ObserverAdaptor(&client);
	telepathyClienObserver->setObjectName("Observer");

	auto dbusCnx = QDBusConnection::sessionBus();

	if (dbusCnx.registerObject("/org/freedesktop/Telepathy/Client/MyClient", &client, QDBusConnection::ExportAllContents | QDBusConnection::ExportChildObjects))
		qDebug("Client creation ok.");

	if (dbusCnx.registerService("org.freedesktop.Telepathy.Client.MyClient"))
		qDebug("Service creation ok.");

	return app.exec();
}

Does QDbus support creation of the objects with multiple interfaces?

Actually, TelepathyQt5 wrapper exists. It creates the interfaces correctly.

#include <TelepathyQt/AbstractClientHandler>

class MyHandler: public Tp::AbstractClientHandler
{
public:
	MyHandler(const Tp::ChannelClassSpecList& channelFilter);

	bool bypassApproval() const;

	void handleChannels(const Tp::MethodInvocationContextPtr<> &context, const Tp::AccountPtr &account, const Tp::ConnectionPtr &connection,
			const QList<Tp::ChannelPtr> &channels, const QList<Tp::ChannelRequestPtr> &requestsSatisfied, const QDateTime &userActionTime,
			const Tp::AbstractClientHandler::HandlerInfo &handlerInfo);
};

MyHandler::MyHandler(const Tp::ChannelClassSpecList &channelFilter) :
		Tp::AbstractClientHandler(channelFilter)
{
}

bool MyHandler::bypassApproval() const
{
	return false;
}

void MyHandler::handleChannels(const Tp::MethodInvocationContextPtr<> &context, const Tp::AccountPtr &account, const Tp::ConnectionPtr &connection,
		const QList<Tp::ChannelPtr> &channels, const QList<Tp::ChannelRequestPtr> &requestsSatisfied, const QDateTime &userActionTime,
		const Tp::AbstractClientHandler::HandlerInfo &handlerInfo)
{
	// do something
	context->setFinished();
}

#include <QCoreApplication>
#include <QDebug>

#include <TelepathyQt/ClientRegistrar>
#include <TelepathyQt/ChannelClassSpec>

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

	Tp::ClientRegistrarPtr registrar = Tp::ClientRegistrar::create();
	Tp::AbstractClientPtr handler = Tp::AbstractClientPtr::dynamicCast(Tp::SharedPtr<MyHandler>(new MyHandler(Tp::ChannelClassSpecList() << Tp::ChannelClassSpec::textChat())));
	registrar->registerClient(handler, "MyClient");

	return app.exec();
}
