Detailed Description

This is a helper for listening to and accepting D-Bus connections.

Since Server derives from Initiable, its constructors can throw an exception if construction fails.

This can be used to create a new D-Bus server, allowing two peers to use the D-Bus protocol for their own specialized communication. A server instance provided in this way will not perform message routing or implement the org.freedesktop.DBus interface.

To just export an object on a well-known name on a message bus, such as the session or system bus, you should instead use Gio::DBus::own_name().

Creates a new D-Bus server that listens on the first address in address that works.

Once constructed, you can use g_dbus_server_get_client_address() to get a D-Bus address string that clients can use to connect.

To have control over the available authentication mechanisms and the users that are authorized to connect, it is strongly recommended to provide a non-nullptr Gio::DBus::AuthObserver.

Connect to the Gio::DBus::Server::signal_new_connection() signal to handle incoming connections.

The returned Gio::DBus::Server isn't active - you have to start it with g_dbus_server_start().

Gio::DBus::Server is used in this [example][gdbus-peer-to-peer].

This is a synchronous failable constructor. There is currently no asynchronous version.

Since glibmm 2.26:
Parameters
addressA D-Bus address.
flagsFlags from the Gio::DBus::Server::Flags enumeration.
guidA D-Bus GUID.

Returns
A Gio::DBus::Server or nullptr if error is set. Free with Glib::object_unref().
Exceptions
Glib::Error.

Glib::SignalProxy<bool(const Glib::RefPtr<Connection>&)> Gio::DBus::Server::signal_new_connection ( )
Slot Prototype:
bool on_my_new_connection(const Glib::RefPtr<Connection>& connection)

Flags: Run Last

Emitted when a new authenticated connection has been made. Use g_dbus_connection_get_peer_credentials() to figure out what identity (if any), was authenticated.

If you want to accept the connection, take a reference to the connection object and return true. When you are done with the connection call g_dbus_connection_close() and give up your reference. Note that the other peer may disconnect at any time - a typical thing to do when accepting a connection is to listen to the Gio::DBus::Connection::signal_closed() signal.

If Gio::DBus::Server::property_flags() contains Gio::DBus::Server::Flags::RUN_IN_THREAD then the signal is emitted in a new thread dedicated to the connection. Otherwise the signal is emitted in the [thread-default main context][g-main-context-push-thread-default] of the thread that server was constructed in.

You are guaranteed that signal handlers for this signal runs before incoming messages on connection are processed. This means that it's suitable to call g_dbus_connection_register_object() or similar from the signal handler.

Since glibmm 2.26:
Parameters
connectionA Gio::DBus::Connection for the new connection.
Returns
true to claim connection, false to let other handlers run.
void Gio::DBus::Server::start ( )

Starts server.

Since glibmm 2.26:
void Gio::DBus::Server::stop ( )

Stops server.
