 A Glib::wrap() method for this object.

Detailed Description

DBusProxy - Client-side proxies.

DBusProxy is a base class used for proxies to access a D-Bus interface on a remote object. A DBusProxy can be constructed for both well-known and unique names.

By default, DBusProxy will cache all properties (and listen to changes) of the remote object, and proxy all signals that gets emitted. This behaviour can be changed by passing suitable DBusProxyFlags when the proxy is created. If the proxy is for a well-known name, the property cache is flushed when the name owner vanishes and reloaded when a name owner appears.

If a DBusProxy is used for a well-known name, the owner of the name is tracked and can be read from property_g_name_owner(). Connect to the signal_notify() signal to get notified of changes. Additionally, only signals and property changes emitted from the current name owner are considered. This avoids a number of race conditions when the name is lost by one owner and claimed by another.

The generic signal_g_properties_changed() and signal_g_signal() signals are not very convenient to work with. Therefore, the recommended way of working with proxies is to subclass DBusProxy, and have more natural properties and signals in your derived class.

The C API docs has more information and an example.

Member Function Documentation

void Gio::DBusProxy::call ( const Glib::ustring method_name,
int  timeout_msec,
const SlotAsyncReady slot,
DBusCallFlags  flags = Gio::DBUS_CALL_FLAGS_NONE,
const Glib::VariantBase parameters = Glib::VariantBase(),
const Glib::RefPtr< Cancellable >&  cancellable = Glib::RefPtrCancellable >() 
)

Asynchronously invokes the method_name method on proxy.

If method_name contains any dots, then name is split into interface and method name parts. This allows using proxy for invoking methods on other interfaces.

If the DBusConnection associated with proxy is closed then the operation will fail with IO_ERROR_CLOSED. If cancellable is canceled, the operation will fail with IO_ERROR_CANCELLED. If contains a value not compatible with the D-Bus protocol, the operation fails with IO_ERROR_INVALID_ARGUMENT.

If the Variant is floating, it is consumed. This allows convenient 'inline' use of Glib::variant_new(), e.g.: |[ g_dbus_proxy_call (proxy, "TwoStrings", g_variant_new ("(ss)", "Thing One", "Thing Two"), G_DBUS_CALL_FLAGS_NONE, -1, 0, (GAsyncReadyCallback) two_strings_done, &data); ]|

This is an asynchronous method. When the operation is finished, callback will be invoked in the <link linkend="g-main-context-push-thread-default">thread-default main loop</link> of the thread you are calling this method from. You can then call g_dbus_proxy_call_finish() to get the result of the operation. See g_dbus_proxy_call_sync() for the synchronous version of this method.

Since glibmm 2.26:
Parameters:
method_name Name of method to invoke.
parameters A Variant tuple with parameters for the signal or 0 if not passing parameters.
flags Flags from the DBusCallFlags enumeration.
timeout_msec The timeout in milliseconds or -1 to use the proxy default timeout.
cancellable A Cancellable or 0.
callback A AsyncReadyCallback to call when the request is satisfied or 0 if you don't care about the result of the method invocation.
user_data The data to pass to callback.
void Gio::DBusProxy::call_finish ( Glib::VariantBase ret,
const Glib::RefPtr< AsyncResult >&  res 
)

Finishes an operation started with call().

Parameters:
ret An output variable in which to store the return.
res An AsyncResult obtained from the SlotAsyncReady passed to call().
Exceptions:
Glib::Error. 
void Gio::DBusProxy::call_sync ( Glib::VariantBase result,
const Glib::ustring method_name,
int  timeout_msec,
DBusCallFlags  flags = Gio::DBUS_CALL_FLAGS_NONE,
const Glib::VariantBase parameters = Glib::VariantBase(),
const Glib::RefPtr< Cancellable >&  cancellable = Glib::RefPtrCancellable >() 
)

Synchronously invokes the method_name method on proxy.

See call(), the asynchronous version of this method for more information.

Parameters:
result An output parameter in which to store the return.
method_name Name of method to invoke.
timeout_msec The timeout in milliseconds or -1 to use the proxy default timeout.
flags Flags from the DBusCallFlags enumeration.
parameters A Glib::VariantBase tuple with parameters for the signal.

const Glib::ustring name,
const Glib::ustring object_path,
const Glib::ustring interface_name,
const Glib::RefPtr< Cancellable >&  cancellable = Glib::RefPtrCancellable >() 
) [static]

Creates a proxy for accessing interface_name on the remote object at object_path owned by name at connection and synchronously loads D-Bus properties unless the DBUS_PROXY_FLAGS_DO_NOT_LOAD_PROPERTIES flag is used.

If the DBUS_PROXY_FLAGS_DO_NOT_CONNECT_SIGNALS flag is not set, also sets up match rules for signals. Connect to the DBusProxy::g-signal signal to handle signals from the remote object.

If name is a well-known name and the DBUS_PROXY_FLAGS_DO_NOT_AUTO_START flag isn't set and no name owner currently exists, the message bus will be requested to launch a name owner for the name.

This is a synchronous failable constructor. See g_dbus_proxy_new() and g_dbus_proxy_new_finish() for the asynchronous version.

See <xref linkend="gdbus-wellknown-proxy"> for an example of how DBusProxy can be used.

Since glibmm 2.26:
Parameters:
connection A DBusConnection.
flags Flags used when constructing the proxy.

const Glib::ustring object_path,
const Glib::ustring interface_name,
const SlotAsyncReady slot,
const Glib::RefPtr< Cancellable >&  cancellable = Glib::RefPtrCancellable >() 
) [static]

Creates a proxy for accessing interface_name on the remote object at object_path owned by name at connection and asynchronously loads D-Bus properties unless the DBUS_PROXY_FLAGS_DO_NOT_LOAD_PROPERTIES flag is used.

Connect to the DBusProxy::g-properties-changed signal to get notified about property changes.

If the DBUS_PROXY_FLAGS_DO_NOT_CONNECT_SIGNALS flag is not set, also sets up match rules for signals. Connect to the DBusProxy::g-signal signal to handle signals from the remote object.

If name is a well-known name and the DBUS_PROXY_FLAGS_DO_NOT_AUTO_START flag isn't set and no name owner currently exists, the message bus will be requested to launch a name owner for the name.

This is a failable asynchronous constructor - when the proxy is ready, callback will be invoked and you can use g_dbus_proxy_new_finish() to get the result.

void Gio::DBusProxy::set_cached_property ( const Glib::ustring property_name,
const Glib::VariantBase value 
)

If value is not 0, sets the cached value for the property with name property_name to the value in value.

If value is 0, then the cached value is removed from the property cache.

If proxy has an expected interface (see DBusProxy:g-interface-info), then property_name (for existence) and value (for the type) is checked against it.

If the value Variant is floating, it is consumed. This allows convenient 'inline' use of Glib::variant_new(), e.g. |[ g_dbus_proxy_set_cached_property (proxy, "SomeProperty", g_variant_new ("(si)", "A String", 42)); ]|

Normally you will not need to use this method since proxy is tracking changes using the <literal>org.freedesktop.DBus.Properties.PropertiesChanged</literal> D-Bus signal. However, for performance reasons an object may decide to not use this signal for some properties and instead use a proprietary out-of-band mechanism to transmit changes.

As a concrete example, consider an object with a property <literal>ChatroomParticipants</literal> which is an array of strings. Instead of transmitting the same (long) array every time the property changes, it is more efficient to only transmit the delta using e.g. signals <literal>ChatroomParticipantJoined(String name)</literal> and <literal>ChatroomParticipantParted(String name)</literal>.

Since glibmm 2.26:
Parameters:
property_name Property name.
value Value for the property or 0 to remove it from the cache.
void Gio::DBusProxy::set_default_timeout ( int  timeout_msec  ) 

Sets the timeout to use if -1 (specifying default timeout) is passed as timeout_msec in the g_dbus_proxy_call() and g_dbus_proxy_call_sync() functions.

See the DBusProxy:g-default-timeout property for more details.

Since glibmm 2.26:
Parameters:
timeout_msec Timeout in milliseconds.
void Gio::DBusProxy::set_interface_info ( const Glib::RefPtr< DBusInterfaceInfo >&  info  ) 

Ensure that interactions with proxy conform to the given interface.

For example, when completing a method call, if the type signature of the message isn't what's expected, the given Error is set. Signals that have a type signature mismatch are simply dropped.

See the DBusProxy:g-interface-info property for more details.

Since glibmm 2.26:
Parameters:
info Minimum interface this proxy conforms to or 0 to unset.
Glib::SignalProxy3< void,const Glib::ustring&,const Glib::ustring&,const Glib::VariantBase& > Gio::DBusProxy::signal_signal (  ) 
Prototype:
void on_my_signal(const Glib::ustring& sender_name, const Glib::ustring& signal_name, const Glib::VariantBase& parameters)
