Member Function Documentation

◆ export_interface_skeleton()

void Gio::DBus::InterfaceSkeleton::export_interface_skeleton	(	const Glib::RefPtr< Connection >&	connection,
		const Glib::ustring&	object_path
	)

Exports interface at object_path on connection.

This can be called multiple times to export the same interface onto multiple connections however the object_path provided must be the same for all connections.

Use g_dbus_interface_skeleton_unexport() to unexport the object.

Since glibmm 2.30:

Parameters

connection	A Gio::DBus::Connection to export interface on.
object_path	The path to export the interface at.

Exceptions

Glib::Error

◆ flush()

void Gio::DBus::InterfaceSkeleton::flush ( )

If interface has outstanding changes, request for these changes to be emitted immediately.

For example, an exported D-Bus interface may queue up property changes and emit the org.freedesktop.DBus.Properties::PropertiesChanged signal later (e.g. in an idle handler). This technique is useful for collapsing multiple property changes into one.

Since glibmm 2.30:

◆ get_connection() [1/2]

◆ get_connection() [2/2]

Glib::RefPtr<const Connection> Gio::DBus::InterfaceSkeleton::get_connection ( ) const

Gets the first connection that interface is exported on, if any.

Since glibmm 2.30:

Returns: A Gio::DBus::Connection or nullptr if interface is not exported anywhere. Do not free, the object belongs to interface.

Flags from the Gio::DBus::InterfaceSkeleton::Flags enumeration.

Since glibmm 2.30:

Default value: Gio::DBus::InterfaceSkeleton::Flags::NONE

Returns: A PropertyProxy that allows you to get or set the value of the property, or receive notification when the value of the property changes.

◆ property_g_flags() [2/2]

Glib::PropertyProxy_ReadOnly< Flags > Gio::DBus::InterfaceSkeleton::property_g_flags ( ) const

Flags from the Gio::DBus::InterfaceSkeleton::Flags enumeration.

Default value: Gio::DBus::InterfaceSkeleton::Flags::NONE

◆ set_flags()

void Gio::DBus::InterfaceSkeleton::set_flags ( Flags flags )

Sets flags describing what the behavior of skeleton should be.

Since glibmm 2.30:

Parameters

flags Flags from the Gio::DBus::InterfaceSkeleton::Flags enumeration.

◆ signal_authorize_method()

Glib::SignalProxy<bool(const Glib::RefPtr<MethodInvocation>&)> Gio::DBus::InterfaceSkeleton::signal_authorize_method ( )

Slot Prototype:: bool on_my_authorize_method(const Glib::RefPtr<MethodInvocation>& invocation)

Flags: Run Last

Emitted when a method is invoked by a remote caller and used to determine if the method call is authorized.

Note that this signal is emitted in a thread dedicated to handling the method call so handlers are allowed to perform blocking IO. This means that it is appropriate to call e.g. polkit_authority_check_authorization_sync() with the POLKIT_CHECK_AUTHORIZATION_FLAGS_ALLOW_USER_INTERACTION flag set.

If false is returned then no further handlers are run and the signal handler must take a reference to invocation and finish handling the call (e.g. return an error via g_dbus_method_invocation_return_error()).

Otherwise, if true is returned, signal emission continues. If no handlers return false, then the method is dispatched. If interface has an enclosing DBusObjectSkeleton, then the DBusObjectSkeleton::signal_authorize_method() signal handlers run before the handlers for this signal.

The default class handler just returns true.

Please note that the common case is optimized: if no signals handlers are connected and the default class handler isn't overridden (for both interface and the enclosing DBusObjectSkeleton, if any) and DBusInterfaceSkeleton::property_g_flags() does not have the Gio::DBus::InterfaceSkeleton::Flags::HANDLE_METHOD_INVOCATIONS_IN_THREAD flags set, no dedicated thread is ever used and the call will be handled in the same thread as the object that interface belongs to was exported in.

Since glibmm 2.30:

Parameters

invocation A DBusMethodInvocation.

Returns: true if the call is authorized, false otherwise.

◆ unexport()

void Gio::DBus::InterfaceSkeleton::unexport ( )

Stops exporting interface on all connections it is exported on.

To unexport interface from only a single connection, use g_dbus_interface_skeleton_unexport_from_connection()

Since glibmm 2.30:

◆ unexport_from_connection()

void Gio::DBus::InterfaceSkeleton::unexport_from_connection ( const Glib::RefPtr< Connection >& connection )

Stops exporting interface on connection.

To stop exporting on all connections the interface is exported on, use g_dbus_interface_skeleton_unexport().

Since glibmm 2.32:

Parameters

connection A Gio::DBus::Connection.
