ObjectBase () | |
This default constructor is called implicitly from the constructor of user-derived classes, even if, for instance, Gtk::Button calls a different ObjectBase constructor. | |
ObjectBase (const char* custom_type_name) | |
A derived constructor always overrides this choice. | |
ObjectBase (const std::type_info& custom_type_info) | |
This constructor is a special feature to allow creation of derived types on the fly, without having to use g_object_new() manually. | |
virtual | ~ObjectBase ()=0 |
void | initialize (GObject* castitem) |
An Object for handling remote calls.
Instances of the MethodInvocation class are used when handling D-Bus method calls. It provides a way to asynchronously return results and errors.
The normal way to obtain a MethodInvocation object is to receive it as an argument to the SlotMethodCall that was passed to Gio::DBus::Connection::register_object().
|
virtual |
Glib::RefPtr<Connection> Gio::DBus::MethodInvocation::get_connection | ( | ) |
Gets the DBusConnection the method was invoked on.
Glib::RefPtr<const Connection> Gio::DBus::MethodInvocation::get_connection | ( | ) | const |
Gets the DBusConnection the method was invoked on.
Glib::ustring Gio::DBus::MethodInvocation::get_interface_name | ( | ) | const |
Gets the name of the D-Bus interface the method was invoked on.
Glib::RefPtr<Message> Gio::DBus::MethodInvocation::get_message | ( | ) |
Gets the DBusMessage for the method invocation.
This is useful if you need to use low-level protocol features, such as UNIX file descriptor passing, that cannot be properly expressed in the Variant API.
See <xref linkend="gdbus-server"> and <xref linkend="gdbus-unix-fd-client"> for an example of how to use this low-level API to send and receive UNIX file descriptors.
Glib::RefPtr<const Message> Gio::DBus::MethodInvocation::get_message | ( | ) | const |
Gets the DBusMessage for the method invocation.
