    ╰── GDBusObject

Prerequisites

GDBusObject requires GObject.

Known Implementations

GDBusObject is implemented by GDBusObjectProxy and GDBusObjectSkeleton.

Includes

#include <gio/gio.h>

Description

The GDBusObject type is the base type for D-Bus objects on both the service side (see GDBusObjectSkeleton) and the client side (see GDBusObjectProxy). It is essentially just a container of interfaces.

Functions

g_dbus_object_get_object_path ()

const gchar *
g_dbus_object_get_object_path (GDBusObject *object);

Gets the object path for object .

Parameters

object

A GDBusObject.

 

Returns

A string owned by object . Do not free.

Since: 2.30


g_dbus_object_get_interfaces ()

GList *
g_dbus_object_get_interfaces (GDBusObject *object);

Gets the D-Bus interfaces associated with object .

Parameters

object

A GDBusObject.

 

Returns

A list of GDBusInterface instances. The returned list must be freed by g_list_free() after each element has been freed with g_object_unref().

Since: 2.30


g_dbus_object_get_interface ()

GDBusInterface *
g_dbus_object_get_interface (GDBusObject *object,
                             const gchar *interface_name);

Gets the D-Bus interface with name interface_name associated with object , if any.

Parameters

object

A GDBusObject.

 

interface_name

A D-Bus interface name.

 

Returns

NULL if not found, otherwise a GDBusInterface that must be freed with g_object_unref().

Types and Values

GDBusObject

typedef struct _GDBusObject GDBusObject;

GDBusObject is an opaque data structure and can only be accessed using the following functions.


struct GDBusObjectIface

struct GDBusObjectIface {
  GTypeInterface parent_iface;

  /* Virtual Functions */
  const gchar     *(*get_object_path) (GDBusObject  *object);
  GList           *(*get_interfaces)  (GDBusObject  *object);
  GDBusInterface  *(*get_interface)   (GDBusObject  *object,
                                       const gchar  *interface_name);

  /* Signals */
  void (*interface_added)   (GDBusObject     *object,
                             GDBusInterface  *interface_);
  void (*interface_removed) (GDBusObject     *object,
                             GDBusInterface  *interface_);
};

Base object type for D-Bus objects.

Members

GTypeInterface parent_iface;

The parent interface.

 

get_object_path ()

Returns the object path. See g_dbus_object_get_object_path().

 

get_interfaces ()

Returns all interfaces. See g_dbus_object_get_interfaces().

 

get_interface ()

Returns an interface by name. See g_dbus_object_get_interface().

 

interface_added ()

Signal handler for the “interface-added” signal.

 

interface_removed ()

Signal handler for the “interface-removed” signal.

 

Since: 2.30

Signal Details

The “interface-added” signal

void
user_function (GDBusObject    *object,
               GDBusInterface *interface,
               gpointer        user_data)

Emitted when interface is added to object .

Parameters

object

The GDBusObject emitting the signal.

 

interface

The GDBusInterface that was added.

 

user_data

user data set when the signal handler was connected.

 

Flags: Run Last

Since: 2.30


The “interface-removed” signal

void
user_function (GDBusObject    *object,
               GDBusInterface *interface,
               gpointer        user_data)

Emitted when interface is removed from object .

Parameters

object

The GDBusObject emitting the signal.

 

interface

The GDBusInterface that was removed.

 

user_data

user data set when the signal handler was connected.

 

Flags: Run Last
