## Prerequisites

GDBusObjectManager requires GObject.

## Known Implementations

GDBusObjectManager is implemented by GDBusObjectManagerClient and GDBusObjectManagerServer.

## Includes

    #include <gio/gio.h>

## Description

The GDBusObjectManager type is the base type for service- and client-side implementations of the standardized org.freedesktop.DBus.ObjectManager interface.

See GDBusObjectManagerClient for the client-side implementation and GDBusObjectManagerServer for the service-side implementation.

## Functions

### g_dbus_object_manager_get_object_path ()

    const gchar *
    g_dbus_object_manager_get_object_path (GDBusObjectManager *manager);

Gets the object path that `manager` is for.

#### Parameters

manager | A GDBusObjectManager. |

#### Returns

A string owned by `manager` . Do not free.

Since 2.30

### g_dbus_object_manager_get_objects ()

    GList *

## Signal Details

### The `“interface-added”` signal

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

Emitted when `interface` is added to `object` .

This signal exists purely as a convenience to avoid having to connect signals to all objects managed by `manager` .

#### Parameters

manager | The GDBusObjectManager emitting the signal. |
object | The GDBusObject on which an interface was added. |
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 (GDBusObjectManager *manager,
                   GDBusObject        *object,
                   GDBusInterface     *interface,
                   gpointer            user_data)

Emitted when `interface` has been removed from `object` .

This signal exists purely as a convenience to avoid having to connect signals to all objects managed by `manager` .

#### Parameters

manager | The GDBusObjectManager emitting the signal. |
object | The GDBusObject on which an interface was removed. |
interface | The GDBusInterface that was removed. |
user_data | user data set when the signal handler was connected. |

Flags: Run Last

Since 2.30

### The `“object-added”` signal

    void
    user_function (GDBusObjectManager *manager,
                   GDBusObject        *object,
                   gpointer            user_data)

Emitted when `object` is added to `manager` .

#### Parameters

manager | The GDBusObjectManager emitting the signal. |
object | The GDBusObject that was added. |
user_data | user data set when the signal handler was connected. |

Flags: Run Last

Since 2.30

### The `“object-removed”` signal

    void
    user_function (GDBusObjectManager *manager,
                   GDBusObject        *object,
                   gpointer            user_data)

Emitted when `object` is removed from `manager` .

#### Parameters

manager | The GDBusObjectManager emitting the signal. |
object | The GDBusObject that was removed. |
user_data | user data set when the signal handler was connected. |

Flags: Run Last
