Gio.DBusConnection.export_action_group

### Method

# Gio DBusConnectionexport_action_group

since: 2.32

#### Declaration [src]

    guint
    g_dbus_connection_export_action_group (
      GDBusConnection* connection,
      const gchar* object_path,
      GActionGroup* action_group,
      GError** error
    )

#### Description [src]

Exports `action_group` on `connection` at `object_path`.

The implemented D-Bus API should be considered private. It is subject to change in the future.

A given object path can only have one action group exported on it. If this constraint is violated, the export will fail and 0 will be returned (with `error` set accordingly).

You can unexport the action group using `g_dbus_connection_unexport_action_group()` with the return value of this function.

The thread default main context is taken at the time of this call. All incoming action activations and state change requests are reported from this context. Any changes on the action group that cause it to emit signals must also come from this same context. Since incoming action activations and state change requests are rather likely to cause changes on the action group, this effectively limits a given action group to being exported from only one main context.

Available since: 2.32

#### Parameters

`object_path`

  Type: `const gchar*`

  A D-Bus object path.

  The data is owned by the caller of the method.
  The value is a NUL terminated UTF-8 string.

`action_group`

  Type: `GActionGroup`

  An action group.

  The data is owned by the caller of the method.

`error`

  Type: `GError **`

  The return location for a recoverable error.

  The argument can be `NULL`.
  If the return location is not `NULL`, then you must initialize it to a `NULL` `GError*`.
  The argument will be left initialized to `NULL` by the method if there are no errors.
  In case of error, the argument will be set to a newly allocated `GError`; the caller will take ownership of the data, and be responsible for freeing it.

#### Return value

Type: `guint`

The ID of the export (never zero), or 0 in case of failure.
