  31  * @title: GRemoteActionGroup
  32  * @short_description: a #GActionGroup that interacts with other processes
  33  *
  34  * The GRemoteActionGroup interface is implemented by #GActionGroup
  35  * instances that either transmit action invocations to other processes
  36  * or receive action invocations in the local process from other
  37  * processes.
  38  *
  39  * The interface has <literal>_full</literal> variants of the two
  40  * methods on #GActionGroup used to activate actions:
  41  * g_action_group_activate_action() and
  42  * g_action_group_change_action_state().  These variants allow a
  43  * "platform data" #GVariant to be specified: a dictionary providing
  44  * context for the action invocation (for example: timestamps, startup
  45  * notification IDs, etc).
  46  *
  47  * #GDBusActionGroup implements #GRemoteActionGroup.  This provides a
  48  * mechanism to send platform data for action invocations over D-Bus.
  49  *
  50  * Additionally, g_dbus_connection_export_action_group() will check if
  51  * the exported #GActionGroup implements #GRemoteActionGroup and use the
  52  * <literal>_full</literal> variants of the calls if available.  This
  53  * provides a mechanism by which to receive platform data for action
  54  * invocations that arrive by way of D-Bus.
  55  *
  56  * Since: 2.32
