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