SignalFlags
===================================================================

.. currentmodule:: gi.repository.GObject





.. class:: SignalFlags
   :no-contents-entry:






The signal flags are used to specify a signal's behaviour.













Fields
------

.. rst-class:: interim-class

.. class:: SignalFlags
   :no-index:
   

   .. attribute:: ACCUMULATOR_FIRST_RUN

      Only used in :obj:`~gi.repository.GObject.SignalAccumulator` accumulator
      functions for the :obj:`~gi.repository.GObject.SignalInvocationHint`::run_type field to mark the first
      call to the accumulator function for a signal emission.  Since 2.68.







   .. attribute:: ACTION

      Action signals are signals that may freely be emitted on alive
      objects from user code via :func:`~gi.repository.GObject.signal_emit` and friends, without
      the need of being embedded into extra code that performs pre or
      post emission adjustments on the object. They can also be thought
      of as object methods which can be called generically by
      third-party code.







   .. attribute:: DEPRECATED

      The signal is deprecated and will be removed
      in a future version. A warning will be generated if it is connected while
      running with G_ENABLE_DIAGNOSTIC=1.  Since 2.32.







   .. attribute:: DETAILED

      This signal supports "::detail" appendices to the signal name
      upon handler connections and emissions.







   .. attribute:: MUST_COLLECT

      Varargs signal emission will always collect the
      arguments, even if there are no signal handlers connected.  Since 2.30.







   .. attribute:: NO_HOOKS

      No emissions hooks are supported for this signal.







   .. attribute:: NO_RECURSE

      Signals being emitted for an object while currently being in
      emission for this very object will not be emitted recursively,
      but instead cause the first emission to be restarted.







   .. attribute:: RUN_CLEANUP

      Invoke the object method handler in the last emission stage.







   .. attribute:: RUN_FIRST

      Invoke the object method handler in the first emission stage.







   .. attribute:: RUN_LAST

      Invoke the object method handler in the third emission stage.
