.. currentmodule:: gi.repository.Adw





.. class:: Easing
   :no-contents-entry:






Describes the available easing functions for use with
:obj:`~gi.repository.Adw.TimedAnimation`\.

New values may be added to this enumeration over time.




Methods
-------

.. rst-class:: interim-class

.. class:: Easing
   :no-index:


   .. method:: ease(value: float) -> float

      Computes easing with ``easing`` for ``value``\.

      ``value`` should generally be in the [0, 1] range.







      :param value: a value to ease














Fields
------

.. rst-class:: interim-class

.. class:: Easing
   :no-index:
   

   .. attribute:: EASE

      Cubic bezier tweening, with control points in (0.25, 0.1) and (0.25, 1.0).

      Increases in velocity towards the middle of the animation, slowing back down
      at the end.


      .. versionadded:: 1.7





   .. attribute:: EASE_IN

      Cubic bezier tweening, with control points in (0.42, 0.0) and (1.0, 1.0).

      Starts off slowly, with the speed of the animation increasing until complete.


      .. versionadded:: 1.7





   .. attribute:: EASE_IN_BACK

      Overshooting cubic tweening, with backtracking on start.






   .. attribute:: EASE_IN_BOUNCE

      Exponentially decaying parabolic (bounce) tweening,
      on start.






   .. attribute:: EASE_IN_CIRC

      Circular tweening.






   .. attribute:: EASE_IN_CUBIC

      Cubic tweening.






   .. attribute:: EASE_IN_ELASTIC

      Exponential tweening.






   .. attribute:: EASE_IN_OUT

      Cubic bezier tweening, with control points in (0.42, 0.0) and (0.58, 1.0).
