Superclasses: :class:`~gi.repository.Gtk.Gesture`, :class:`~gi.repository.Gtk.EventController`, :class:`~gi.repository.GObject.Object`





``GtkGestureRotate`` is a ``GtkGesture`` for 2-finger rotations.

Whenever the angle between both handled sequences changes, the
:obj:`~gi.repository.Gtk.GestureRotate.signals.angle_changed` signal is emitted.



Constructors
------------

.. rst-class:: interim-class

.. class:: GestureRotate
   :no-index:


   .. classmethod:: new() -> ~gi.repository.Gtk.Gesture

      Returns a newly created ``GtkGesture`` that recognizes 2-touch
      rotation gestures.














Methods
-------

.. rst-class:: interim-class

.. class:: GestureRotate
   :no-index:


   .. method:: get_angle_delta() -> float

      Gets the angle delta in radians.

      If ``gesture`` is active, this function returns the angle difference
      in radians since the gesture was first recognized. If ``gesture`` is
      not active, 0 is returned.
















Signals
-------

.. rst-class:: interim-class

.. class:: GestureRotate.signals
   :no-index:
   

   .. method:: angle_changed(angle: float, angle_delta: float) -> None

      Emitted when the angle between both tracked points changes.







      :param angle: Current angle in radians


      :param angle_delta: Difference with the starting angle, in radians
