classmethod new(alpha, opacity_start, opacity_end)

Parameters:

• alpha (Clutter.Alpha or None) – a Clutter.Alpha instance, or None

• opacity_start (int) – minimum level of opacity

• opacity_end (int) – maximum level of opacity

Returns:

the newly created Clutter.BehaviourOpacity

Return type:

Clutter.Behaviour

Creates a new Clutter.BehaviourOpacity object, driven by alpha which controls the opacity property of every actor, making it change in the interval between opacity_start and opacity_end.

If alpha is not None, the Clutter.Behaviour will take ownership of the Clutter.Alpha instance. In the case when alpha is None, it can be set later with Clutter.Behaviour.set_alpha().
