Trait containing all BaseEffect methods.

§Implementors

BaseEffect, Effect

Provided Methods§

source

fn is_time_effect(&self) -> bool

Get whether the effect is considered a time effect or not. An effect with registered time properties or set translation functions is considered a time effect.

§Returns

true if self is considered a time effect.

source

fn register_time_property(&self, child_property_name: &str) -> bool

Register a child property of the effect as a property that, when set, can change the timing of its input data. The child property should be specified as in TimelineElementExt::lookup_child().

You should also set the corresponding time translation using ges_base_effect_set_time_translation_funcs().

Note that self must not be part of a clip, nor can it have has-internal-source set to true.

§child_property_name

The name of the child property to register as a time property

§Returns

true if the child property was found and newly registered.

Object Safety§

This trait is not object safe.
