Class
AdwSpringAnimation
Description [src]
final class Adw.SpringAnimation : Adw.Animation {
/* No available fields */
}A spring-based AdwAnimation.
AdwSpringAnimation implements an animation driven by a physical model of a
spring described by AdwSpringParams, with a resting position in
AdwSpringAnimation:value-to, stretched to
AdwSpringAnimation:value-from.
Since the animation is physically simulated, spring animations don’t have a
fixed duration. The animation will stop when the simulated spring comes to a
rest - when the amplitude of the oscillations becomes smaller than
AdwSpringAnimation:epsilon, or immediately when it reaches
AdwSpringAnimation:value-to if
AdwSpringAnimation:clamp is set to TRUE. The estimated duration can
be obtained with AdwSpringAnimation:estimated-duration.
Due to the nature of spring-driven motion the animation can overshoot
AdwSpringAnimation:value-to before coming to a rest. Whether the
animation will overshoot or not depends on the damping ratio of the spring.
See AdwSpringParams for more information about specific damping ratio values.
If AdwSpringAnimation:clamp is TRUE, the animation will abruptly
end as soon as it reaches the final value, preventing overshooting.
Animations can have an initial velocity value, set via
AdwSpringAnimation:initial-velocity, which adjusts the curve without
changing the duration. This makes spring animations useful for deceleration
at the end of gestures.
If the initial and final values are equal, and the initial velocity is not 0, the animation value will bounce and return to its resting position.
