Struct AnimatedOpacityView 

pub struct AnimatedOpacityView<State: 'static> { /* private fields */ }

A declarative opacity wrapper. See the module docs.

Implementations

impl<State: 'static> AnimatedOpacityView<State>

pub fn timing(self, timing: Timing) -> Self

Override the default (theme-resolved) fade timing.

pub fn cached(self, cached: bool) -> Self

Paint the child through a retained-page boundary (repaint_boundary) and drive the fade through its composite alpha (default false): a running fade over an unchanged child composites the retained page instead of painting the child every frame. Worth it for an expensive child that stays still while it fades.

fn teardown(&self, element: &mut AnimatedOpacityWidget, ctx: &mut BuildCtx<'_>)

Tear down element when this view is being removed.

fn message(&self, _element: &mut Self::Element, _state: &mut State)
