Struct ScrollController 

pub struct ScrollController<T: Clone + 'static> { /* private fields */ }

Explicit programmatic control for a scrollable view.

A controller owns a reactive target and a monotonically increasing request generation. The generation makes repeated requests to the same target observable after the user has scrolled elsewhere.

Implementations

impl<T: Clone + 'static> ScrollController<T>

pub fn new(initial_target: T) -> Self

Creates a controller whose first target is initial_target.

pub fn scroll_to(&self, target: T)

Requests an immediate jump to target.

Panics

Panics if the request generation exceeds i32::MAX.

pub fn target(&self) -> Computed<T>

Returns the current requested target as a read-only signal.

pub fn generation(&self) -> Computed<i32>

Returns the request generation as a read-only signal.
