Struct NestedScrollConnection 

pub struct NestedScrollConnection { /* private fields */ }

Scroll and fling consumption coordinated with an ancestor connection.

Implementations

impl NestedScrollConnection

pub fn new() -> Self

Creates an empty connection or motion value.

pub fn with_coordinate_scale(self, scale: State<f32>) -> Self

Uses the observed local-to-window scale for coordinate conversion.

pub fn in_space(&self, transform: LocalToWindow) -> NestedScrollSpace<'_>

Views this connection in the supplied caller coordinate space.

pub fn with_parent(self, parent: Option<Self>) -> Self

Sets the ancestor that receives motion remaining after local consumption.

pub fn with_pre_scroll_handler( self, handler: CallbackWith<PreScrollInput, ScrollDelta>, ) -> Self

Sets the callback that consumes displacement before the child scrolls.

pub fn with_post_scroll_handler( self, handler: CallbackWith<PostScrollInput, ScrollDelta>, ) -> Self

Sets the callback that consumes remaining displacement after the child scrolls.

pub fn with_pre_fling_handler( self, handler: CallbackWith<PreFlingInput, ScrollVelocity>, ) -> Self

Sets the callback that consumes velocity before the child flings.

pub fn pre_scroll( &self, available: ScrollDelta, source: ScrollEventSource, ) -> ScrollDelta

Dispatches displacement before child consumption and returns the consumed amount.

pub fn with_post_fling_handler( self, handler: CallbackWith<ScrollVelocity, ScrollVelocity>, ) -> Self

Sets the callback that consumes velocity after the child flings.

pub fn post_fling(&self, available: ScrollVelocity) -> ScrollVelocity

Dispatches velocity after the child flings and returns the consumed amount.

pub fn post_scroll( &self, consumed_by_child: ScrollDelta, available: ScrollDelta, source: ScrollEventSource, ) -> ScrollDelta

Dispatches remaining displacement after child consumption and returns the consumed amount.

pub fn pre_fling(&self, available: ScrollVelocity) -> ScrollVelocity

Dispatches velocity before the child flings and returns the consumed amount.

impl NestedScrollConnection

pub fn nearest() -> Option<Self>

Returns the nearest connection attached above the current build node.
