Struct SingleAxisScrollElementManager 

Source

Implementations§

Source§

impl SingleAxisScrollElementManager

Source

pub fn new( manager: SingleAxisScrollManager, id: ElementId, child_elements: Vec<ElementId>, button: Option<MouseButton>, ) -> Self

Creates a single-axis scroll manager for id.

Source

pub fn update(&mut self, provider: &dyn FullElementScrollState, dt: f32)

Advances scroll state for one frame.

No-op when layout bounds or internal size are unavailable for id.

Source

pub fn get_position(&self) -> Vector2

Returns the current clamped scroll offset.
