Struct ScrollableState 

pub struct ScrollableState { /* private fields */ }

Scroll input for content that supplies its own placement, such as a wheel.

The handler receives logical pixel deltas, positive down or right, and returns the amount consumed. A partial consumption stops a fling at a boundary. Modifier::scrollable supplies drag, wheel and fling gestures without applying a linear layout translation.

Implementations

pub fn dispatch_raw_delta(&self, delta: f32) -> f32

Applies a scroll delta and returns the amount consumed by the content.

pub fn is_dragging(&self) -> bool

Whether a pointer is currently dragging this content.
