pub struct ScrollTracker { /* private fields */ }Expand description
Tracks an element’s progress through another measured element, with configurable intersections, margins and optional spring smoothing. Retain anchors and this state; render their wrappers in the same window.
Implementations§
Source§impl ScrollTracker
impl ScrollTracker
Sourcepub fn new(
handle: ScrollHandle,
container: MotionAnchor,
target: MotionAnchor,
axis: Axis,
) -> Self
pub fn new( handle: ScrollHandle, container: MotionAnchor, target: MotionAnchor, axis: Axis, ) -> Self
Creates a target/viewport intersection tracker. Give the target anchor
scroll_source(handle.clone()) for current offsets before prepaint.
Sourcepub fn offsets(self, offsets: ScrollOffsets) -> Self
pub fn offsets(self, offsets: ScrollOffsets) -> Self
Sets start/end intersections.
Sourcepub fn margins(self, margins: [f64; 4]) -> Self
pub fn margins(self, margins: [f64; 4]) -> Self
Insets top/right/bottom/left viewport edges; negative margins expand them.
Sourcepub fn transition(self, transition: Transition) -> Self
pub fn transition(self, transition: Transition) -> Self
Uses the shared solver for optional smoothing.
Sourcepub fn frame(&mut self, window: &mut Window, cx: &App) -> ScrollFrame
pub fn frame(&mut self, window: &mut Window, cx: &App) -> ScrollFrame
Samples available measurements, tracks resize, and schedules only while
smoothing. A missing anchor holds the last value with ready=false.
