Struct Autoscroll 

pub struct Autoscroll { /* private fields */ }

Middle-click autoscroll session anchored to a window position.

Speed scales linearly with pointer distance from the anchor up to full speed at AUTOSCROLL_FULL_SPEED_DISTANCE_PX, capped at MAX_AUTOSCROLL_SPEED_PX_PER_SEC, matching Windows conventions.

Implementations

impl Autoscroll

pub fn start(anchor: Point<Pixels>) -> Self

Begins a session anchored at anchor’s vertical position.

pub fn track(&mut self, pointer: Point<Pixels>)

Updates the tracked pointer position; call from hover/move handlers.

pub fn tick(&mut self, delta_seconds: f32) -> Pixels

Advances the session by delta_seconds using the latest tracked pointer and returns the distance to scroll this frame. Positive values scroll down; zero means the pointer sits within one pixel of the anchor.
