Struct EditorScrollbarContext 

pub struct EditorScrollbarContext { /* private fields */ }

Current-frame editor geometry and its retained scroll offset. The editor applies caret scrolling before invoking the presentation callback. Like other ScrollbarHandle implementations, the content size includes the viewport’s padding, so subtracting the track size gives the scroll range.

Implementations

impl EditorScrollbarContext

pub fn axis(&self) -> ScrollbarAxis

pub fn scroll_viewport_size(&self) -> Size<Pixels>

The editor’s viewport without padding, for consumers that need its text layout size. Scrollbars should use ScrollbarHandle::content_size and ScrollbarHandle::viewport_bounds to calculate the scroll range; both include the padding around this viewport.
