Expand description

Complete drawing information for a scrollbar with all visual components.

This contains the resolved geometry and colors for all scrollbar parts:

Track: The background area where the thumb slides
Thumb: The draggable indicator showing current scroll position
Buttons: Optional up/down or left/right arrow buttons
Corner: The area where horizontal and vertical scrollbars meet

§button_decrement_bounds: Option<LogicalRect>

Optional decrement button bounds (up/left arrow)

§button_increment_bounds: Option<LogicalRect>

Optional increment button bounds (down/right arrow)

§button_color: ColorU

Color for buttons

§opacity_key: Option<OpacityKey>

Optional opacity key for GPU-side fading animation.

§hit_id: Option<ScrollbarHitId>

Optional hit-test ID for WebRender hit-testing.

§clip_to_container_border: bool

Whether to clip scrollbar to container’s border-radius

§container_border_radius: BorderRadius
