Function scrollbar_v 

pub fn scrollbar_v() -> ScrollbarVBuilder

scrollbar_v

Draw a vertical scrollbar for a scroll viewport.

Usage

Show and drag the vertical offset of overflowing content.

Parameters

• total — content extent in physical pixels; defaults to controller content.
• visible — viewport extent in physical pixels; defaults to controller viewport.
• offset — current scroll offset; defaults to the controller position.
• thickness — thickness of the scrollbar track.
• state — scroll controller the scrollbar reads and drives.
• scrollbar_behavior — visibility behavior (always, auto-hide, hidden).
• track_color, thumb_color, thumb_hover_color — themed colors.
• scrollbar_state — shared interaction state; created internally when absent.

Wheel input follows the attached viewport. A custom track without a viewport retains tap, drag and accessibility actions and leaves wheel input to ancestors.

Examples

use tessera_components::scrollable::{ScrollableController, scrollbar_v};
use tessera_components::theme::material_theme;
use tessera_ui::{Px, PxPosition, remember, tessera};
#[tessera]
fn tracked_content() {
    material_theme().child(|| {
        let controller = remember(ScrollableController::new);
        let offset = PxPosition::new(Px::ZERO, Px(-40));
        controller.with_mut(|controller| controller.set_scroll_position(offset));
        assert_eq!(
            controller.with(|controller| controller.child_position()),
            offset
        );
        scrollbar_v()
            .state(controller)
            .total(Px(600))
            .visible(Px(200));
    });
