ScrollBar(s)

ScrollBar和ScrollBars这两个组件并不是单独去使用的，它们常使用在构建一个可以滚动的视图中充当属性

The ScrollBar and ScrollBars components are not used separately and are often used as properties in building a scrollable view

Example

#![allow(unused)]
fn main() {
ScrollXView = <ViewBase> {
    scroll_bars: <ScrollBars> {show_scroll_x: true, show_scroll_y: false}
}

// in widget define struct
#[derive(Live, LiveRegisterWidget, WidgetRef, WidgetSet)]
pub struct View {
    #[live]
    scroll_bars: Option<LivePtr>,
    #[rust]
    scroll_bars_obj: Option<Box<ScrollBars>>,
}
}

Default

#![allow(unused)]
fn main() {
ScrollBar = <ScrollBarBase> {
        bar_size: 10.0,
        bar_side_margin: 3.0
        min_handle_size: 30.0
        draw_bar: {
            //draw_depth: 5.0
            uniform border_radius: 1.5
            instance bar_width: 6.0
            instance pressed: 0.0
            instance hover: 0.0

            fn pixel(self) -> vec4 {
                let sdf = Sdf2d::viewport(self.pos * self.rect_size);
                if self.is_vertical > 0.5 {
                    sdf.box(
                        1.,
                        self.rect_size.y * self.norm_scroll,
                        self.bar_width,
                        self.rect_size.y * self.norm_handle,
                        self.border_radius
                    );
                }
