Struct Scrollable

pub struct Scrollable<'a, Message, Theme = Theme, Renderer = Renderer<Renderer, Renderer>>
where Theme: Catalog, Renderer: Renderer,
{ /* private fields */ }
Expand description

A widget that can vertically display an infinite amount of content with a scrollbar.

§Example

use iced::widget::{column, scrollable, vertical_space};

enum Message {
    // ...
}

fn view(state: &State) -> Element<'_, Message> {
    scrollable(column![

        vertical_space().height(3000),
        "You did it!",
    ]).into()
