Usage

use std::iter;
use tui_scrollview::{ScrollView, ScrollViewState};
use ratatui::{layout::Size, prelude::*, widgets::*};

struct MyScrollableWidget;

impl StatefulWidget for MyScrollableWidget {
    type State = ScrollViewState;

    fn render(self, area: Rect, buf: &mut Buffer, state: &mut Self::State) {
        // 100 lines of text
        let line_numbers = (1..=100).map(|i| format!("{:>3} ", i)).collect::<String>();
        let content =
            iter::repeat("Lorem ipsum dolor sit amet, consectetur adipiscing elit.\n")
                .take(100)
                .collect::<String>();

        let content_size = Size::new(100, 30);
        let mut scroll_view = ScrollView::new(content_size);

        // the layout doesn't have to be hardcoded like this, this is just an example
        scroll_view.render_widget(Paragraph::new(line_numbers), Rect::new(0, 0, 5, 100));
        scroll_view.render_widget(Paragraph::new(content), Rect::new(5, 0, 95, 100));

        scroll_view.render(buf.area, buf, state);
    }
}

Full Example

A full example can be found in the [examples] directory. scrollview.rs

This example shows a scrollable view with two paragraphs of text, one for the line numbers and one for the text. On top of this a Gauge widget is rendered to show that this can be used in combination with any other widget.
