Struct SortableList 

pub struct SortableList { /* private fields */ }

A list that reorders by dragging a row, with a line showing where it will land, or with Alt and the arrows, Home and End. The arrows alone move between rows, and each move is announced to screen readers. The order belongs to the app, which applies what on_reorder tells it.

use ravenrs_reactive::State;
use ravenrs_widgets::{SortableList, Text, Ui};

let items = State::new(vec!["Warm", "Cool", "Matte"]);
let shown = items.get();
let moved = items.clone();
let list = SortableList::new(shown.len(), move |i| Text::new(shown[i]))
    .on_reorder(move |from, to| moved.update(|v| {
        let item = v.remove(from);
        v.insert(to, item);
    }));
let mut ui = Ui::new(list, ravenrs_style::Theme::raven_dark());
ui.update();

Implementations

impl SortableList

pub fn new<V>(count: usize, item: impl Fn(usize) -> V + 'static) -> SortableList

where V: View + 'static,

A list of count rows, in the order the app keeps.

pub fn key(self, key: impl Fn(usize) -> u64 + 'static) -> SortableList

What identifies a row, which is its position by default. With it, what a row keeps of its own goes with it when it moves.

pub fn on_reorder( self, handler: impl Fn(usize, usize) + 'static, ) -> SortableList

Called with where a row was and where it should go.

pub fn row_name(self, name: impl Fn(usize) -> String + 'static) -> SortableList

What screen readers call each row, for rows whose content does not say it.

pub fn spacing(self, spacing: f32) -> SortableList

Gap between rows (2 by default).

pub fn label(self, label: impl Into<String>) -> SortableList

What screen readers call the list, instead of the name in Labels.

pub fn grip(self, grip: bool) -> SortableList

Whether a row shows the mark that says it can be dragged (on by default).
