Struct Filmstrip 

pub struct Filmstrip { /* private fields */ }

A horizontal strip of thumbnails that builds only what shows, so thousands cost the same as a few. Each cell comes from whoever uses it, with its own image, stars or badges; the strip draws the frame around it. A click selects alone, Ctrl or Cmd adds, and Shift takes a range; the arrows, Home and End move and keep the selected cell in view, Space adds, Enter activates. Arrows appear on the ends that have more to show.

use std::collections::BTreeSet;

use ravenrs_reactive::State;
use ravenrs_widgets::{Filmstrip, FilmstripCell, SelectionMode, Text, Ui};

let selected = State::new(BTreeSet::from([0_usize]));
let strip = Filmstrip::new(5_000, |cell: FilmstripCell| Text::new(format!("{}", cell.index + 1)))
    .selection(selected.binding())
    .mode(SelectionMode::Multiple);
let mut ui = Ui::new(strip, ravenrs_style::Theme::raven_dark());
ui.update();

Implementations

impl Filmstrip

pub fn new<V: View + 'static>( count: usize, cell: impl Fn(FilmstripCell) -> V + 'static, ) -> Self

A strip of count cells, with cell making the view of each one when it shows.

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

What identifies a cell, which is its position by default.

pub fn selection(self, selection: Binding<BTreeSet<usize>>) -> Self

The selected cells, to read and to change from outside. A single one that changes from outside is brought into view.

pub fn mode(self, mode: SelectionMode) -> Self

How cells can be selected (SelectionMode::Single by default).

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

Called with a cell on a double click or on Enter.

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

What screen readers call each cell.

pub fn cell_width(self, width: f32) -> Self

The width of each cell (96 by default).

pub fn height(self, height: f32) -> Self

The height of the strip (96 by default).

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

Gap between cells (6 by default).

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

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

pub fn fade(self, fade: Semantic) -> Self

The color the arrows fade from, which should be what is behind the strip.
