Struct ImageLightbox 

pub struct ImageLightbox { /* private fields */ }

Pictures over the whole app, one at a time, with zoom by ZoomPanView, a caption and a counter. It shows while open holds the index of a picture, and Escape or its X set it to None.

The arrows go to the previous and the next, and pan instead once zoomed in, Home and End go to the ends, and the keys of ZoomPanView zoom. Each picture starts fitted.

use ravenrs_core::{Color, ImageData};
use ravenrs_reactive::State;
use ravenrs_widgets::{ImageLightbox, LightboxItem};

let open = State::new(None::<usize>);
let pictures: Vec<LightboxItem> = ImageData::from_fn(64, 48, |_, _| Color::rgb(0.3, 0.3, 0.3))
    .map(|image| LightboxItem::new(image).caption("IMG_0001.JPG"))
    .into_iter()
    .collect();
let lightbox = ImageLightbox::new(open.binding(), pictures);
