Struct PagedDocumentView 

pub struct PagedDocumentView { /* private fields */ }

A bar with the page, the total and the zoom, over a column of pages of which only those that show are built, so the pictures of the others need not exist. Pictures come from whoever uses it, page by page: until one is ready, the page shows a placeholder of the right size. The fit follows the width of the view. Page Up, Page Down, Home and End move between pages, and +, - and 0 zoom.

use ravenrs_core::Size;
use ravenrs_reactive::State;
use ravenrs_widgets::{PagedDocumentView, Ui};

let page = State::new(0_usize);
let document = PagedDocumentView::new(120, |_| Size::new(595.0, 842.0), |_| None).page(page.binding());
let mut ui = Ui::new(document, ravenrs_style::Theme::raven_dark());
ui.update();

Implementations

impl PagedDocumentView

pub fn new( count: usize, page_size: impl Fn(usize) -> Size + 'static, picture: impl Fn(usize) -> Option<ImageData> + 'static, ) -> PagedDocumentView

A document of count pages, each of the size given by page_size at 100%, with the picture given by picture when it shows. Asked only for what shows, on each build, so it should hand over what is ready and start on what is not.

pub fn page(self, page: Binding<usize>) -> PagedDocumentView

The page in view, from 0. It follows the scroll, and setting it goes there.

pub fn zoom(self, zoom: Binding<ZoomView>) -> PagedDocumentView

The zoom, to share with other controls. Its center and viewport are not used.

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

A fixed height. It takes the height its parent gives it by default.

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

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