wand

Wand is targeted as UI framework for web canvas based web applications.

Get Started

examples shows a basic sample application made with wand.

use wand;
use wasm_bindgen::prelude::*;

#[wasm_bindgen]
pub struct Application {
    app: wand::core::Application,
}

#[wasm_bindgen]
impl Application {
    pub fn new() -> Self {
        let mut app = wand::Application::new_with_canvas_id("canvas");
        let state = app.get_state();

        let mut scene = wand::Scene::default(state.clone());
        let section1 = app.new_section("section1", 1., 0.8, 0.01);
        // let section2 = app.new_section("section2", 0.8, 0.5, 0.01);
        let section3 = app.new_section("section3", 0.8, 1., 0.2);
        let section4 = app.new_section("section4", 1., 1., 0.2);
        let cursor_span = wand::TextSpan::new(state.clone(), "cursor", "Cursor:(N/A)", 1., 1.);
        {
            let mut section4_mut = section4.borrow_mut();
            section4_mut.add_span(cursor_span);
        }

        let section5 = app.new_section("section5", 1.,1., 0.2);
        let span = wand::TextSpan::new(state.clone(), "sample_span", "TextSpan", 1., 1.);
        {
            let mut section5_mut = section5.borrow_mut();
            section5_mut.add_span(span);
        }
        {
            let mut sec = section1.borrow_mut();
            sec.add_section(&section3);
            sec.add_section(&section4);
        }

        scene.add_section(&section1);
        /*
        scene.add_section(&section2);
        */
        // scene.add_section(&section4);
        scene.add_section(&section5);
        app.register(scene);

        Self {
            app,
        }
    }

    pub fn draw(&self) {
        self.app.draw();
    }

    pub fn on_size_change(&mut self) {
        self.app.on_resize();
    }

    pub fn on_mouse_move(&mut self, x: f64, y: f64) {
        self.app.on_mouse_move(x, y);
        {
            let state = self.app.get_state();
            let state = state.borrow();
            let cursor = state.get_span("cursor").unwrap().upgrade().unwrap();
            let mut cursor = cursor.borrow_mut();
            cursor.as_mut().set_text(&format!("Cursor: x: {}, y: {}", x, y));
        }
        self.app.draw();
    }
}

The window will looks like:
