eframe 0.19.0

eframe - the [`egui`] framework crate If you are planning to write an app for web or native, and want to use [`egui`] for everything, then `eframe` is for you! To get started, see the [examples](https://github.com/emilk/egui/tree/master/examples). To learn how to set up `eframe` for web and native, go to and follow the instructions there! In short, you implement [`App`] (especially [`App::update`]) and then call [`crate::run_native`] from your `main.rs`, and/or call `eframe::start_web` from your `lib.rs`. ## Usage, native: ``` no_run use eframe::egui; fn main() { let native_options = eframe::NativeOptions::default(); eframe::run_native("My egui App", native_options, Box::new(|cc| Box::new(MyEguiApp::new(cc)))); } #[derive(Default)] struct MyEguiApp {} impl MyEguiApp { fn new(cc: &eframe::CreationContext<'_>) -> Self { // Customize egui here with cc.egui_ctx.set_fonts and cc.egui_ctx.set_visuals. // Restore app state using cc.storage (requires the "persistence" feature). // Use the cc.gl (a glow::Context) to create graphics shaders and buffers that you can use // for e.g. egui::PaintCallback. Self::default() } } impl eframe::App for MyEguiApp { fn update(&mut self, ctx: &egui::Context, frame: &mut eframe::Frame) { egui::CentralPanel::default().show(ctx, |ui| { ui.heading("Hello World!"); }); } } ``` ## Usage, web: ``` no_run #[cfg(target_arch = "wasm32")] use wasm_bindgen::prelude::*; /// Call this once from the HTML. #[cfg(target_arch = "wasm32")] #[wasm_bindgen] pub fn start(canvas_id: &str) -> Result { let web_options = eframe::WebOptions::default(); eframe::start_web(canvas_id, web_options, Box::new(|cc| Box::new(MyEguiApp::new(cc)))) } ``` ## Feature flags
