Tauri之单例+多窗口

Tauri 1.4 + React 18

单例可以通过tauri_plugin_single_instance实现，多窗口可以简单通过路由来实现

单例

    tauri::Builder::default().setup(|app| {let mut label = "home";let args: Vec<String> = std::env::args().collect();if args.len() > 1 {label = args.get(1).unwrap();}let mut runtime: tokio::runtime::Runtime = tokio::runtime::Runtime::new().expect("Unable to create a runtime");let s = runtime.block_on(create_window(label, &app.handle()));Ok(())}).plugin(tauri_plugin_single_instance::init(|app, argv, cwd| {let mut label = "home";if argv.len() > 1 {label = argv.get(1).unwrap();}let mut runtime = tokio::runtime::Runtime::new().expect("Unable to create a runtime");let s = runtime.block_on(create_window(label, app));}))

创建窗口的操作要异步，否则可能会卡死
setup时创建初始化窗口
tauri_plugin_single_instance处理重复打开操作

多窗口

async fn create_window(label: &str, app: &tauri::AppHandle) {let config = get_window_config(label);if let Some(window) = app.get_window(label) {let _ = window.show();let _ = window.set_focus();let _ = window.request_user_attention(Some(UserAttentionType::Informational));} else {let window = tauri::window::WindowBuilder::new(app,label,tauri::WindowUrl::App(label.parse().unwrap()),).center().title(config["title"].as_str().unwrap()).inner_size(config["width"].as_f64().unwrap(), config["height"].as_f64().unwrap()).build().unwrap();window.set_focus();}
}
