Tauri 后端特定于窗口的事件

若要使用特定于窗口的事件通道，可以在命令處理程序上或使用以下函數(shù)獲取對象：Windowget_window

use tauri::{Manager, Window};

// the payload type must implement `Serialize` and `Clone`.
#[derive(Clone, serde::Serialize)]
struct Payload {
  message: String,
}

// init a background process on the command, and emit periodic events only to the window that used the command
#[tauri::command]
fn init_process(window: Window) {
  std::thread::spawn(move || {
    loop {
      window.emit("event-name", Payload { message: "Tauri is awesome!".into() }).unwrap();
    }
  });
}

fn main() {
  tauri::Builder::default()
    .setup(|app| {
      // `main` here is the window label; it is defined on the window creation or under `tauri.conf.json`
      // the default value is `main`. note that it must be unique
      let main_window = app.get_window("main").unwrap();

      // listen to the `event-name` (emitted on the `main` window)
      let id = main_window.listen("event-name", |event| {
        println!("got window event-name with payload {:?}", event.payload());
      });
      // unlisten to the event using the `id` returned on the `listen` function
      // an `once` API is also exposed on the `Window` struct
      main_window.unlisten(id);

      // emit the `event-name` event to the `main` window
      main_window.emit("event-name", Payload { message: "Tauri is awesome!".into() }).unwrap();
      Ok(())
    })
    .invoke_handler(tauri::generate_handler![init_process])
    .run(tauri::generate_context!())
    .expect("failed to run app");
}
