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,可以在命令处理程序上或使用以下函数获取对象:Window
get_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");
}
