如何实现系统托盘?

[huacnlee]

还没做过，GPUI 和 GPUI Component 没有这样的功能。这个可以试试用一些 Native API 实现。

有人之前在GPUI提过PR,但GPUI暂时拒绝了,因为没有人提过这个需求.

但我现在很需要系统托盘的功能.

托盘库：trayicon
window系统启动时增加下列代码

 #[cfg(target_os = "windows")]
    std::thread::spawn(move || {
        use windows::Win32::UI::WindowsAndMessaging::*;
        let mut msg = MSG::default();
        loop {
            unsafe {
                GetMessageW(&mut msg, None, 0, 0).as_bool().then(|| {
                    let _ = TranslateMessage(&msg);
                    let _ = DispatchMessageA(&msg);
                });
            }
        }
    });

run方法里增加订阅trayicon发出的事件

app.run(move |cx| {
        #[cfg(target_os = "windows")]
        {
            let (tx, mut rx) = tokio::sync::mpsc::channel::<TrayEvent>(10);
            let mut tray = tray::start_tray().unwrap();
            let _sub = CrossRuntimeBridge::global().subscribe(move |event: &TrayEvent| {
                tx.try_send(event.clone()).ok();
            });
            cx.spawn(async move |app| {
                let _subscription = _sub;
                while let Some(event) = rx.recv().await {
                    // println!("Tray event2: {:?}", event);
                    match event {
                        TrayEvent::DoubleClickTrayIcon => {
                            // println!("Double clicked");
                        }
                        TrayEvent::LeftClickTrayIcon => {
                            app.update(|app| {
                                //  println!("Left clicked");
                                app.windows().iter().for_each(|handle| {
                                    handle
                                        .update(app, |_, window, _| {
                                            #[cfg(target_os = "windows")]
                                            {

                                            window.activate_window();
                                        })
