 1 | # Stray
 2 | 
 3 | Stray is a [SystemNotifierWatcher](https://www.freedesktop.org/wiki/Specifications/StatusNotifierItem/StatusNotifierWatcher/)
 4 | implementation which goal is to provide a minimalistic API to access tray icons and menu.
 5 | 
 6 | ## Examples
 7 | 
 8 | ### Start the system tray and listen for changes
 9 | ```rust, ignore
10 | use stray::{SystemTray};
11 | use tokio_stream::StreamExt;
12 | use stray::message::NotifierItemMessage;
13 | use stray::message::NotifierItemCommand;
14 | 
15 | #[tokio::main]
16 | async fn main() {
17 | 
18 |     // A mpsc channel to send menu activation requests later
19 |     let (ui_tx, ui_rx) = tokio::sync::mpsc::channel(32);
20 |     let mut tray = SystemTray::new(ui_rx).await;
21 | 
22 |     while let Some(message) = tray.next().await {
23 |         match message {
24 |             NotifierItemMessage::Update { address: id, item, menu } => {
25 |                 println!("NotifierItem updated :
26 |                     id   = {id},
27 |                     item = {item:?},
28 |                     menu = {menu:?}"
29 |                 )
30 |             }
31 |             NotifierItemMessage::Remove { address: id } => {
32 |                 println!("NotifierItem removed : id = {id}");
33 |             }
34 |         }
35 |     }
36 | }
37 | ```
38 | 
39 | ### Send menu activation request to the system tray
40 | 
41 | ```rust,  ignore
42 |  // Assuming we stored our menu items in some UI state we can send menu item activation request:
43 |  use stray::message::NotifierItemCommand;
44 | 
45 |  ui_tx.clone().try_send(NotifierItemCommand::MenuItemClicked {
46 |     // The submenu to activate
47 |     submenu_id: 32,
48 |     // dbus menu path, available in the `StatusNotifierItem`
49 |     menu_path: "/org/ayatana/NotificationItem/Element1/Menu".to_string(),
50 |     // the notifier address we previously got from `NotifierItemMessage::Update`
51 |     notifier_address: ":1.2161".to_string(),
52 |  }).unwrap();
53 | ```
54 | 
55 | ### Gtk example
56 | 
57 | For a detailed, real life example, you can take a look at the [gtk-tray](https://github.com/oknozor/stray/tree/main/gtk-tray).
58 | 
59 | ```shell
60 | git clone git@github.com:oknozor/stray.git
61 | cd stray/gtk-tray
62 | cargo run
63 | ```
64 |

 1 | # Stray
 2 | 
 3 | Stray is a minimal [SystemNotifierWatcher](https://www.freedesktop.org/wiki/Specifications/StatusNotifierItem/StatusNotifierWatcher/)
 4 | implementation which goal is to provide a minimalistic API to access tray icons and menu.
 5 | 
 6 | ## Examples
 7 | 
 8 | ### Start the system tray and listen for changes
 9 | ```rust, ignore
10 | use stray::{SystemTray};
11 | use tokio_stream::StreamExt;
12 | use stray::message::NotifierItemMessage;
13 | use stray::message::NotifierItemCommand;
14 | 
15 | #[tokio::main]
16 | async fn main() {
17 | 
18 |     // A mpsc channel to send menu activation requests later
19 |     let (ui_tx, ui_rx) = tokio::sync::mpsc::channel(32);
20 |     let mut tray = SystemTray::new(ui_rx).await;
21 | 
22 |     while let Some(message) = tray.next().await {
23 |         match message {
24 |             NotifierItemMessage::Update { address: id, item, menu } => {
25 |                 println!("NotifierItem updated :
26 |                     id   = {id},
27 |                     item = {item:?},
28 |                     menu = {menu:?}"
29 |                 )
30 |             }
31 |             NotifierItemMessage::Remove { address: id } => {
32 |                 println!("NotifierItem removed : id = {id}");
33 |             }
34 |         }
35 |     }
36 | }
37 | ```
38 | 
39 | ### Send menu activation request to the system tray
40 | 
41 | ```rust,  ignore
42 |  // Assuming we stored our menu items in some UI state we can send menu item activation request:
43 |  use stray::message::NotifierItemCommand;
44 | 
45 |  ui_tx.clone().try_send(NotifierItemCommand::MenuItemClicked {
46 |     // The submenu to activate
47 |     submenu_id: 32,
48 |     // dbus menu path, available in the `StatusNotifierItem`
49 |     menu_path: "/org/ayatana/NotificationItem/Element1/Menu".to_string(),
50 |     // the notifier address we previously got from `NotifierItemMessage::Update`
51 |     notifier_address: ":1.2161".to_string(),
52 |  }).unwrap();
53 | ```
54 | 
55 | ### Gtk example
56 | 
57 | For a detailed, real life example, you can take a look at the [gtk-tray](https://github.com/oknozor/stray/tree/main/gtk-tray).
58 | 
59 | ```shell
60 | git clone git@github.com:oknozor/stray.git
61 | cd stray/gtk-tray
62 | cargo run
63 | ```
64 |

21 |         while let Ok(mesage) = host_two.recv().await {

23 |             if count > 5 {
