¶System tray

Feature-gated behind tray (tao dropped its built-in tray in 0.35, so this wraps the tray-icon crate).

elyra = { version = "0.1", features = ["tray"] }

¶Configuring the tray

use elyra::TrayConfig;

App::new()
    .tray(
        TrayConfig::new()
            .tooltip("My App")
            .title("My App")            // short text next to the icon (macOS/Linux)
            .item("open", "Open")       // custom item -> emits "open" on the "tray" channel
            .separator()
            .quit("Quit"),              // closes the app
    )
    .run();

Builder: new(), tooltip, title, item(id, label), separator(), quit(label). A simple solid-color icon is generated, so no image asset is required.

¶Handling clicks (frontend)

A custom item click emits its id on the "tray" event channel; a Quit item closes the app.

<script>
  import { channel } from "@elyra/runtime";
  const tray = channel("tray");   // e.g. "open"
  $effect(() => { if ($tray === "open") { /* focus / navigate */ } });
</script>

¶Notes

• The tray is created after the event loop initializes (required on macOS) and held for the program's lifetime.
• Menu clicks are routed through the event loop and re-emitted on the bus, so your frontend reacts the same way it does to any other event.
